To Grandmother's House We Go: Peak Oil Is Here

Source: The Oil Drum

Posted by Prof. Goose on September 26, 2007 - 10:00am

I have intentionally paraphrased this wonderful Christmas song because it has much to say about the future after peak oil which I am now ready to say has already happened. As energy declines, we will indeed go to our grandmother's house--one without electricity and running water, sewer or septic and deep, mechanically pumped water wells. At least that was MY grandmother's house. She lived on the Kansas prairies of the 1890s. In the 1960s I asked my grandmother what the greatest invention of her life had been. She said electricity because before they had lights, everyone went to bed shortly after sun down because it was simply too dark to do to much. There was no air conditioning, so the summers were very hot. In the winter, trips to the outhouse were cold (and brutally awakening if during the middle of the night). While she had wood where she lived, about 100 miles west of her home, people had to burn dung as is done in Tibet today. See the picture below of the dung plastered against the house. When one wants to cook, one retrieves a patty.

Without cheap energy, we go back to my grandmother's house or one quite like it...

Yes, folks, peak oil is here, that thing that politicians don't speak of; that event which cornucopians (those who believe that we will not run out of energy) believe is a fraud or misunderstanding is here. The cornucopians believe we are wrong because many have predicted that we would run out of energy before and have been wrong. What they lacked was the 20-20 that hindsight gives one. Today, we can see the peak behind us.

First, how do we recognize when peak oil is about to happen or has happened? The first thing is that it always comes with a gradual decline in production. Steep changes in production curves are due to political or economic decisions. Let's look at Saudi production from 2001 to the present. (NB: Click all graphics throughout this post to expand them to full size.)

The first thing we notice is that it is declining from January 2001 to January 2002. That is the recession resulting from the collapse of the tech stock bubble, causing a worldwide reduction in oil demand. The world then began to recover. In January, 2003 political events in Venezuela shut in that country's oil. We find this

"January 12, 2003: OPEC held its 123rd meeting to review oil markets in Vienna, Austria. OPEC decided to raise its production quotas from 23 million barrels per day to 24.5 million barrels per day, effective February 1, 2003, in order to ensure adequate supplies of crude in response to the oil supply shortfall in Venezuela" http://www.eia.doe.gov/cabs/opec.html

This was a short-lived, very steep increase in production, followed a couple of months later by a nearly equivalent sharp drop in production. This is not a sign of peak oil; it is a sign of political manipulation of production. The next thing we notice is the sharp rise in production in April, 2004. This was due to the rise of price above $40/bbl, a level which OPEC had previously thought would cause a recession. They opened the taps to try to damp down the price. What they didn't count on was that China's and India's consumption had taken off like a rocket because of their economic growth. The price continued to rise, showing that scarcity of oil had come.

After a year and a half of all out production, we see the first signs of decline, normal natural decline in the Saudi production. The plateau of production is followed by a gradual decline in output. One might be tempted to say that the decline in production was due to declining prices, but this isn't true for the period from Oct. 2005 until July 2006. The price rose but the production declined. The gradualistic tail on Saudi production is what an oil field decline looks like.

Just as I was finishing writing this page, I saw this report.

Nicosia, Sept 8: Saudi Aramco in its Annual Review 2006 said that last year the company's crude oil production declined by 1.7 percent, while exports declined by 3.1 percent, compared with the previous year.

Crude oil production in 2006 averaged 8.9 million barrels of oil a day (b/d) and exports 6.9 million b/d. (http://www.dailyindia.com/show/172345.php/Saudi-Aramco-reports-oil-outpu... ) To me, the interesting thing about this is that with a 3.1 decrease in exports, this means that there is a reduction of 266,000 barrels per day available to the rest of the world. Production doesn't really matter to the rest of the world. Only exports matter. If the Saudi's used all of their oil, there would be nothing left for us to use. This data confirms that their exports are decreasing faster than their production is decreasing.

Let's take another example, the United Kingdom.

From 1995 until 1999, the UK production was a plateau. But in mid-1999, the monthly production began to gradually decline. I moved to the UK in August 2001, looked at the curves and told a colleague and fine geologist, Steve Daines, that the UK had peaked production. He disagreed. We made a bet for a lunch that at the end of 2000, the UK would produce no more than 130,000 tonnes of oil. I took below that figure, he took above. Instead of a lunch, he and his wife had me and my wife over for a wonderful Malaysian dinner cooked by his beautiful Malay wife. We ate that meal with gusto along with a Turkish couple, that they knew. The sad thing was that the UK production decline has continued even into this year. When I left the UK, I told one young geologist that if she wanted to have a career in the oil business, she was going to have to leave the UK. While that day hasn't come for her yet, it will. No one will pay geologists to manage fields that aren't producing. The above curve is what peak oil looks like for a country--a plateau followed by a gradual decline that is inexorable.

Now that we know what peak oil looks like, lets look at the current global production of both black oil (crude) and Total Liquids (crude plus condensate--a liquid that comes out of natural gas wells which is usually clear).

What we see here is that following the post-911 recession, there is the ramp up of production to supply the increasing demand from China and India. By late 2004, the rate of increase in world crude production (blue curve) slowed, reaching a peak of 74.3 million barrels per day in May 2004, marked by an arrow. The trend from that time has been down, gradually I would admit, but down none the less.

So, why do I call this the peak of world crude production? Isn't it possible that new production will come on line and lift that number above the 74.3 million bbl/day? Possible, barely, probable, no. Why? All the world's biggest fields are in decline, and they produce a large percentage of the world's oil. We saw Saudi Arabia's production, and that represents 10% of world oil. So, we know that 10% of the world's oil in in decline. But the Saudi's are the second largest producer. Russia, the largest producer of oil, is, at best, flat in production now. The U.S. is the third largest producer of oil (something that surprises everyone) and we have been declining in oil production for 30 years. These three countries account for 28% of the world's production, all in decline.

Mexico has the 3rd largest oil field and that one field represents 2/3 of its crude production. It is in decline, plummeting 20% last year. The UK, Norway, Indonesia, Oman and China are all in production declines. The only places on earth that are undergoing significant increases in crude production are Angola, Kazakhstan and Brazil. Kazakhstan will always be limited to the size of the pipeline it has available. Pipelines have fixed capacity.

Given all this, it is hard to see how the future is going to bring forth vast new quantities of daily production.

Another objection: Above I said that peak oil was a plateau followed by a decline. Could we be in the plateau of world production? Yes, that is certainly possible but for the reasons I list above, the current levels of production simply can't be maintained. Annually, the world loses 5 million bbl/day of productive capacity. The curve above shows that we are not adding to world productivity rates even 5 million bbl/day per year of productive capacity since 2005, which would have keep us absolutely flat.

Now, one other thing makes me think that this is the peak of world crude production. The price response in relation to the supply. Usually if price is going to bring forth new supplies from OPEC (who supposedly has all these vast untapped oil fields just waiting to be turned on), it would happen in sharp steps. The Saudi's have not increased production since late 2004 or early 2005. Yet, because the price has gone up from that time, if they had the oil, they could have made lots and lots of money. But they don't seem to be able to take additional advantage of the oil price. In spite of high prices, indeed, increasing prices, no one on earth seems to have the excess capacity sell more oil into this rising price environment. Given the past history of cheating on the part of the OPEC members, the lack of new supplies coming to market must say something important about its availability

Another interesting feature is the total liquids curve (the red curve). This is both black oil plus the clear condensate from natural gas wells. This curve also seems to have peaked, but peaked a year later, in July 2006. Thus, we are 2 years out from peak crude oil, but only one year out from a probable peak liquids.

What are the implications?

The most important thing we need to know is the rate of decline, which of course, we don't know and won't know for a while. We can delimit it a bit. a 1 million bbl/day decline from May 2005 until May 2007 represents approximately a .75% decline per year. Hardly something to worry about right? The first year of UK decline was only about .5%. The second year of decline was 9%, but then, the UK is a much smaller place than the world, so it is unrealistic to expect the world to follow precisely the UK pattern of decline. We can expect the world crude production to decline much faster in the next few years than it is right now. How fast remains to be seen, but even a 5% decline will mean that in 10 years we will be producing only 60% of what we do today! Instead of having 85 million barrels per day of total liquids, we would only have access to 50 million barrels per day.

Driving

Clearly that kind of restriction in oil supply means that either mass transit must come to America as it is in China, or we must only go to work 3 days per week. In 10 years, having only 60% of the oil we have today means 40% less driving for everyone. Going to work only 3 days per week, would mean the destruction of the economy. Most jobs can't be handled across the internet. How does one do the job of grocery store stocker by telecommuting? Even today though, the relatively mild oil prices we have experienced have altered the driving habits of the American public. I sent this chart to a friend last summer. The chart shows the change in mileage driven on US highways from last year. If we drive more this year than last year, the number will be positive; if we drive less, then the number is negative. As you can see, the response to the rise in the price of oil (green curve) has been that for the first time in 27 years Americans are driving less than the previous year. The last time this happened was during the Iranian hostage crisis!

Expect more of this in the future.

Another implication is that automakers shouldn't make gas guzzlers. Those old enough to remember the Iranian hostage crisis, when everyone had to take turns getting gasoline on alternate days, knows a bit of what it will feel like. Back then, people stopped buying big cars. The V8 went out of style in the 1970s; it was too expensive. I expect the Hummer will meet a similar fate.

Suburban sprawl won't work

American cities will need to restructure to be more like European cities, where one can walk to the stores. In Aberdeen, Scotland, most Aberdonians shopped daily because they had tiny refrigerators. But that didn't matter, if they forgot something, they could walk to the store in about the same time it takes me to drive to the store here.

Flying

Flying will become like it was when I was a child--the province of the rich. I did not get on a commercial jet until I was 25 years old. My children grew up with flying and have seen far more of the world than I have at an equivalent age. But, as oil prices rise, fuel costs will bury many airlines. As far as I know, I own no airline stocks either directly or indirectly through mutual funds. They are not going to have a growing clientele as energy costs go up. We have already seen one of the impacts of the energy costs to this sector. Years ago, I was speaking with my wife's brother-in-law who used to work with Boeing. Boeing had made the choice to go energy efficient with their planes, while Airbus had decided to go BIG. I told my wife's brother-in-law that Boeing had made the correct choice. This is from a Business Week web site:

"Instead, the show could highlight a growing list of woes at the company, based in Toulouse, France. On June 1, Airbus acknowledged that the first deliveries of the A380 will be delayed up to six months, from mid-2006 until early 2007, due to unspecified production difficulties. Then Emirates airlines, which had been expected to announce a big order for the A350 at the air show, said it was not ready to make a decision. Airbus sales chief John J. Leahy, who said earlier that he might announce more than 100 orders for the A350 in Paris, now says big orders could come "a week or two after."

Has Airbus lost its mojo? The past few months have been rough. Boeing, after trailing Airbus on orders for the past three years, has racked up 255 orders as of the end of May, compared with only 196 for Airbus. Even more worrisome, Boeing's new 787, which boasts better fuel efficiency thanks to lightweight composite materials and next-generation engine design, is proving a hit with airlines. They have placed orders and commitments for 266 of the jets, while Airbus has yet to announce a major deal for the competing A350. Meanwhile, the A380's order book has been stuck at 154 since last year." Why Airbus is Losing Altitude," June 20, 2005, http://www.businessweek.com/magazine/content/05_25/b3938069_mz054.htm

And a more recent news source notes that Boeing has won 706 orders for its Dreamliner while Airbuss has only 154 for the A350. Energy is king in the airline industry, even if a government run airplane manufacturer thinks they can change the laws, both of the land and of physics.

