Canada's Tar Sands

How Canada Went from 21st to 2nd in World's Oil Reserves

By Dan Woynillowicz
World Watch. Posted September 17, 2007.

The United States has its hopes pinned on Canada's "tar sands" for North American security in the oil market. But their "black gold" is an environmental nightmare.

It's well-known that the United States consumes more oil per capita than any other country in the world, absorbing two-thirds of global oil production. This heavy dependence has often, and aptly, been described as an addiction; even U.S. President George W. Bush trotted out the metaphor in his 2006 State of the Union address ("America is addicted to oil").

Most of us regard addictions (to anything) as inherently unhealthy and admission of the problem as the first step toward getting clean. In this case, however, U.S. policy has simply been to seek increased oil imports from more reliable sources closer to home, in effect, to replace distant and unstable dealers with one from the neighborhood -- specifically, Canada, already the kingpin dealer of oil to the United States. In 2005 Canada exported almost 1.5 million barrels per day to the United States, about 7 percent of U.S. daily consumption. Canada exports 66 percent of its domestic crude oil production, and since 1995 the United States has received 99 percent of these exports. At first glance, it would seem that Canada wouldn't be able to boost oil production to fill the gap; production of conventional light and heavy oil in Canada was predicted to peak in 2006 and then rapidly decline. But that's where Canada's "unconventional" tar sands come in.

Production

The vast bulk of Canada's tar sands is found in the province of Alberta, the country's most prolific producer of fossil fuels. The tar sands deposits underlie more than 140,000 square kilometers of relatively pristine boreal forest, an area larger than the state of Florida. It's estimated that the tar sands hold approximately 1.7 trillion barrels of crude bitumen (the technical term for the fossil fuel extracted from the tar sands). But most of this bitumen will never be recovered and only a fraction, 174 billion barrels, is estimated to be recoverable with today's technology and under current and anticipated economic conditions.

When the U.S. Department of Energy formally acknowledged these reserves in 2003, it vaulted Canada's oil reserves from 21st to 2nd in the world, behind only Saudi Arabia. It's little wonder then that the U.S. Energy Policy Development Group has described the tar sands as "a pillar of sustained North American energy and economic security." Canada's so-called "black gold" has come to be regarded as an abundant, secure, and affordable source of crude oil. But development of this unconventional fossil fuel comes with unconventional risks and consequences. Everything about the tar sands is big, most significantly its global warming and environmental implications -- leading some to now describe the tar sands as "Canada's dirty secret."

Producing oil from the tar sands is scraping the bottom of the oil barrel. Tar sands consist of a mixture of 85 percent sand, clay, and silt; 5 percent water; and 10 percent crude bitumen, the tarlike substance that can be converted to oil. Bitumen doesn't flow like crude oil, and getting it out of the tar sands is a messy job. The current technology, which has evolved relatively little since it was first developed in the early 20th century, is a hot water-based separation process that requires huge quantities of water and energy (see diagram). Imagine mixing a bucket of roofing tar into a child's sandbox. Then boil some water, pour it into the sandbox, and try to wash the tar out of the sand.

Most tar sands production takes place in vast open-pit mines, some as large as 150 square kilometers and as deep as 90 meters. Before strip-mining can begin, the boreal forest must be clear-cut, rivers and streams diverted, and wetlands drained. The overburden (the soil, rocks, and clay overlying the tar sands deposit) must be stripped away and stockpiled to reach the bitumen. Four tons of material are moved to produce every barrel of bitumen.

At current production rates, with just three mines operating, enough material is moved every two days to fill a 60,000-seat stadium. But only a small fraction of the bitumen deposits is close enough to the surface to be strip-mined. Over 80 percent of the established tar sands reserves are deeper and must be extracted in situ (in place) by injecting high-pressure steam into the ground to soften the bitumen so it can be pumped to the surface.

Once separated from the sand, the bitumen is still a low-grade, heavy fossil fuel that must undergo an energy-intensive process to upgrade it into a synthetic crude oil more like conventional crude, either by adding hydrogen or removing carbon. Upgrading the bitumen usually occurs before it is shipped to refineries, but sometimes raw bitumen is diluted (e.g., with naphtha) and pipelined to a refinery where it is both upgraded and refined. In the United States about three-quarters of the oil is refined into transportation fuels.