Food

One percent of world energy use goes to fertilizers. High energy prices will affect fertilizer use. Indeed, we can see that now. This is a plot of inflation adjusted oil price divided by 100 (so it will fit on the same chart) with the barrels of oil equivalent energy of fertilizer applied per acre of wheat. One can see that when oil prices are high, fertilizer use is low; and vice versa.

Few city people know that an acre of wheat has 1.3 million wheat plants--a density hard to achieve if one is throwing seed by hand. Corn is sown at 30,000 plants per acre. Such densities require mechanical sowers. To sow corn at these densities by hand would require 42 hours (5 seconds per seed). This kind of puts into perspective the utility of energy for our tractors. If the price of oil goes up, there will be fewer bushels per acre because of the combined effects of less mechanization and less fertilizer. Now clearly for a while efficiencies will help. People will figure out how to apply fertilizer more effectively; but eventually not having fertilizer will come into play.

I am fond of citing a little known fact I got from a Walter Youngquist article. Mechanization allows a farmer to spend 4 hours per acre and produce 160 bushels of corn per acre. Back in the 19th century, it was 500 hours per acre an 30 bushels of corn per acre. This of course brings an interesting conundrum to those expecting corn-based ethanol to fuel the world. Without petroleum-based fertilizers, there won't be enough corn to feed us much less fuel the world. A five fold drop in corn yields would leave many in the world starving.

It is unlikely that we will be able to have air-shipped strawberries from Argentina in the winter, so food will once again become seasonal, like it was in my childhood before globalization.

Water

Water and food are entirely linked. Without water, many crops won't grow, but we also need water to drink. A few weeks back the Wall Street Journal gave a couple of interesting facts about farming in India.

"Since the 1990s, India has been a major net exporter of rice, shipping nearly 4.5 million tons last year.
"But annual yield increases began to slow over the past decade. Farmers cranked up fertilizer and water use, draining the water table. Many began planting two crops a year, taxing the soil. Punjabi area officials discouraged farmers from planting two crops and in some places outlawed it, but many farmers ignored them."
"I'm doing mischief against the government,' concedes Kanwar Singh, a second rice crop recently on a stretch of flooded land near the northern India city of Karnal. He says he now has to pump water from 300 feet below the surface, compared with 70 feet 10 years ago." 'In a year or two, maybe it will be finished,' he says." Patrick Barta, "Feeding Billions, A Grain at a Time," Wall Street Journal, Saturday/Sunday July 28-29, 2007, p. A10

and

"Lakhbir Singh, 35, this year planted aerobic rice for the first time. He says his costs have tripled over the past decade. His well was about 60 feet deep 10 years ago; now, it's down to 450 feet, and he has to use a special submersible engine to help haul the water to surface. The health of his soil has deteriorated, so he's using more fertilizer." Patrick Barta, "Feeding Billions, A Grain at a Time," Wall Street Journal, Saturday/Sunday July 28-29, 2007, p.A10

One simply MUST have energy to pull that water up from depths of 300 to 450 feet. Without it, there will be no water. Which raises the question, what will these poor guys do when the electricity isn't there to run their pumps?

But this isn't a problem for poor Indian farmers. When the electricity is off, the water pumps, which pump water out of deep wells will not be running. That means that agricultural irrigation will be interrupted. That means that city water supplies won't flow either. Both wells and surface water systems require electricity to move the water from source to your favorite drinking fountain.

Energy source

Another implication is that coal will have to play a larger role in the US energy budget over the near term. We can use coal to make diesel, electricity and thus mitigate, for a while, the coming problems. Coal can be used to manufacture fertilizer and avoid the problems (for a while) cited immediately above. We will use coal or our economy will not function. We will simply have to lose our aversion to coal and the CO2 it produces. I have asked many greens this question: If it comes to a choice between your child freezing in the dark or burning coal, which would you choose. I have yet find one so pure to their principles that they tell me they would let their kid freeze in the dark of a winter night. They all will burn coal to keep warm. Having lived in a society (China) where coal is the major source of energy, the smog is almost unbearable. There were days I could taste the sulfur in my mouth as I walked to work in Beijing. But we are no different than they. Their choice is also one of burn oil or have no heat in the winter or cooked food. The only alternative would be to chop down all the trees (which has almost been done in wide areas of China).

Yesterday there was an article in the Wall Street Journal talking about the coming electricity problems for Texas. Due to the success of the Greens at stopping TXU from building coal-fired power plants, in 3-4 years, Texas will probably start having similar problems to those California is having. California, and now Texas, stupidly decided that we would rather freeze in the dark rather than burn coal. We get 60% of our electricity from fossil fuels, coal, oil and natural gas! The decisions we make today will have immense impacts on your ability to go to work (how is your computer going to function without electricity? Do you really want to be able to drink water from the fountain on your 27th story office? Won't you just love walking those 27 stories each morning to get to work, which will put you in great shape if you don't have a heart attack during that first month of climbing). I suppose deodorant sales will increase in such a situation.

Conclusion

I will finish with personal story from my life overseas. When I lived in the UK, I saw what happens when the oil is shut off. In Sept 2000, the lorry drivers blockaded the refineries. My wife and I were brand new in the UK and driving back from a play in Aberdeen one night, we saw huge lines at the petrol stations. We wondered what was going on, but we drove on home not wanting to be in such long lines anyway. Unfortunately, those people in line, knew that the refineries had been blockaded, I didn't. By the time we realized it, the petrol was gone. That led to many interesting experiences. In one week, the food on the store shelves was gone. By two weeks, police and fire and ambulance were having trouble responding. Farmers were about to have to slaughter chickens because they couldn't get feed after only 2.5 weeks. Construction sites shut down. I learned through that experience that a society has about 3 weeks after the oil is shut off. Food ceases to moveinto the cities.

How can economic growth continue if each day into the future we have less energy than we had the day before??? This is a historic moment in human history. For the first time in 10,000 years, we have less energy than we had yesterday. And that will continue into the foreseeable future.

Precious Metals, Commodities and The Innovation Threat

Source: Yahoo Biz

Innovation is the enemy of commodity investor.

OK, that might be exaggeration, but it does point to a bigger truth. Platinum and palladium markets are trading down today on news that engineers at Nissan Corp. have figured out how to design catalytic converters that use only half as much platinum, palladium and rhodium as existing models. That’s a huge breakthrough and a matter of critical important to platinum investors, because catalytic converters consume 54 percent of the platinum sold each year, according to Standard Chartered PLC (via this Bloomberg story. If Nissan’s new system bears out and everyone switches to it, platinum demand could fall precipitously.

(It may seem odd that the same metal that is coveted for wedding rings also helps scrub soot out of auto exhaust systems, but it’s true; they use diamonds in mining tools and X-ray machines, too.)

Of course, it’s not as if demand for platinum will tumble overnight. The system is as-yet unproven and there are huge legacy investments in machining plants based on the old method. But if platinum prices stay high, this and future innovations will find ways to reduce industrial demand for platinum and related metals. Higher prices increase the premium on innovation and make it economical to investigate alternative methods to achieve the same result.

We are seeing similar developments in the energy industry. Sky-high (and persistently high) oil prices have made it attractive to invest in alternative fuels and alternative sources of crude, such as oil sands, shale oil and more. It has also pushed oil engineers to look in more unusual places, including ultra-deep wells and politically challenging countries.

Similarly, folks are investigating ways to conserve energy, which is being borne out in developments like new hybrid-electric vehicles and efforts to ban the use of incandescent bulbs. (The fact that OPEC has allowed oil prices to remain so high that these efforts are profitable is one of the reasons many people believe OPEC is pumping at maximum capacity; in the past, they have periodically flooded the market with oil as a way of discouraging alternative energy research.)

Nearly all commodities are exposed to innovation/conservation risk, although some more than others. Agricultural commodities are less exposed, as it is difficult to fundamentally replace food; nonetheless, innovation can and will make crop-growing more efficient, find new uses for formerly discarded crops, etc.

Gold’s value is more immune, as gold has no real utility, and its value is tied solely to the fact that it’s gold. A narrowly focused market like palladium is the most exposed, functioning like a company with a single large customer, where things can go horribly wrong in a heartbeat if that one customer gets in trouble.

How do you play this theme as an investor? Well, for starters, it opens up an entirely new platform for commodities related investments. Instead of investing in actual agricultural commodities, you can invest in fertilizer plays or companies like Monsanto. Instead of buying oil futures, you buy deep sea rig companies and developers of photo-voltaic cells. PowerShares actually offers an exchange-traded fund (AMEX: PZD - News) that invests in companies that help other companies operate more efficiently.

Staying within pure play commodities, an alternate approach might be to look for pricing discrepancies between substitutable commodities. For instance, oil is currently much more expensive than natural gas on a per-BTU basis. The reason is that oil is more useful in today’s economy: it’s easier to turn into gas, heating oil and other useful distillates, and it’s easier to transport from one location to another. Assuming oil prices stay high, that pricing gap provides a huge incentive for companies to figure out ways to make natural gas more useful, which could help narrow the BTU spread over time.

Platinum futures were only off marginally in New York trading, but as news of the Nissan innovation spreads, they may face more downward pressure.

The High Costs of Ethanol

Source: The New York Times

Published: September 19, 2007

Backed by the White House, corn-state governors and solid blocks on both sides of Congress’s partisan divide, the politics of biofuels could hardly look sunnier. The economics of the American drive to increase ethanol in the energy supply are more discouraging.

American corn-based ethanol is expensive. And while it can help cut oil imports and provide modest reductions in greenhouse gases compared to conventional gasoline, corn ethanol also carries considerable risks. Even now as Europe and China join the United States in ramping up production, world food prices are rising, threatening misery for the poorest countries.

The European Union has announced that it wants to replace 10 percent of its transport fuel with biofuels by 2020. China is aiming for a 15 percent share. The United States is already on track to exceed Congress’s 2005 goal of doubling the amount of ethanol used in motor fuels to 7.5 billion gallons by 2012. In his State of the Union speech in January, President Bush set a new goal of 35 billion gallons of biofuels by 2017. In June, the Senate raised it to 36 billion gallons by 2022. Of that, Congress said that 15 billion gallons should come from corn and 21 billion from advanced biofuels that are nowhere near commercial production.

The distortions in agricultural production are startling. Corn prices are up about 50 percent from last year, while soybean prices are projected to rise up to 30 percent in the coming year, as farmers have replaced soy with corn in their fields. The increasing cost of animal feed is raising the prices of dairy and poultry products.

The news from the rest of the world is little better. Ethanol production in the United States and other countries, combined with bad weather and rising demand for animal feed in China, has helped push global grain prices to their highest levels in at least a decade. Earlier this year, rising prices of corn imports from the United States triggered mass protests in Mexico. The chief of the United Nations Food and Agriculture Organization has warned that rising food prices around the world have threatened social unrest in developing countries.

A recent report by the Organization for Economic Cooperation and Development, an economic forum of rich nations, called on the United States and other industrialized nations to eliminate subsidies for the production of ethanol which, the report said, is driving up food costs, threatening natural habitats and imposing other environmental costs. “The overall environmental impacts of ethanol and biodiesel can very easily exceed those of petrol and mineral diesel,” it said.

The economics of corn ethanol have never made much sense. Rather than importing cheap Brazilian ethanol made from sugar cane, the United States slaps a tariff of 54 cents a gallon on ethanol from Brazil. Then the government provides a tax break of 51 cents a gallon to American ethanol producers — on top of the generous subsidies that corn growers already receive under the farm program.

Corn-based ethanol also requires a lot of land. An O.E.C.D. report two years ago suggested that replacing 10 percent of America’s motor fuel with biofuels would require about a third of the total cropland devoted to cereals, oilseeds and sugar crops.

Meanwhile, the environmental benefits are modest. A study published last year by scientists at the University of California, Berkeley, estimated that after accounting for the energy used to grow the corn and turn it into ethanol, corn ethanol lowers emissions of greenhouse gases by only 13 percent.

The United States will not meet the dual challenges of reducing global warming and its dependence on foreign suppliers of energy until it manages to reduce energy consumption. That should be its main goal.

There is nothing wrong with developing alternative fuels, and there is high hope among environmentalists and even venture capitalists that more advanced biofuels — like cellulosic ethanol — can eventually play a constructive role in reducing oil dependency and greenhouse gases. What’s wrong is letting politics — the kind that leads to unnecessary subsidies, the invasion of natural landscapes best left alone and soaring food prices that hurt the poor — rather than sound science and sound economics drive America’s energy policy.

Battery-like device could power electric cars

Source: CNN.com

AUSTIN, Texas (AP) -- Millions of inventions pass quietly through the U.S. patent office each year. Patent No. 7,033,406 did, too, until energy insiders spotted six words in the filing that sounded like a death knell for the internal combustion engine.

An Austin-based startup called EEStor promised "technologies for replacement of electrochemical batteries," meaning a motorist could plug in a car for five minutes and drive 500 miles roundtrip between Dallas and Houston without gasoline.

By contrast, some plug-in hybrids on the horizon would require motorists to charge their cars in a wall outlet overnight and promise only 50 miles of gasoline-free commute. And the popular hybrids on the road today still depend heavily on fossil fuels.

"It's a paradigm shift," said Ian Clifford, chief executive of Toronto-based ZENN Motor Co., which has licensed EEStor's invention. "The Achilles' heel to the electric car industry has been energy storage. By all rights, this would make internal combustion engines unnecessary."

Clifford's company bought rights to EEStor's technology in August 2005 and expects EEStor to start shipping the battery replacement later this year for use in ZENN Motor's short-range, low-speed vehicles.

The technology also could help invigorate the renewable-energy sector by providing efficient, lightning-fast storage for solar power, or, on a small scale, a flash-charge for cell phones and laptops.

Skeptics, though, fear the claims stretch the bounds of existing technology to the point of alchemy.

"We've been trying to make this type of thing for 20 years and no one has been able to do it," said Robert Hebner, director of the University of Texas Center for Electromechanics. "Depending on who you believe, they're at or beyond the limit of what is possible."

EEStor's secret ingredient is a material sandwiched between thousands of wafer-thin metal sheets, like a series of foil-and-paper gum wrappers stacked on top of each other. Charged particles stick to the metal sheets and move quickly across EEStor's proprietary material.

The result is an ultracapacitor, a battery-like device that stores and releases energy quickly.

Batteries rely on chemical reactions to store energy but can take hours to charge and release energy. The simplest capacitors found in computers and radios hold less energy but can charge or discharge instantly. Ultracapacitors take the best of both, stacking capacitors to increase capacity while maintaining the speed of simple capacitors.

Hebner said vehicles require bursts of energy to accelerate, a task better suited for capacitors than batteries.

"The idea of getting rid of the batteries and putting in capacitors is to get more power back and get it back faster," Hebner said.

But he said nothing close to EEStor's claim exists today.

For years, EEStor has tried to fly beneath the radar in the competitive industry for alternative energy, content with a phone-book listing and a handful of cryptic press releases.

Yet the speculation and skepticism have continued, fueled by the company's original assertion of making batteries obsolete -- a claim that still resonates loudly for a company that rarely speaks, including declining an interview with The Associated Press.

The deal with ZENN Motor and a $3 million investment by the venture capital group Kleiner Perkins Caufield & Byers, which made big-payoff early bets on companies like Google Inc. and Amazon.com Inc., hint that EEStor may be on the edge of a breakthrough technology, a "game changer" as Clifford put it.

ZENN Motor's public reports show that it so far has invested $3.8 million in and has promised another $1.2 million if the ultracapacitor company meets a third-party testing standard and then delivers a product.

Clifford said his company consulted experts and did a "tremendous amount of due diligence" on EEStor's innovation.

EEStor's founders have a track record. Richard D. Weir and Carl Nelson worked on disk-storage technology at IBM Corp. in the 1990s before forming EEStor in 2001. The two have acquired dozens of patents over two decades.

Neil Dikeman of Jane Capital Partners, an investor in clean technologies, said the nearly $7 million investment in EEStor pales compared with other energy storage endeavors, where investment has averaged $50 million to $100 million.

Yet curiosity is unusually high, Dikeman said, thanks to the investment by a prominent venture capital group and EEStor's secretive nature.

"The EEStor claims are around a process that would be quite revolutionary if they can make it work," Dikeman said.

Previous attempts to improve ultracapacitors have focused on improving the metal sheets by increasing the surface area where charges can attach.

EEStor is instead creating better nonconductive material for use between the metal sheets, using a chemical compound called barium titanate. The question is whether the company can mass-produce it.

ZENN Motor pays EEStor for passing milestones in the production process, and chemical researchers say the strength and functionality of this material is the only thing standing between EEStor and the holy grail of energy-storage technology.

Joseph Perry and the other researchers he oversees at Georgia Tech have used the same material to double the amount of energy a capacitor can hold. Perry says EEstor seems to be claiming an improvement of more than 400-fold, yet increasing a capacitor's retention ability often results in decreased strength of the materials.

"They're not saying a lot about how they're making these things," Perry said. "With these materials (described in the patent), that is a challenging process to carry out in a defect-free fashion."

Perry is not alone in his doubts. An ultracapacitor industry leader, Maxwell Technologies Inc., has kept a wary eye on EEStor's claims and offers a laundry list of things that could go wrong.

Among other things, the ultracapacitors described in EEStor's patent operate at extremely high voltage, 10 times greater than those Maxwell manufactures, and won't work with regular wall outlets, said Maxwell spokesman Mike Sund. He said capacitors could crack while bouncing down the road, or slowly discharge after a dayslong stint in the airport parking lot, leaving the driver stranded.

Until EEStor produces a final product, Perry said he joins energy professionals and enthusiasts alike in waiting to see if the company can own up to its six-word promise and banish the battery to recycling bins around the world.

"I am skeptical but I'd be very happy to be proved wrong," Perry said.

Salt water as fuel? Erie man hopes so

By David Templeton, Pittsburgh Post-Gazette

For obvious reasons, scientists long have thought that salt water couldn't be burned.

So when an Erie man announced he'd ignited salt water with the radio-frequency generator he'd invented, some thought it a was a hoax.

John Kanzius, a Washington County native, tried to desalinate seawater with a generator he developed to treat cancer, and it caused a flash in the test tube.

Within days, he had the salt water in the test tube burning like a candle, as long as it was exposed to radio frequencies.

His discovery has spawned scientific interest in using the world's most abundant substance as clean fuel, among other uses.

Rustum Roy, a Penn State University chemist, held a demonstration last week at the university's Materials Research Laboratory in State College, to confirm what he'd witnessed weeks before in an Erie lab.

"It's true, it works," Dr. Roy said. "Everyone told me, 'Rustum, don't be fooled. He put electrodes in there.' "

But there are no electrodes and no gimmicks, he said.

Dr. Roy said the salt water isn't burning per se, despite appearances. The radio frequency actually weakens bonds holding together the constituents of salt water -- sodium chloride, hydrogen and oxygen -- and releases the hydrogen, which, once ignited, burns continuously when exposed to the RF energy field. Mr. Kanzius said an independent source measured the flame's temperature, which exceeds 3,000 degrees Fahrenheit, reflecting an enormous energy output.

As such, Dr. Roy, a founding member of the Materials Research Laboratory and expert in water structure, said Mr. Kanzius' discovery represents "the most remarkable in water science in 100 years."

But researching its potential will take time and money, he said. One immediate question is energy efficiency: The energy the RF generator uses vs. the energy output from burning hydrogen.

Dr. Roy said he's scheduled to meet tomorrow with U.S. Department of Energy and Department of Defense officials in Washington to discuss the discovery and seek research funding.

Mr. Kanzius said he powered a Stirling, or hot air, engine with salt water. But whether the system can power a car or be used as an efficient fuel will depend on research results.

"We will get our ideas together and check this out and see where it leads," Dr. Roy said. "The potential is huge.

"In the life sciences, the role of water is infinite, and this guy is doing something new in using the most important and most abundant material on the face of the earth."

Mr. Kanzius' discovery was an accident.

He developed the RF generator as a novel cancer treatment. His research in targeting cancer cells with metallic nanoparticles then destroying them with radio-frequency is proceeding at the University of Pittsburgh Medical Center and at the University of Texas' MD Anderson Cancer Center in Houston.

Manuscripts updating the cancer research are in preparation for publication in coming months, Mr. Kanzius said.

While Mr. Kanzius was demonstrating how his generator heated nanoparticles, someone noted condensation inside the test tube and suggested he try using his equipment to desalinate water.

So, Mr. Kanzius said, he put sea water in a test tube, then trained his machine on it, producing an unexpected spark. In time he and laboratory owners struck a match and ignited the water, which continued burning as long as it remained in the radio-frequency field.

During several trials, heat from burning hydrogen grew hot enough to melt the test tube, he said. Dr. Roy's tests on the machine last week provided further evidence that the process is releasing and burning hydrogen from the water. Tests on different water solutions and concentrations produced various temperatures and flame colors.

"This is the most abundant element in the world. It is everywhere," Dr. Roy said of salt water. "Seeing it burn gives me chills."

42.8% Efficiency: A New Record for Solar Cells

Source: Treehugger.com

by Jeremy Elton Jacquot
Los Angeles on 08. 1.07

Narrowly edging out the previous record set by Spectrolab late last year, two scientists at the University of Delaware have just created a new device that can convert 42.8% of the light striking it into electricity. The solar cell, built by Christina Honsberg and Allan Barnett, splits light into three components — high, medium and low energy light — and directs it to several different materials which can then extract electrons out of its photons.

One of the device's key elements is an optical concentrator — a lens-type component that increases the cell's efficiency by directing more sunlight to it than would happen naturally (a boost that contributed in great measure to its record-setting performance). It measures in at just below 1 cm thick, a major improvement over the Spectrolab model which featured a concentrating lens about 1 foot thick. Unlike most concentrators that use a two-axis tracking system to follow the sun, this optical concentrator is also stationary — a major feat.