But even then not just any refinery will do. A certain amount of reconfiguring must occur at refineries more accustomed to handling conventional crude oil. Some American refineries, primarily in the Midwest and the Rocky Mountain region, already accept some synthetic crude oil from the tar sands. But with growing reliance on this source of oil, numerous American refineries are converting or expanding in order to handle tar sands-derived synthetic crude oil or raw bitumen.

Impacts

The environmental consequences of oil production from tar sands are major, beginning with its effect on climate change. North America's transition to oil from the tar sands not only perpetuates, but actually worsens, emissions of greenhouse gas pollution from oil consumption.

While the end products from conventional oil and tar sands are the same (mostly transportation fuels), producing a barrel of synthetic crude oil from the tar sands releases up to three times more greenhouse gas pollution than conventional oil. This is a result of the huge amount of energy (primarily from burning natural gas) required to generate the heat needed to extract bitumen from the tar sands and upgrade it into synthetic crude. The energy equivalent of one barrel of oil is required to produce just three barrels of oil from the tar sands.

In 2002 the Canadian government ratified the Kyoto Protocol on global warming, legally committing to a target of reducing the country's greenhouse gas pollution by 6 percent below 1990 levels by 2012. But the rapid growth of tar sands development and oil industry lobbying have undermined efforts to reduce greenhouse gas pollution for over a decade.

Since 1990, Canada's total emissions have risen 25.3 percent, a pace far exceeding the 16.3 percent increase in the United States, the second-fastest-rising nation, according to United Nations data. Regulations introduced in early 2007 are so fraught with loopholes and gaps that greenhouse gas pollution from tar sands is predicted to triple by 2020. Canada's greenhouse gas emissions in 2020 are projected to be 2 percent above 1990 levels. The environmental consequences of tar sands development hardly stop with climate change. Nowhere in the world is there a form of oil extraction and processing with more intense impacts on forests and wildlife, freshwater resources and air quality.

Forests. The tar sands are found beneath boreal forest, a complex ecosystem that comprises a unique mosaic of forest, wetlands and lakes. Canada's boreal forest is globally significant, representing one-quarter of the world's remaining intact forests. Beyond the ecosystem services it provides (cleansing water, producing oxygen and storing carbon), it is home to a wide variety of wildlife, including bears, wolves, lynx and some of the largest populations of woodland caribou left in the world. Its wetlands and lakes provide critical habitat for 30 percent of North America's songbirds and 40 percent of its waterfowl.

If currently planned tar sands development projects unfold as expected, approximately 3,000 square kilometers of boreal forest could be cleared, drained and strip-mined to access tar sands deposits close to the surface, while the remaining 137,000 square kilometers could be fragmented into a spider's web of seismic lines, roads, pipelines and well pads from in situ drilling projects. Studies suggest that this scale of industrial development could push the boreal ecosystem over its ecological tipping point, leading to irreversible ecological damage and loss of biodiversity.

Satellite images readily illustrate the magnitude of boreal forest impacts from tar sands mining operations. The United Nations Environment Program has identified Alberta's tar sands mines as one of 100 key global "hotspots" of environmental degradation. According to Environment Canada (the Canadian equivalent to the U.S. Environmental Protection Agency), development of the tar sands presents "staggering challenges for forest conservation and reclamation."

Very little of the area directly affected by mining operations has been reclaimed, and after 40 years of mining, not a single operation has received a reclamation certificate from the government of Alberta. Suncor Energy's operation, the longest-operating tar sands mine, says it has reclaimed 858 hectares of land since starting operations in 1967, less than 9 percent of the land its operations have disturbed to date. Syncrude Canada, the largest daily producer of tar sands, says its operations have disturbed 18,653 hectares since 1978, with just 4,055 hectares of land reclaimed. None of this reclaimed land has been certified as such. At best, reclamation of the tar sands region will be a large-scale experiment that is unlikely to restore a self-sustaining boreal forest ecosystem within the next century.

Waters. The Athabasca River winds nearly 1,500 kilometers from its source at the Athabasca Glacier in Jasper National Park to Lake Athabasca in Wood Buffalo National Park. It is Alberta's longest river and one of North America's longest undammed rivers. It enters Lake Athabasca at the Peace-Athabasca Delta, the largest boreal delta in the world, a World Heritage Site, and one of the most important waterfowl nesting and staging areas in North America.