The Defense Advanced Research Projects Agency (DARPA) — which has been funding this and similar efforts through its Very High Efficiency Solar Cell (VHESC) program — hopes to eventually incorporate this technology into portable solar cell battery chargers for American troops. It will now fund a newly formed DuPont-University of Delaware VHESC Consortium to shift production from a lab-scale model to a full-on manufacturing prototype model.

UPDATE: A reader wanted us to clarify an important point — namely the fact that the concentrator itself doesn't increase the efficiency (it actually increases the power output by intensifying the beam of sunlight), the spectrum splitting optics and solar cells accomplish that.

Ethanol Scam: Ethanol Hurts the Environment And Is One of America's Biggest Political Boondoggles

Source: Rolling Stone

From Issue 1032

JEFF GOODELL
Posted Jul 24, 2007 1:36 PM

The great danger of confronting peak oil and global warming isn't that we will sit on our collective asses and do nothing while civilization collapses, but that we will plunge after "solutions" that will make our problems even worse. Like believing we can replace gasoline with ethanol, the much-hyped biofuel that we make from corn.

Ethanol, of course, is nothing new. American refiners will produce nearly 6 billion gallons of corn ethanol this year, mostly for use as a gasoline additive to make engines burn cleaner. But in June, the Senate all but announced that America's future is going to be powered by biofuels, mandating the production of 36 billion gallons of ethanol by 2022. According to ethanol boosters, this is the beginning of a much larger revolution that could entirely replace our 21-million-barrel-a-day oil addiction. Midwest farmers will get rich, the air will be cleaner, the planet will be cooler, and, best of all, we can tell those greedy sheiks to fuck off. As the king of ethanol hype, Sen. Chuck Grassley of Iowa, put it recently, "Everything about ethanol is good, good, good."

This is not just hype -- it's dangerous, delusional bullshit. Ethanol doesn't burn cleaner than gasoline, nor is it cheaper. Our current ethanol production represents only 3.5 percent of our gasoline consumption -- yet it consumes twenty percent of the entire U.S. corn crop, causing the price of corn to double in the last two years and raising the threat of hunger in the Third World. And the increasing acreage devoted to corn for ethanol means less land for other staple crops, giving farmers in South America an incentive to carve fields out of tropical forests that help to cool the planet and stave off global warming.

So why bother? Because the whole point of corn ethanol is not to solve America's energy crisis, but to generate one of the great political boondoggles of our time. Corn is already the most subsidized crop in America, raking in a total of $51 billion in federal handouts between 1995 and 2005 -- twice as much as wheat subsidies and four times as much as soybeans. Ethanol itself is propped up by hefty subsidies, including a fifty-one-cent-per-gallon tax allowance for refiners. And a study by the International Institute for Sustainable Development found that ethanol subsidies amount to as much as $1.38 per gallon -- about half of ethanol's wholesale market price.

Three factors are driving the ethanol hype. The first is panic: Many energy experts believe that the world's oil supplies have already peaked or will peak within the next decade. The second is election-year politics. With the first vote to be held in Iowa, the largest corn-producing state in the nation, former skeptics like Sens. Hillary Clinton and John McCain now pay tribute to the wonders of ethanol. Earlier this year, Sen. Barack Obama pleased his agricultural backers in Illinois by co-authoring legislation to raise production of biofuels to 60 billion gallons by 2030. A few weeks later, rival Democrat John Edwards, who is staking his campaign on a victory in the Iowa caucus, upped the ante to 65 billion gallons by 2025.

The third factor stoking the ethanol frenzy is the war in Iraq, which has made energy independence a universal political slogan. Unlike coal, another heavily subsidized energy source, ethanol has the added political benefit of elevating the American farmer to national hero. As former CIA director James Woolsey, an outspoken ethanol evangelist, puts it, "American farmers, by making the commitment to grow more corn for ethanol, are at the top of the spear on the war against terrorism." If you love America, how can you not love ethanol?

Ethanol is nothing more than 180-proof grain alcohol. To avoid the prospect of drunks sucking on gas pumps, fuel ethanol is "denatured" with chemical additives (if you drink it, you'll end up dead or, at best, in the hospital). It can be distilled from a variety of plants, including sugar cane and switch- grass. Most vehicles can't run on pure ethanol, but E85, a mix of eighty-five percent ethanol and fifteen percent gasoline, requires only slight engine modifications.

But as a gasoline substitute, ethanol has big problems: Its energy density is one-third less than gasoline, which means you have to burn more of it to get the same amount of power. It also has a nasty tendency to absorb water, so it can't be transported in existing pipelines and must be distributed by truck or rail, which is tremendously inefficient.

Nor is all ethanol created equal. In Brazil, ethanol made from sugar cane has an energy balance of 8-to-1 -- that is, when you add up the fossil fuels used to irrigate, fertilize, grow, transport and refine sugar cane into ethanol, the energy output is eight times higher than the energy inputs. That's a better deal than gasoline, which has an energy balance of 5-to-1. In contrast, the energy balance of corn ethanol is only 1.3-to-1 - making it practically worthless as an energy source. "Corn ethanol is essentially a way of recycling natural gas," says Robert Rapier, an oil-industry engineer who runs the R-Squared Energy Blog.

The ethanol boondoggle is largely a tribute to the political muscle of a single company: agribusiness giant Archer Daniels Midland. In the 1970s, looking for new ways to profit from corn, ADM began pushing ethanol as a fuel additive. By the early 1980s, ADM was producing 175 million gallons of ethanol a year. The company's then-chairman, Dwayne Andreas, struck up a close relationship with Sen. Bob Dole of Kansas, a.k.a. "Senator Ethanol." During the 1992 election, ADM gave $1 million to Dole and his friends in the GOP (compared with $455,000 to the Democrats). In return, Dole helped the company secure billions of dollars in subsidies and tax breaks. In 1995, the conservative Cato Institute, estimating that nearly half of ADM's profits came from products either subsidized or protected by the federal government, called the company "the most prominent recipient of corporate welfare in recent U.S. history."

Today, ADM is the leading producer of ethanol, supplying more than 1 billion gallons of the fuel additive last year. Ethanol is propped up by more than 200 tax breaks and subsidies worth at least $5.5 billion a year. And ADM continues to give back: Since 2000, the company has contributed $3.7 million to state and federal politicians.

The Iraq War has also been a boon for ADM and other ethanol producers. The Energy Policy Act of 2005, which was pushed by Corn Belt politicians, mandated the consumption of 7.5 billion gallons of biofuels by 2012. After Democrats took over Congress last year, they too vowed to "do something" about America's addiction to foreign oil. By the time Sen. Jeff Bingaman, chair of the Committee on Energy and Natural Resources, proposed new energy legislation this spring, the only real question was how big the ethanol mandate would be. According to one lobbyist, 36 billion gallons became "the Goldilocks number -- not too big to be impractical, not too small to satisfy corn growers."

Under the Senate bill, only 15 billion gallons of ethanol will come from corn, in part because even corn growers admit that turning more grain into fuel would disrupt global food supplies. The remaining 21 billion gallons will have to come from advanced biofuels, most of which are currently brewed only in small-scale lab experiments. "It's like trying to solve a traffic problem by mandating hovercraft," says Dave Juday, an independent commodities consultant. "Except we don't have hovercraft."

The most seductive myth about ethanol is that it will free us from our dependence on foreign oil. But even if ethanol producers manage to hit the mandate of 36 billion gallons of ethanol by 2022, that will replace a paltry 1.5 million barrels of oil per day -- only seven percent of current oil needs. Even if the entire U.S. corn crop were used to make ethanol, the fuel would replace only twelve percent of current gasoline use.

Another misconception is that ethanol is green. In fact, corn production depends on huge amounts of fossil fuel -- not just the diesel needed to plow fields and transport crops, but also the vast quantities of natural gas used to produce fertilizers. Runoff from industrial-scale cornfields also silts up the Mississippi River and creates a vast dead zone in the Gulf of Mexico every summer. What's more, when corn ethanol is burned in vehicles, it is as dirty as conventional gasoline and does little to solve global warming: E85 reduces carbon dioxide emissions by a modest fifteen percent at best, while fueling the destruction of tropical forests.

But the biggest problem with ethanol is that it steals vast swaths of land that might be better used for growing food. In a recent article in Foreign Affairs titled "How Biofuels Could Starve the Poor," University of Minnesota economists C. Ford Runge and Benjamin Senauer point out that filling the gas tank of an SUV with pure ethanol requires more than 450 pounds of corn -- roughly enough calories to feed one person for a year.

Thanks in large part to the ethanol craze, the price of beef, poultry and pork in the United States rose more than three percent during the first five months of this year. In some parts of the country, hog farmers now find it cheaper to fatten their animals on trail mix, french fries and chocolate bars. And since America provides two-thirds of all global corn exports, the impact is being felt around the world. In Mexico, tortilla prices have jumped sixty percent, leading to food riots. In Europe, butter prices have spiked forty percent, and pork prices in China are up twenty percent. By 2025, according to Runge and Senauer, rising food prices caused by the demand for ethanol and other biofuels could cause as many as 600 million more people to go hungry worldwide.

Despite the serious drawbacks of ethanol, some technological visionaries believe that the fuel can be done right. "Corn ethanol is just a platform, the first step in a much larger transition we are undergoing from a hydrocarbon-based economy to a carbohydrate-based economy," says Vinod Khosla, a pioneering venture capitalist in Silicon Valley. Next-generation corn- ethanol plants, he argues, will be much more efficient and environmentally friendly. He points to a company called E3 BioFuels that just opened an ethanol plant in Mead, Nebraska. The facility runs largely on biogas made from cow manure, and feeds leftover grain back to the cows, making it a "closed-loop system" -- one that requires very few fossil fuels to create ethanol.

Khosla is even higher on the prospects for cellulosic ethanol, a biofuel that can be made from almost any plant matter, including wood waste and perennial grasses like miscanthus and switchgrass. Like other high-tech ethanol evangelists, Khosla imagines a future in which such so-called "energy crops" are fed into giant refineries that use genetically engineered enzymes to break down the cellulose in plants and create fuel for a fraction of the cost of today's gasoline. Among other virtues, cellulosic ethanol would not cut into the global food supply (nobody eats miscanthus or switchgrass), and it could significantly cut global-warming pollution. Even more important, it could provide a gateway to a much larger biotech revolution, including synthetic microbes that could one day be engineered to gobble up carbon dioxide or other pollutants.

Unfortunately, no commercial-scale cellulosic ethanol plants exist today. In one venture backed by Khosla, a $225 million plant in central Georgia is currently being built to make ethanol out of wood chips. Mitch Mandich, a former Apple Computer executive who is now the CEO of the operation, calls it "the beginning of a real transformation in the way we think about energy in America."

Maybe. But oil-industry engineer Robert Rapier, who has spent years studying cellulosic ethanol, says that the difference between ethanol from corn and ethanol from cellulose is "like the difference between traveling to the moon and traveling to Mars." And even if the engineering hurdles can be overcome, there's still the problem of land use: According to Rapier, replacing fifty percent of our current gasoline consumption with cellulosic ethanol would consume thirteen percent of the land in the United States - about seven times the land currently utilized for corn production.

Increasing the production of cellulosic ethanol will also require solving huge logistical problems, including delivering vast quantities of feedstock to production plants. According to one plant manager in the Midwest, fueling an ethanol plant with switchgrass would require delivering a semi-truckload of the grass every six minutes, twenty-four hours a day. Finally, there is the challenge of wrestling the future away from Big Corn. "It's pretty clear to me that the corn guys will use all their lobbying muscle and political power to stall, thwart and sidetrack this revolution," says economist C. Ford Runge.

In the end, the ethanol boom is another manifestation of America's blind faith that technology will solve all our problems. Thirty years ago, nuclear power was the answer. Then it was hydrogen. Biofuels may work out better, especially if mandates are coupled with tough caps on greenhouse-gas emissions. Still, biofuels are, at best, a huge gamble. They may help cushion the fall when cheap oil vanishes, but if we rely on ethanol to save the day, we could soon find ourselves forced to make a choice between feeding our SUVs and feeding children in the Third World. And we all know how that decision will go.

We Must Imagine a Future Without Cars

Source: AlterNet

By James Howard Kunstler
Posted April 4, 2007

The following is James Howard Kunstler' recent speech to the Commonwealth Club of California. An audio stream of the speech is available.

Two years ago in my book The Long Emergency I wrote that our nation was sleepwalking into an era of unprecedented hardship and disorder -- largely due to the end of reliably cheap and abundant oil. We're still blindly following that path into a dangerous future, lost in dark raptures of infotainment, diverted by inane preoccupations with sex and celebrity, made frantic by incessant motoring.

The coming age of energy scarcity will change everything about how we live in this country. It will ignite more desperate contests between nations for the remaining oil and natural gas around the world. It will alter the fundamental terms of industrial economies. It will ramify and amplify many of the problems presented by climate change. It will require us to behave differently. But we are not paying attention.

As the American public continues sleepwalking into a future of energy scarcity, climate change, and geopolitical turmoil, we have also continued dreaming. Our collective dream is one of those super-vivid ones people have just before awakening, as the fantastic transports of the unconscious begin to merge with the demands of waking reality. The dream is a particularly American dream on an American theme: how to keep all the cars running by some other means than gasoline. We'll run them on ethanol! We'll run them on biodiesel, on synthesized coal liquids, on hydrogen, on methane gas, on electricity, on used French-fry oil... !

The dream goes around in fevered circles as each gasoline-replacement is examined and found to be inadequate. But the wish to keep the cars going is so powerful that round and round the dream goes. Ethanol! Biodiesel! Coal Liquids. ...

And a harsh reality indeed awaits us as the full scope of the permanent energy crisis unfolds. The global oil production peak is not a cult theory, it's a fact. The earth does not have a creamy nougat center of petroleum. The supply in finite, and we have ample evidence that all-time global production has peaked.

Of course, the issue is not about running out of oil, and never has been. There will always be some oil left underground -- it just might take more than a barrel-of-oil's worth of energy to pump each barrel out, so it won't be worth doing.

The issue is not about running out -- it's about what happens when you head over the all-time production peak down the slippery slope of depletion. And what happens is that the complex systems we depend on for everyday life in advanced societies begin to falter, wobble, and fail -- and the failures in each system will in turn weaken the others. By complex systems I mean the way we produce our food, the way we conduct manufacture and trade, the way we operate banking and finance, the way we move people and things from one place to another, and the way we inhabit the landscape.

I'll try not to dwell excessively on the statistics since I am more concerned here with the implications for everyday life in our nation. But it is probably helpful to understand a few of the numbers.

Oil production in the US peaked in 1970. We're now producing about half of what we did then, and our own production continues to run down steadily at the rate of a few percentage points of recoverable reserves each year. It adds up. In 1970, we were producing about 10 million barrels a day. Now we're down to less than five -- and we consume over 20 million barrels a day. We have compensated for that since 1970 by importing oil from other nations. Today we import about two-thirds of all the oil we use. Today, the world is consuming all the oil it can produce. As global production passes its own peak, the world will not be able to compensate for its shortfall by importing oil from other planets.

Nor is there any real likelihood that new discoveries will be adequate to compensate. Discovery precedes production, of course, because you can't pump oil that you haven't discovered. Discovery of oil in the US peaked in the 1930s -- and production started declining roughly 30 years later. Discovery of oil peaked worldwide in the 1960s, and now the signs suggest the world has peaked. Discovery of new oil worldwide in recent years has amounted to a tiny fraction of replacement levels. In fact, we may be burning more oil just in our exploration efforts than we will get from the oil we're discovering.

The oil industry has been dominated by what are called supergiant fields. The four reigning supergiant fields of oil our time were discovered decades ago and are now in decline. The Burgan field of Kuwait, the Daqing of China, Cantarell of Mexico, and Ghawar of Saudi Arabia. Together in recent decades they were responsible for 14 percent of the world's oil production, and they are now in decline. All except Ghawar of Saudi Arabia have been declared officially past peak by their own governments and Ghawar is showing clear signs of trouble -- though Aramco itself won't say so. Ghawar has provided 60 percent of Saudi Arabia's production. Saudi Arabia's total production is down 8 percent in the year past, despite a massive increase in drilling rigs, and the incentive of high prices.

Last year, the Mexican national oil company, Pemex, declared its supergiant field, Cantarell, to be officially past peak and in decline. As in the case with Ghawar and Saudi Arabia, Cantarell has been responsible for 60 percent of Mexico's oil production. Cantarell is now crashing at an official decline rate of at least 15 percent a year -- perhaps steeper. Mexico has been our No. 3 source of oil imports (after Canada and Saudi Arabia). The crash of Cantarell means in just a few years Mexico, our No. 3 source of imports, will have no surplus oil to sell to the US. It also means that the Mexican government will be strapped for operating revenue -- and you can draw your own conclusions about the political implications.

The North Sea and Alaska's North Slope were some of the last great discoveries of the oil era. Plentiful North Sea and Alaskan production took away OPEC's leverage over the oil markets. This led to the oil glut of the 1990s, driving oil prices down finally to $10 a barrel. It is also what induced the American public to fall asleep on energy issues. It seemed as if cheap oil was here to stay. Forever.

Both The North Sea and Alaska are now past peak and in depletion. Prudhoe Bay proved to be Alaska's only super giant oil field. Several other key fields were discovered. None were even 1/6th the size of Prudhoe Bay.

North Sea oil was produced using the latest-and-greatest new technology for drilling and guess what: it only allowed the region to be drained more rapidly and efficiently. Now 57 of Norway's 69 oil fields are past peak and the average post-peak decline rates average 17 percent a year. The UK's share of the North Sea has declined to the extent that England is now a net energy importer.

Russia, despite current high levels of post-Soviet-era production, peaked in the 1980s, and may now be past 70 percent of its ultimate recoverable reserves. Iran is past peak. Indonesia, an OPEC member, is so far past peak it became a net oil importer last year. Venezuela is past peak. Iraq and Nigeria are consumed by political insurrection. The companies developing Canada's tar sands have announced this past year that their costs will double original estimates -- in other words, whatever comes out of the ground there will be very expensive.

Meanwhile, in the background, completely ignored by the US media, an additional problem is developing on the oil scene. Net world production is going down by just under 3 percent a year, but total exports from the top ten exporters are going down at an even steeper rate. Geologist Jeffrey Brown, among the excellent technicians at TheOilDrum.com website, writes that the top ten exporters are showing a net export decline rate of 7 percent the past year, trending toward a 50 percent export decline over the coming ten years. Why? Because on top of production decline rates, nations like Saudi Arabia, Iran, and Venezuela are using more of their own oil at home with rising populations and more automobiles.

A few additional background items. Most of the easy-to-get, light and sweet crude oil is gone. We got that out of the ground in the run-up to peak [oil]. We found that high quality oil in temperate places onshore, like Texas, where it was easy and pleasant to work, and the stuff was relatively close to the surface. The remaining oil is, each year, proportionally made up more of heavy and sour crudes that are hard to refine and yield less gasoline. Most of the refinery capacity in the world cannot process these heavy and sour crudes and there is no world-class industrial effort to build new ones -- and on top of that, existing world refinery infrastructure is old and rusty. Finally, most of the remaining oil in the world exists either in geographically forbidding places where it is extremely difficult and expensive to work, like deep water out in the ocean or in frozen regions, or else it belongs to people who are indisposed to be friendly to us.

The natural gas situation is at least equally ominous, with some differences in the technical details -- and by the way, I'm referring here not to gasoline but to methane gas (CH4), the stuff we run in kitchen stoves and home furnaces. Natural gas doesn't deplete slowly like oil, following a predictable bell curve pattern; it simply stops coming out of the ground very suddenly, and then that particular gas well is played out. You get your gas from the continent you're on. Natural gas is moved to customers in the US, Canada, and Mexico in an extensive pipeline network. To import natural gas from overseas, it has to be liquefied, loaded in a special kind of expensive-to-build-and-operate tanker ship, and then offloaded at specialized marine terminal, all adding layers of cost. The process also obviously affords us poor control over not-always-friendly foreign suppliers.

Half the homes in America are heated with gas furnaces and about 16 percent of our electricity is made with it. Industry uses natural gas as the main ingredient in fertilizer, plastics, ink, glue, paint, laundry detergent, insect repellents and many other common household necessities. Synthetic rubber and man-made fibers like nylon could not be made without the chemicals derived from natural gas. In North America, natural gas production peaked in 1973. We are drilling as fast as we can to keep the air conditioners and furnaces running.

That's the background on our energy predicament. Against this background is the whole question of how we live in the United States. I wrote three books previously about the fiasco of suburbia. There are many ways of describing it, but lately I refer to it as the greatest misallocation of resources in the history of the world. Why? Because it is a living arrangement with no future. Why doesn't it have a future? Because it was designed to run on cheap oil and gas, and in just a few years we won't have those things anymore.

Having made these choices, we are now hobbled by a tragic psychology of previous investment -- that is, having poured so much of our late-20th century wealth into this living arrangement -- this Happy Motoring utopia -- we can't imagine letting go of it, or substantially reforming it.

We have compounded the problem lately by making the building of suburban sprawl the basis of our economy. Insidiously, we have replaced America's manufacturing capacity with an economy based on building evermore suburban houses and the accessories and furnishings that go with them -- the highway strips, the big box shopping pods, et cetera -- meaning that our economy is now largely based on building more and more stuff with no future -- on a continued misallocation of resources. Roughly 40 percent of the new jobs created between 2001 last year were in housing bubble related fields -- the builders, the real estate agents, the mortgage brokers, the installers of granite countertops. If you subtracted the housing bubble from the rest of the economy in recent years, there wouldn't be much left besides hair-styling, fried chicken, and open heart surgery. Much of this housing bubble itself was promulgated by an equally unprecedented lapse in standards and norms of finance -- a tragedy-in-the-making that has now begun to unwind. What are we going to do about our extreme oil dependence and the living arrangement that goes with it?

There's a widespread wish across America these days that some combination of alternative fuels will rescue us; will allow us to continue enjoying by some other means what has been called "the non-negotiable American way of life." The wish is perhaps understandable given the psychology of previous investment.

But the truth is that no combination of alternative fuels or systems for using them will allow us to continue running America the way we have been, or even a substantial fraction of it. We are not going to run Wal Mart, Walt Disney World, Monsanto, and the interstate highway system on any combination of solar or wind energy, hydrogen, nuclear, ethanol, tar sands, oil shale, methane hydrates, thermal depolymerization, zero-point energy, used french-fry oil, or anything else you can name. We will desperately use many of these things in many ways, but we are likely to be disappointed by what they can actually do for us, particularly in terms of scale -- apart from the fact that most or all of them are probably net energy losers in economic terms.