It also passes directly through the boreal forest being cleared and strip-mined, and serves as the primary source of water used to separate the bitumen from the mined tar sands. Water withdrawals for tar sands surface mining operations pose threats to both the sustainability of fish populations in the Athabasca River and to the sustainability of the Peace-Athabasca Delta, jeopardizing the subsistence and commercial fisheries of local aboriginals.

Tar sands mining operations withdraw 2-4.5 barrels of fresh water from the river for every barrel of oil they produce. Current operations are permitted to withdraw more than 349 million cubic meters of water per year, a volume equivalent to the amount required by a city of 2 million people. But unlike city effluent waters, which are treated and released back into the river, tar sands mining effluent becomes so contaminated that it must be impounded.

Historically it was believed that the Athabasca River had sufficient water flows to meet the needs of tar sands operations. But it is becoming clearer that this might not be the case, particularly during the winter months, when river flows are naturally lower and growing demand for water withdrawals could lead to long-term ecological impacts. The sustainability of fish populations in the Athabasca River is threatened by continuous tar sands water withdrawals during the winter months in years when low precipitation rates in the Athabasca River basin lead to low flow conditions. Nonetheless, the government has failed to implement regulations that would require tar sands withdrawals to stop when the health of the river is at risk. In fact, the government explicitly allows the tar sands industry to continue withdrawing water no matter how low the river flows become.

For certain in situ drilling operations, significant amounts of water are required to create steam to be injected underground. Because the steam condenses into water and is pumped up with the bitumen, the water can be recycled. However, because some water remains underground, a continuous source of additional water (about half a barrel of water per barrel of bitumen) is required.

These operations are located much farther from the river and, as a result, rely mainly upon groundwater. Where shallower freshwater aquifers are used, the continuous pumping of water can lower the water table in the region. Because these groundwater aquifers are connected to lakes, rivers and wetlands, reducing their levels can cause lakes to shrink and wetlands to dry out. As a result, some operators have switched to deeper sources of salty groundwater. But because they require fresh water, the salty water must be treated, which produces large amounts of waste sludge that must be disposed of.

Both tar sands mining and in situ operations produce large volumes of waste as a result of their water use. For in situ operations, the primary waste stream, a result of treating salt water and the water that is pumped up with the bitumen, is disposed of in landfills or injected underground. Tar sands mining operations present a much more significant risk, because they produce large volumes of waste in the form of mine tailings (six barrels of tailings per barrel of bitumen extracted). These tailings, a slurry of water, sand, fine clay and residual bitumen, are stored in vast wastewater reservoirs.

The industry misleadingly refers to them as "tailings ponds," but collectively these pools of waste cover more than 50 square kilometers and are so extensive that they can be seen from space. One tailings pond at Syncrude's mining operation is held in check by the third-largest dam in the world. These tailings dumps pose an environmental threat resulting from the migration of pollutants through the groundwater system and the risk of leaks to the surrounding soil and surface water.

The high concentrations of pollutants such as naphthenic acids, which are found at concentrations 100 times greater than in the natural environment, are acutely toxic to aquatic life, yet the government has no water-quality regulations for these substances. Migratory birds fare slightly better: To prevent them from landing, propane cannon go off at random intervals and scarecrows stand guard on floating barrels. How this tailings waste, and its grave risks, might be dealt with in the long term remains unknown.

Air. Tar sands air pollution, both provincial and transboundary, is rapidly increasing. Since 2003 Alberta has been the industrial air pollution capital of Canada. Criteria Air Contaminants (CACs) are the most common air pollutants released by heavy industry burning fossil fuels. CACs are defined as "air pollutants that affect our health and contribute to air pollution problems" and include such things as nitrogen oxides (NOX), sulfur dioxide (SO2), volatile organic compounds and particulate matter, all of which are emitted in large volumes by tar sands operations.

Modeling of the impacts of approved tar sands development, which includes three operating mines and three operations at various stages of planning and construction, shows that maximum predicted ambient air concentrations of NOX and SO2 would exceed provincial, national and international guidelines. Emissions of volatile organic compounds such as benzene are also on the rise because of both emissions from burning fossil fuels (e.g., natural gas, diesel, coke) and the growing number of tailings ponds. The costs of such air pollution have not been considered.

The coming tar sands rush

Major global powers are positioning themselves to ensure access to oil from tar sands. To date, four of the five largest publicly traded oil companies in the world (Royal Dutch/Shell, ExxonMobil, ChevronTexaco, and TotalFina) have invested or committed themselves to invest billions of dollars in tar sands development. National oil companies have also staked their claim, ranging from Norway's Statoil to China's Sinopec.