For instance, we are much more likely to use wind power on a household or neighborhood basis rather than in deployments of Godzilla-sized turbines in so-called wind farms.

The key to understanding what we face is that we have to comprehensively make other arrangements for all the normal activities of everyday life. It is a long, detailed "to do" list that we can't afford to ignore. The public discussion of these issues is impressively incoherent. This failure of the collective imagination is reflected in the especially poor job being done by the mainstream media covering this story -- in particular, The New York Times, which does little besides publish feel-good press releases from Cambridge Energy Research Associates, the oil industry's chief public relations consultant.

These days, the only aspect of these issues that we are willing to talk about at all is how we might keep all our cars running by other means. We have to get beyond this obsession with running the cars by other means. The future is not just about motoring. We have to make other arrangements comprehensively for all the major activities of daily life in this nation.

We'll have to grow our food differently. The ADM/Monsanto/Cargill model of industrial-scale agribusiness will not survive the discontinuities of the Long Emergency -- the system of pouring oil-and-gas-based fertilizers and herbicides on the ground to grow all the cheez doodles and hamburgers. As oil and gas deplete, we will be left with sterile soils and farming organized at an unworkable scale. Many lives will depend on our ability to fix this.

We will find out the hard way that we can't afford to dedicate our crop lands to growing grains and soybeans for ethanol and biodiesel. A Pennsylvania farmer put it this way to me last month: "It looks like we're going to take the last six inches of Midwest topsoil and burn it in our gas tanks." The disruptions to world grain supplies by the ethanol mania are just beginning to thunder through the system. Last months there were riots in Mexico City because so much Mexican corn is now being already being diverted to American ethanol production that poor people living on the economic margins cannot afford to pay for their food staples.

You can see, by the way, how this is a tragic extension of our obsession with running all the cars.

In the years ahead, farming will come back much closer to the center of American economic life. It will necessarily have to be done more locally, at a smaller-and-finer scale, and will require more human attention. Many of the value-added activities associated with farming -- making products like cheese, wine, oils -- will also have to be done much more locally. This situation presents excellent business and vocational opportunities for America's young people. It also presents huge problems in land-use reform. Not to mention the fact that the knowledge and skill for doing these things has to be painstakingly retrieved from the dumpster of history.

We're going to have to move people and things from place to place differently. It is imperative that we restore the US passenger railroad system. No other project we could do right away would have such a positive impact on our oil consumption. We used to have a railroad system that was the envy of the world. Now we have a system that the Bulgarians would be ashamed of.

The infrastructure for this great task is lying out there rusting in the rain. This project would put scores of thousands of people to work at meaningful jobs, at every level, from labor to management. It would benefit all ranks of society. Fixing the US passenger rail system doesn't require any great technological leaps into the unknown. The technology is thoroughly understood. The fact that from end-to-end of the political spectrum there is no public discussion about fixing the US passenger rail system shows how un-serious we are.

There's another compelling reason we should undertake the great project of repairing the US passenger rail system: it is something that would restore our confidence, a way we could demonstrate to ourselves that we are competent and capable of meeting the difficult challenges of this energy-scarce future. ... And it might inspire us to get on with the other great tasks that we will have to face.

By the way, it is important that we electrify our railroad system. All the other advanced nations have electric rail systems which allow them to run on something other than fossil fuel or to control the source point of the carbon emissions and pollution in the case of coal-fired power generation. Electric motors are far simpler and way more efficient even than diesel engines. The US was well underway with the project of electrifying our railroad system, but we just gave up after the Second World War as we directed all our investment to the interstate highway system instead.

We're going to have to move things by boat. But we've just finished a 50-year effort in taking apart most of the infrastructure for maritime trade in America. Our harbors and riverfronts have been almost completely de-activated. The public now thinks that harbors and riverfronts should only be used for condo sites, parks, bikeways, band shells and festival marketplaces. Guess what: We're going to have to put back the piers and warehouses and even the crummy accommodations for sailors.

We're going to have to move a lot more stuff by water or our ability to do commerce will suffer. Meanwhile, if we use trucks, it will be for the very last local increment of the journey. Leaders in business and municipal politics will have to wrap their minds around this new reality.

We are probably in the twilight of Happy Motoring -- as we have known it. The automobile will be a diminished presence in our lives. I'm not saying that cars will disappear, but it will become self-evident that our extreme dependency will have to end. It is possible, but not likely, that affordable electric cars will come on the market before we get into serious trouble with oil. More likely, we'll be facing an entirely new political problem with cars as motoring becomes increasingly only something that the economic elite can enjoy.

For decades, motoring has been absolutely democratic. Everybody from the lowliest hamburger flipper to the richest Microsoft millionaire could participate in the American motoring program. Right now, let's say six percent of adults in this nation can't drive, for one reason or another: They're blind, too old, too poor, et cetera. What if that number rose to 13 percent, or 26 percent of Americans because either the price of fuel or the cost of a vehicle rose beyond their means. Do you suppose that a whole new mood of grievance and resentment might arise against those who were still driving cars? And how would the large new class of non-drivers feel about paying taxes to maintain the very expensive interstate highway systems?

Back to the task list:

We're going to have to make other arrangements for commerce and manufacturing. The national chain discount stores that took over American retail in recent decades will not survive the discontinuities of the Long Emergency. Their business equations and methods of operations will fail, in particular their remorseless cancer-like drive toward replication and expansion. They will lack the resilience to adapt due to their gigantic scale of operations -- a scale that will no longer be appropriate to the contracting available energy "nutrients."

The so-called "warehouse on wheels" composed of thousands of trucks circulating incessantly around the interstate highways will not work economically in a new era of scarcer and expensive oil. Not to mention the 12,000-mile supply line to the factories of Asia which we have tragically come to depend on for so many of our household goods.

We have to check all our assumptions at the door about how things will work in the years ahead. Lately, thanks to Tom Friedman and other cheerleaders for the global economy, we've adopted the notion that globalism is a permanent condition of life. I think we will be disappointed to learn the truth -- that globalism was a set of transient economic relations made possible at a particular time by very special conditions, namely half a century of cheap energy and half a century of relative peace between the great powers.

Those conditions are about to end, and with them, I predict, will go many of the far-flung economic relations that we've come to rely on. When the US and China are contesting for the world's remaining oil resources, do you think it's possible that our trade relations might be affected? These are things we had better be prepared to think about it. China has way outstripped its own dwindling oil supply. China has gone all over the world in recent years systematically making contracts for future delivery of oil with other nations, including Canada, as that nation ramps up production of the tar sands in Alberta.

I want to remind you that there is such a thing as the Monroe Doctrine, an American foreign policy position that essentially forbids nations outside the western hemisphere from intruding in or exploiting affairs in this part of the world. It may be an old and perhaps an arrogant policy -- but I predict the time will come when the United States will invoke it in order to preserve our access to Canadian oil supplies. And if-and-when that occurs, what do you suppose that will mean to our trade relations with China? How many plastic wading pools and salad shooters will Wal-Mart be ordering then?

These are the kinds of things we are not thinking about at all, and which leave us woefully unprepared to face a very uncertain future.

Getting back to retail trade in the US -- it is important to recognize the damage that the national discount chain stores have already done in systematically destroying local commercial economies. If you travel around the main street towns of this nation, as I do, you see places in Pennsylvania, and Michigan, and Alabama, and Oklahoma, and Connecticut, and in my region of the upper Hudson Valley in New York that look like former soviet backwaters. The destruction, the abandonment and desolation in the fabric of our towns is just out of this world.

This era of chain store supremacy will not continue far into the future, and as it wobbles and falls we will be faced with a tremendous task of rebuilding the fine-grained, multi-layered local networks of economic interdependency that the chain stores destroyed. As that rebuilding occurs we will restore social roles as well as economic roles that have long been absent in our home places.

In destroying local retail infrastructures, the chain stores wiped out a whole mercantile middle class. These were the people ran local businesses, who sat on the library and hospital boards, who sponsored the little league baseball, who employed their neighbors and had to behave decently toward them, as well as treating their neighbors decently in matters of trade. They were people who uniformly had to take care of at least two buildings in town -- the place where they did business and the place where they lived. These were the people who were the caretakers of our communities, and the extermination of this class of citizens has been devastating.

We don't know how we are going to make things again in America, for instance, ordinary household products. We're not going to re-live the 20th century, when the US was on a great upswing of energy resources and we made everything for ourselves from toasters to record players. Where I live, in the upper Hudson and Mohawk Valley region of New York, most of the factories have actually been knocked down in the past 20 years. The water power is still there in many of these places, but the buildings are gone. Among all our other wishes, there is a wish that we will innovate stunning new methods for making things, such as nanotechnology. I'd repeat that we'd better check all our assumptions at the door and that we are liable to be disappointed by what these wishes will eventually lead to.

I think the truth is, we are going to have fewer things to buy. The Blue-Light-Special retail orgy of recent decades will fade into history, and shopping will retreat into the background of daily life. Consuming things will not be our sole reason for living.

The role of finance as we know it today will be severely challenged by the Long Emergency. Declining energy supplies have one particular grave implication for industrial societies: that they can no longer take for granted the 3 to 7 percent annual growth in gross domestic product that has been assumed to be normal throughout recent history. In fact, the energy picture -- the dwindling of a particular, extraordinary, one-time, very special resource -- implies a general contraction of productive activity.

Our expectations for growth are vested in tradable paper certificates -- currencies, stocks, bonds, and other instruments that represent our confidence that society will produce more wealth, and that this increase can be enjoyed in the form of profits and dividends. What happens when that consensus about reliable increase falls apart? What happens to the entire edifice of finance when these abstract certificates are no longer backed by the faith of people who have been trading them?

We can see the beginning of this process right now in the unwinding of the home mortgage sector. This recent experiment in the abolition of moral hazard, in the suspension of norms-and-standards in lending, in the fobbing off of risk, is climaxing in one of the great debacles of modern economics. It was based on the idea that immense numbers of promises for future payment could be bundled into bonds, resold, and parlayed to leverage evermore abstract casino-like bets masquerading as investments. This is anything but investment in future productive activity.

It is now being discovered that at the foundation of all this jive-finance activity lie bundles of broken promises, "non-performing loans," as they're called. It remains to be seen how this mortgage-and-housing bubble fiasco will play out, but I think it will be one of the major events leading to an overall loss of presumed wealth for American society. And is likely, as well, to infect the jury-rigged structures of global finance to a disastrous degree.

The key to all our everyday activities in the future is scale. We will probably have to live more locally than has been the case in recent decades. I think we can state categorically that anything organized on the gigantic scale, whether it is an agricultural system, or a finance system, or a corporation, or a chain of stores, or a school, or a government, is going to run into trouble.

School is another item on our "to do" list of things that we have to make other arrangements for. The gigantic centralized public school systems all over America that depend on the massive fleets of yellow school buses for collecting the students every morning around the 50-mile-radius 'pupil sheds' -- this way of doing things will probably encounter failure. Not to mention that we used the same kind of sprawling, one-story, flat-roofed buildings in Florida as in Minnesota -- and given the situation with natural gas we'll have trouble heating these buildings in the colder states. Of course there are plenty of reasons to suspect that schools this large, designed like medium security prisons, are not optimum settings for learning even if oil and gas were plentiful.

Complicating the issue is the fact that our school systems are at the center of the psychology of previous investment. We have put so much of our collective wealth in these sprawling, oversized, vehicle-dependent institutions -- with all their fabulous amenities of swimming pools, video labs, and free parking -- that it will be very difficult for us to let go of them -- even after it is self-evident that they are no longer working. What will replace our giant centralized public schools? School districts will be starved for cash in the Long Emergency. I doubt that we will be able to replace the centralized schools with a whole new system of smaller buildings distributed more equitably around the places where people live. If anything, I suppose a replacement may arise out of home schooling, especially as home schools aggregate into larger neighborhood units so that every parent doesn't have to duplicate the vocational role of teacher (and of course not all parents would even be capable of acting in that role).

The destiny of higher education ought to be especially troubling. The giant universities are exactly the kinds of institutions that will prove unwieldy and unsupportable in the Long Emergency. College will cease to be the mass consumer activity it became in the cheap energy heyday. If it survives at all, it is likely to be -- as earlier in history -- an activity for a much smaller economic elite.

The question of class relations per se will be affected by our energy situation, since it is necessarily linked to our economy. The Long Emergency is going to produce a lot of economic losers -- a whole new group I call the formerly middle class. They will lose jobs, vocations, and incomes that they will never get back. They are going to be full of grievance, anger, resentment, and bewilderment at the loss of their entitlements to the "non-negotiable" American way of life, including home ownership and affordable happy motoring. They are likely to express these feelings politically. We will be lucky if they do not turn to demagogues who promise to mount one sort of campaign or another to restore the entitlements of suburbia.

Such a campaign would be an enormous exercise in futility and a gross waste of our scarce remaining resources. But it is the kind of thing that happens when a society comes under extreme stress, and we had better be prepared for it. Social friction may also be prompted as agriculture comes closer to the center of our economic life, and we're faced with conflict between those who retain wealth in productive land and those who must resort to working in agriculture to make a living. In history, this typically sets the stage for the radical redistribution of property, seizure of land, in short, for political revolution. It could happen here. We are certain to experience epochal demographic shifts in any case. The 200-year-long trend of people leaving the rural places and the small towns to go to the big cities will very likely go into reverse.

Our hyper-gigantic cities and so-called metroplexes are a pure product of the 200-year-long upward arc of cheap energy. Like other things of gigantic scale, our cities will get into trouble. They are going to contract substantially. The cities that are composed overwhelmingly of suburban fabric will be most susceptible to failure. Orlando, Houston, Atlanta. The cities that are overburdened with skyscrapers will face an additional layer of trouble -- the skyscraper, like the mega-city, was a product of cheap energy, and we are going to have trouble running them, especially heating them without cheap natural gas.

As our cities contract, I think they will re-densify at their centers and around their waterfronts, if they are located favorably on water, and depending on how (or if) rising ocean levels might affect them. The process of contraction in our cities is likely to be difficult, disorderly and unequal. Some cities will do better than others. In my opinion, Phoenix and Tucson will be substantially depopulated. They will face additional problems with their ability to produce food locally and with water.

In Las Vegas, the excitement will be over. That will be a good thing since it has become the holy shrine of America's new chief religion: the worship of unearned riches -- based on the belief that it is possible to get something for nothing -- a belief that underlies, by the way, a great deal of the delusional thinking abroad in this land about the ability of alternative fuels and energy schemes to rescue our current mode of living.

It is hard to be optimistic about the destiny of our suburbs. My referring to them as the greatest misallocation of resources in the history of the world pretty much says it all. There will be a wish to rescue them, of course, but it is unlikely to go beyond the wishing stage. We will be a less affluent society in the years ahead than we were when we built the suburbs in the first place, and we will have fewer resources to fix them or retrofit them. The Jolly Green Giant is not going to come and move the houses closer to the shopping -- to undo the vast absurdities of single-use-zoning.

We could reform our codes and regulations which have virtually mandated a suburban sprawl outcome in every American locality -- but it's a little late for that. The horse is out of the barn on that one. And anyway, I believe the mortgage-and-housing bubble fiasco will mark the end of the whole project of suburbanization per se. I don't believe the production home builders will ever recover from it in our lifetimes; we certainly don't need a single additional WalMart or fried food joint; and the energy problems we face will eventually overcome all our wishes to keep that system going, whether we like it or not.

Realistically, I think we will have to return to a set of traditional ways of inhabiting the terrain -- towns, smaller-scaled cities composed of walkable neighborhoods, and a productive rural landscape with more of a human presence than we see in today's countryside. We have thousands of smaller towns and cities waiting to be re-inhabited and re-activated. Most of them occupy geographically important or valuable sites, especially the ones near fresh running water.

For the past two decades I have been associated with the New Urbanist movement. The New Urbanists were architects, planners, and developers who recognized the tremendous weaknesses and liabilities of the suburban pattern and have been campaigning to reform the way we build things in this country. Their methods are consistent with what we are going to need in the decades ahead to refashion human habitats that have a future and which are worth caring about.

The great achievement of the New Urbanists was not in the projects and new towns that they designed and caused to get built in recent years, but in their heroic act of retrieving lost knowledge from the dumpster of history -- a whole body of principles, methods, and skills necessary to design places worth living in. This was knowledge and principle that we had thrown away in our mad rush to become a drive-in utopia. We threw it away thinking that we could replace urban design and artistry with mere traffic engineering and statistical analysis. The result of that is now visible for all to see in the tragic landscape of the highway strips and the single-income housing pods. What we managed to do was build a land full of scary places that turned us into a nation of scary people. But this was the final tragedy of suburbia: we put up thousands of places that aren't worth caring about, not understanding that when we had enough of them, we might be left with a nation not worth defending.

So there you have a comprehensive "to do" list of efforts we can make to meet the challenges of the permanent global energy crisis, things we can do to mount an intelligent response to these circumstances that reality is sending our way. Growing more of our food locally; restoring our railroads and other forms of public transit; rebuilding local networks of commerce and economic interdependency; reorganizing education at an appropriate scale for the future.

We cannot assume a seamless transition between where we are today and where we're going. It maybe turbulent and disorderly.

We cannot assume that technology alone will rescue us. In fact, one of the major obstacles to clear thinking these days is the mistaken belief that technology and energy are the same thing; that they are interchangeable; that if you run out of one, you can just plug in the other.

Energy and technology are related to each other but they are not the same. Technology may help us get energy resources, or use energy resources, but it is not an energy resource itself. We assume magical properties for technology largely because, in our lifetimes, the energy has always been there behind it, steady, dependable, and cheap.

What's more energy and technology both entail very insidious side effects. Energy throws off entropy, a protean force of disorder and loss that manifests in everything from the wasted heat coming out of an engine tailpipe to the immersive ugliness of the American commercial highway strip -- which is entropy-made-visible.

Technology throws off diminishing returns, in the sense that the more complex you make things, often the worse the effect on society as a whole. My favorite example is the telephone system. For more than two decades we have invested billions in computerizing every phone system in the land. The net result, after all that investment and effort, is that it is practically impossible to reach a live human being on a telephone -- not to mention the monumental ten-times-a-day aggravation of getting booted into a computerized phone menu leading to the purgatory of terminal "hold."

I hope we can overcome our tendencies to try to get something for nothing and to engage in wishful thinking. The subject of hope itself is an interesting one. College kids on the lecture circuit always ask me if I can give them some hope. Apparently, they find this view of the future to be discouraging. It may mean fewer hours playing Grand Theft Auto with a side order of Domino's pepperoni pizza, but there are many positive implications for our lives in the future. We may once again live in places worth caring about, where beauty and grace are considered everybody's birthright. We may work side-by-side with our neighbors, on things that are meaningful. Instead of canned entertainments, we may hear the sounds of our own voices making music, see the works of our own dramatists and dancers.

Hope is something we really have to supply for ourselves. We are our own generators of hope, and we do it by demonstrating to ourselves that we are capable of facing the circumstances of our time, of working competently to meet these challenges, and of learning the difference between wishing and doing. In fact, what we need is not so much hope, but confidence in our inherent abilities and the will to act.

We've got a lot to do. We've got to put down the iPods and get busy. There's no time for hand-wringing and whining. As Yogi Berra said, our whole future's ahead of us.

The Truth About Hydrogen

Source: Popular Mechanics

BY Jeff Wise
Published in the November, 2006 issue

hydrogen1106_450w.jpg

WHEN ASSESSING THE State of the Union in 2003, President Bush declared it was time to take a crucial step toward protecting our environment. He announced a $1.2 billion initiative to begin developing a national hydrogen infrastructure: a coast-to-coast network of facilities that would produce and distribute the hydrogen for powering hundreds of millions of fuel cell vehicles. Backed by a national commitment, he said, "our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom, so that the first car driven by a child born today could be powered by hydrogen, and pollution-free." With two years to go on the first, $720 million phase of the plan, PM asks that perennial question of every automotive journey: Are we almost there?

And the inevitable answer from the front seat: No. Promises of a thriving hydrogen economy — one that supports not only cars and trucks, but cellphones, computers, homes and whole neighborhoods — date back long before this presidency, and the road to fulfilling them stretches far beyond its horizon.

The Department of Energy projects the nation's consumption of fossil fuels will continue to rise — increasing 34 percent by 2030. When burned, these carbon-based fuels release millions of tons of carbon dioxide into the atmosphere, where the gas traps heat and is believed to contribute to global warming.

At first glance, hydrogen would seem an ideal substitute for these problematic fuels. Pound for pound, hydrogen contains almost three times as much energy as natural gas, and when consumed its only emission is pure, plain water. But unlike oil and gas, hydrogen is not a fuel. It is a way of storing or transporting energy. You have to make it before you can use it — generally by extracting hydrogen from fossil fuels, or by using electricity to split it from water.

And while oil and gas are easy to transport in pipelines and fuel tanks — they pack a lot of energy into a dense, stable form — hydrogen presents a host of technical and economic challenges. The lightest gas in the universe isn't easy to corral. Skeptics say that hydrogen promises to be a needlessly expensive solution for applications for which simpler, cheaper and cleaner alternatives already exist. "You have to step back and ask, 'What is the point?'" says Joseph Romm, executive director of the Center for Energy & Climate Solutions.

Though advocates promote hydrogen as a panacea for energy needs ranging from consumer electronics to home power, its real impact will likely occur on the nation's highways. After all, transportation represents two-thirds of U.S. oil consumption. "We're working on biofuels, ethanol, biodiesel and other technologies," says David Garmin, assistant secretary of energy, "but it's only hydrogen, ultimately, over the long term, that can delink light-duty transportation from petroleum entirely."

The Big Three U.S. automakers, as well as Toyota, Honda, BMW and Nissan, have all been preparing for that day. Fuel cell vehicles can now travel 300 miles on 17.6 pounds of hydrogen and achieve speeds of up to 132 mph. But without critical infrastructure, there will be no hydrogen economy. And the practical employment of hydrogen power involves major hurdles at every step — production, storage, distribution and use. Here's how those challenges stack up.