Tar sands speculation, investment and development has grown dramatically. The oil industry's production target of 1 million barrels per day was achieved in 2004, 16 years ahead of the ambitious schedule for growth it laid out in 1995. That year the industry invested almost US$9 billion in Alberta's tar sands. More than US$100 billion of investment has been announced for development between 2006 and 2015.

The tar sands industry is now focused on quintupling production as quickly as possible. It is projected that tar sands production will reach 3-4 million barrels per day by 2015 and could grow to 5 million barrels per day by 2030, if not sooner. It is the prospect of this growth that has led Canadian Prime Minister Stephen Harper to label Canada an "emerging energy superpower."

The magnitude of the environmental risks and liabilities arising from Canada's tar sands rush is unprecedented in the history of North American energy production. Growing awareness about the global warming and environmental consequences of relying upon growth in tar sands production throws into sharp relief the perils of our addiction to oil in the 21st century. All North Americans, including future generations, have a stake in the outcome.

To address the impacts of tar sands production, a novel suite of government policies and innovative technologies must be deployed that drastically reduce the environmental impacts by achieving "carbon neutral" (no net greenhouse gas pollution) production, ensuring that development doesn't proceed any faster than reclamation of the boreal forest and reducing dependence on scarce freshwater resources.

The most immediate opportunity to begin our rehabilitation lies in the more efficient use of transportation fuels. To do so requires tackling another sacred cow: the flagging North American auto industry, which is in trouble partly because it is producing the wrong vehicles for the times. The abysmal fuel-efficiency of North America's SUVs, trucks and cars has actually declined since 1986.

The governments of the United States and Canada must collectively commit to implementing regulations that will make North America a global leader in fuel efficiency. By deploying more efficient technologies today, we can begin to ease the demand for transportation fuels and slow the headlong rush into extracting oil from the tar sands. This will afford policymakers and the private sector the time needed to drive investment toward low-carbon and no-carbon fuels, and to evolve our transportation systems and urban design into a state that is compatible with a carbon-free future. North America stands at a critical juncture in its transportation fuel future.

As conventional oil sources disappear, we face a stark choice: We can develop new, even dirtier sources of transportation fuels derived from fossil fuels like the tar sands, or we can set a course for a more sustainable energy future by improving the efficiency of our oil consumption while aggressively transitioning to clean and renewable transportation fuels and sustainable transportation systems.

The environmental and global warming consequences of even 1 million barrels per day of tar sands production must serve as a wake-up call, and we must acknowledge that increased reliance upon this unconventional, high-impact fossil fuel is not a viable path forward.

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 Paradigm Shift: Energy Return on Energy Invested (EROEI)

Source: Petrodollar Warfare by William R. Clark

One of the crucial concept required to understand the importance of Peak Oil relates to a phenomenon in physics commonly described as Energy Return on Energy Invested, or EROEI. Unlike the traditional financial metric, Return on Investment (ROI), EROEI refers to the amount of energy spent compared to the energy extracted. EROEI is the ratio between energy expended to extract a barrel of oil, versus the energy provided by that barrel of oil.

Fifty years ago when some of the super-giant oil fields were still being discovered, one of these could produce an EROEI of 200, that is, energy 200 times greater than the actual energy expended to extract the oil. In contrast, oil wells in deep water currently achieve an EROEI of 5. Oil removed from the tar sands, as found in Canada (and Venezuela), have a very low EROEI of 1.5, along with a slow extraction process.

Once global Peak Oil is reached and exceeded, a critical point is attained on the downward side of Hubbert's curve, when it requires more energy to extract a given unit of oil than what it will produce if extracted. Of the remaining oil in the ground or at the bottom of the ocean, a positive EROEI is required if that oil is the be used as transportation fuel. To reiterate, when the energy required to extract very low-grade or geographically undesirable oil is equal to or greater than the energy that would be provided by that new barrel of oil, it will no longer be logical to expend the energy to extract the oil. In such a scenario, the EROEI for that oil field becomes an energy sink, and the oil will simply remain in the ground.

It is for these reasons that the world will never technically run out of oil; rather, it will ultimately become simply too energy-intensive to extract low-quality or geographically inaccessible oil. Unlike ROI calculations, the amount of money invested in a mature oil field is completely irrelevant if the energy required to extract the oil is greater than the energy that would be derived from recovering the oil.