HURDLE 1: Production
The United States already uses some 10 million tons of hydrogen each year for industrial purposes, such as making fertilizer and refining petroleum. If hydrogen-powered vehicles are to become the norm, we'll need at least 10 times more. The challenge will be to produce it in an efficient and environmentally friendly way.

FOSSIL FUELS: At present, 95 percent of America's hydrogen is produced from natural gas. Through a process called steam methane reformation, high temperature and pressure break the hydrocarbon into hydrogen and carbon oxides — including carbon dioxide, which is released into the atmosphere as a greenhouse gas. Over the next 10 or 20 years, fossil fuels most likely will continue to be the main feedstock for the hydrogen economy. And there's the rub: Using dirty energy to make clean energy doesn't solve the pollution problem-it just moves it around. "As a CO2 reducer, hydrogen stinks," Romm says.

Capturing that carbon dioxide and trapping it underground would make the process more environmentally friendly. In July, General Electric and BP Amoco PLC announced plans to develop as many as 15 power plants over the next 10 years that will strip hydrogen from natural gas to generate electricity; the waste carbon dioxide will be pumped into depleted oil and gas fields. And the Department of Energy is largely funding a 10-year, $950 million project to build a coal-fed plant that will produce hydrogen to make electricity, and likewise lock away carbon dioxide to achieve what it bills as "the world's first zero-emissions fossil fuel plant."

Whether carbon dioxide will remain underground in large-scale operations remains to be seen. In addition, natural gas is a limited resource; the cost of hydrogen would be subject to its price fluctuations.

ELECTROLYSIS: Most of the remainder of today's hydrogen is made by electrically splitting water into its constituent parts, hydrogen and oxygen. This year, a PM Breakthrough Award went to GE's Richard Bourgeois for designing an electrolyzer that could drastically reduce the cost of that process. But because fossil fuels generate more than 70 percent of the nation's electrical power, hydrogen produced from the grid would still be a significant source of greenhouse gas. If solar, wind or other renewable resources generate the electricity, hydrogen could be produced without any carbon emissions at all.

NUCLEAR POWER: Next-generation nuclear power plants will reach temperatures high enough to produce hydrogen as well as electricity, either by adding steam and heat to the electrolysis process, or by adding heat to a series of chemical reactions that split the hydrogen from water. Though promising in the lab, this technology won't be proved until the first Generation IV plants come on line — around 2020.

HURDLE 2: Storage
At room temperature and pressure, hydrogen's density is so low that it contains less than one-three-hundredth the energy in an equivalent volume of gasoline. In order to fit into a reasonably sized storage tank, hydrogen has to be somehow squeezed into a denser form.

LIQUEFACTION: Chilled to near absolute zero, hydrogen gas turns into a liquid containing one-quarter the energy in an equivalent volume of gasoline. The technology is well-proven: For decades, NASA has used liquid hydrogen to power vehicles such as the space shuttle. The cooling process requires a lot of energy, though-roughly a third of the amount held in the hydrogen. Storage tanks are bulky, heavy and expensive.

COMPRESSION: Some hydrogen-powered vehicles use tanks of room-temperature hydrogen compressed to an astounding 10,000 psi. The Sequel, which GM unveiled in January 2005, carries 8 kilograms of compressed hydrogen this way-enough to power the vehicle for 300 miles. Refueling with compressed hydrogen is relatively fast and simple. But even compressed, hydrogen requires large- volume tanks. They take up four to five times as much space as a gas tank with an equivalent mileage range. Then again, fuel cell cars can accommodate bigger tanks because they contain fewer mechanical parts.

SOLID-STATE: Certain compounds can trap hydrogen molecules at room temperature and pressure, then release them upon demand. So far, the most promising research has been conducted with a class of materials called metal hydrides. These materials are stable, but heavy: A 700-pound tank might hold a few hours' fuel. However, exotic compounds now being studied could provide a breakthrough to make hydrogen storage truly practical. "High-pressure tanks are a stopgap until we can develop materials that will allow us to do solid-state storage efficiently," says Dan O'Connell, a director of GM's hydrogen vehicle program.

HURDLE 3: Distribution
Even in portable form, hydrogen is a tough substance to move from place to place. It can embrittle steel and other metals, weakening them to the point of fracture.

hydrogenstation_1106_200w.jpgCLEAN FUEL: This fueling station in Burlington, Vt., uses electricity to convert water into hydrogen for powering fuel cell cars. It is part of a Department of Energy program for testing alternative fuels in colder climates.

TRUCKING AND RAIL: Currently, most hydrogen is transported either in liquid form by tankers or as compressed gas in cylinders by trailers. Both methods are inefficient. Trucking compressed hydrogen 150 miles, for instance, burns diesel equivalent to 11 percent of the energy the hydrogen stores. It also requires a lot of round trips: A 44-ton vehicle that can carry enough gasoline to refuel 800 cars could only carry enough hydrogen to fuel 80 vehicles.

PIPELINES: One way to avoid this endless back-and-forth would be to send the hydrogen through a pipeline. About 700 miles of hydrogen pipelines now operate in the States, generally near large users such as oil refineries. The longest in the world is a 250-mile line between Belgium and France. Treating pipelines to protect them from embrittlement and high pressure makes them expensive up front-about $1 million per mile. But once built, they are the cheapest way to deliver high volumes of hydrogen.

LOCAL PRODUCTION: Given the difficulty of transporting hydrogen, why not just make it where you need it? That's what's done at roughly half the 36 hydrogen fueling stations currently operating in the U.S. Four rely on natural gas; the rest use electrolysis. In 2003, Honda introduced a Home Energy Station that performs steam reformation right in the owner's garage-but because natural gas is the feedstock, it still releases carbon dioxide to the atmosphere.

A greenhouse gas-free approach would use on-site wind or solar power to produce hydrogen through electrolysis. Honda also designed a solar-powered hydrogen refueling station, which has been operating at the company's California lab since 2001. If the national power supply becomes more eco-friendly, clean electrolysis could run off the grid.

ON-BOARD PRODUCTION: Several prototype vehicles make their own hydrogen from stored hydrocarbons, eliminating the question of distribution altogether. The DaimlerChrysler NECAR 3, for example, produces hydrogen from methanol. Researchers are also experimenting with more futuristic on-board production technologies, which combine ordinary water with reagents like boron or aluminum to produce hydrogen, oxygen and a metal oxide residue. These, however, are still a long way off.

HURDLE 4: Use
Once hydrogen reaches consumers, is there anything they can do with it except drive vehicles? Home energy generation is one other option. The question is whether hydrogen would be more practical than current methods. Hydrogen produced by steam reformation or by electrolysis loses energy when it is converted into electricity. The resulting efficiency is roughly equal to that of today's power plants — which pay a lot less for raw materials. Direct generation of electricity through wind and solar power will also be more efficient for most stationary applications. That leaves transportation as the most promising use for hydrogen.

INTERNAL COMBUSTION: The most straight-forward approach is to burn hydrogen in an adapted model of your garden-variety internal-combustion engine (ICE). Since little modification is required, these engines are relatively cheap, and 25 percent more efficient than gasoline-powered engines. BMW built its first hydrogen ICE back in the 1970s, and the concept still has legs: Ford began production of a hydrogen ICE shuttle bus last July.

hydrogenfuelcell1106_200.jpgFUEL CELL: First invented in 1839, a fuel cell combines hydrogen and oxygen to generate electricity without any moving parts. Several different varieties exist, but only the proton exchange membrane (PEM) fuel cell is lightweight and responsive enough to be practical for vehicle use. Though twice as efficient as ICEs, PEM fuel cells are hindered by high prices — even in mass production, they would currently cost about $36,000 each.

Once the technical hurdles are crossed, hydrogen's huge price tag may still make the technology prohibitive. A recent analysis by the Department of Energy projected that a supply network adequate for even 40 percent of the light-duty fleet could cost more than $500 billion. And that leads to a classic chicken-and-egg problem: How do you get millions of Americans to buy hydrogen-powered vehicles before there's an infrastructure in place to refuel them? And how do you get energy companies to build that infrastructure before there's a potential customer base?

"Companies are not willing to invest if they don't think there's going to be a market," says Daniel Sperling, director of the Institute of Transportation Studies at UC Davis. "The government has to be behind it. There has to be leadership."

There's reason to hope the technology will advance even without much government involvement. Hydrogen fuel cells already replace batteries in niche equipment, such as TV cameras and forklifts, and provide power at remote locations, such as at cellphone towers. They even power the police station in New York's Central Park. As these applications continue to develop, they will force advances in technology that will make hydrogen vehicles more feasible. Even then, hydrogen might make the most sense for fleet vehicles that don't require widespread infrastructure for service and refueling.

Ultimately, hydrogen may be just one part of a whole suite of energy alternatives. Any one of them will involve investing heavily in new infrastructure. Though the price tag will be steep, we can't afford oil's environmental, economic and political drawbacks any longer.

HYDROGEN IS THE universe's simplest atom: a single electron orbiting a single proton. In a fuel cell, incoming hydrogen gas is separated by a catalyst at the anode into protons and electrons. The protons pass directly through a proton exchange membrane (PEM), while electrons are forced through an external circuit, causing electric current to flow. When the protons and electrons meet at the cathode, they join with oxygen to form water and heat, which are released as exhaust.

A single fuel cell produces just over 1 volt, so hundreds are stacked together for typical applications. PEM fuel cells, used in NASA's Gemini flights in the 1960s, are the design of choice for fuel cell cars, but other configurations are suited for applications ranging from laptops to power plants.

Electrolysis is the exact opposite process. Electricity from a power supply splits incoming water into protons, electrons and oxygen, which is released as a gas. Electrons reunite with protons at the cathode to produce hydrogen gas.

Other electrolysis designs being developed use solid-oxide membranes instead of PEMs, which improve efficiency but require operating temperatures of 900 to 1500 F — heat that could be supplied by nuclear reactors.

The Hydrogen Economy?

Excerpt:

In most instances, the total energy cost of producing, compressing, liquefying, transporting and deliverying [hydrogen] to the user will be far higher than the energy recovered from it. In addition, it is inconvenient and often dangerous to use. It makes no contribution whatever to energy independence — i.e., to weaning the US off Imported energy supplies — and almost no real contribution to eliminating or minimizing environmental issues such as global warming — that all has to be dealt with at the hydrogen or energy manufacturing plant and is independent of the choice of fuel.

Biodiesel and Ethanol - False Panacea

Source - NewScientist magazine, July 15-21, 2006

It appears that neither biodiesel nor ethanol are truly viable alternatives to the hydrocarbon molecule and it's unfortunate that the current 'hype' in both are leading to a false panacea in the minds of American citizens.

In the battle of the biofuels, biodiesel turns out to be greener than ethanol. Sadly, neither will go very far to replace petrol and deisel in our vehicles, however.

David Tilman at the University of Minnesota in St. Paul and his colleagues have worked out the environmental costs of producing ethanol from maize and biodiesel from soybeans. Their caluculations include the fuel needed to make and run farm machinery, and make pesticides and fertilizers.

Tilman and colleagues found that using ethanol would only reduce greenhouse gas emissions by 12 per cent compared with petrol, while biodiesel reduces emissions by 41 per cent against diesel (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.06046000103).

They caluculate that even if the US turned all its corn and soybeans into biofuel, this would cover less than 5 per cent of current needs.