Despite the historic, social, economic, and geopolitical implications of global Peak Oil, many governments still appear reluctant to publish this information — even though the facts regarding global oil discovery and production are perfectly apparent to the rational observer. Instead, the global society has acquired an unfounded belief that more oil will be discovered as needed in order to further economic growth, but this is a false construct.

Peak Oil Primer

What is Peak Oil?

Peak Oil is the simplest label for the problem of energy resource depletion, or more specifically, the peak in global oil production. Oil is a finite, non-renewable resource, one that has powered phenomenal economic and population growth over the last century and a half. The rate of oil 'production,' meaning extraction and refining (currently about 84 million barrels/day), has grown in most years over the last century, but once we go through the halfway point of all reserves, production becomes ever more likely to decline, hence 'peak'. Peak Oil means not 'running out of oil', but 'running out of cheap oil'. For societies leveraged on ever increasing amounts of cheap oil, the consequences may be dire. Without significant successful cultural reform, economic and social decline seems inevitable.


Why does oil peak? Why doesn't it suddenly run out?

Oil companies have, naturally enough, extracted the easier-to-reach, cheap oil first. The oil pumped first was on land, near the surface, under pressure, light and 'sweet' (meaning low sulfur content) and therefore easy to refine into gasoline. The remaining oil, sometimes off shore, far from markets, in smaller fields, or of lesser quality, takes ever more money and energy to extract and refine. Under these conditions, the rate of extraction inevitably drops. Furthermore, all oil fields eventually reach a point where they become economically, and energetically, no longer viable. If it takes the energy of a barrel of oil to extract a barrel of oil, then further extraction is pointless.


M. King Hubbert - the first to predict an oil peak

Hubbert's Peak Chart
The Hubbert Curve is used to predict the rate of production from an oil producing region containing many individual wells. Source: aspoitalia.net

In the 1950s a U.S. geologist working for Shell, M. King Hubbert, noticed that oil discoveries graphed over time, tended to follow a bell shape curve. He posited that the rate of oil production would follow a similar curve, now known as the Hubbert Curve (see figure). In 1956 Hubbert predicted that production from the US lower 48 states would peak between 1965 and 1970. Shell tried to pressure Hubbert into not making his projections public, but the notoriously stubborn Hubbert went ahead and released them. In anycase, most people inside and outside the industry quickly dismissed Hubbert's predictions. In 1970 US oil producers had never produced as much, and Hubbert's predictions were a fading memory. But Hubbert was right, US continental oil production did peak in 1970, although it was not widely recognized for several years, and only with the benefit of hindsight.

No oil producing region fits the bell shaped curve exactly because production is dependent on various geological, economic and political factors, but the Hubbert Curve remains a powerful predictive tool.

Although it passed by largely unnoticed, the U.S. oil peak was arguably the most significant geopolitical event of the mid to late 20th Century, creating the conditions for the energy crises of the 1970s, leading to far greater U.S. strategic emphasis on controling foreign sources of oil, and spelling the begining of the end of the status of the U.S as the world's major creditor nation. The U.S. of course was able to import oil from elsewhere, and life continued there with only minimal interuption. When global oil production peaks however, the implications will be far greater.


So when will oil peak globally?

Hubbert went on to predict a global oil peak between 1995 and 2000. He may have been close to the mark except that the oil shocks of the 1970s slowed our use of oil. As the following figure shows, global oil discovery peaked in the late 1960s. Since the mid-1980s, oil companies have been finding less oil than we have been consuming.

Oil Production and Discovery Chart

Of the 65 largest oil producing countries in the world, up to 54 have past their peak of production and are now in decline, including the USA (in 1970/71) and the North Sea (in 2001). Hubbert's methods, and variations on them, have been used to make various projections about the global oil peak, with results ranging from 'already peaked', to the very optimistic 2035. Many of the official sources of data used to model oil peak such as OPEC figures, oil company reports, and the USGS discovery projections, upon which the international energy agencies base their own reports, can be shown to be very unreliable. Several notable scientists have attempted independent studies, most notably Colin Campbell and the Association for the Study of Peak Oil and Gas (ASPO).

ASPO: Oil & Gas Production Profiles, 2005 Base Case Chart
Source: peakoil.ie

ASPO's latest model suggests that 'regular' oil peaked in 2004. If heavy oil, deepwater, polar and natural gas liquids are considered, the oil peak is projected for around 2010. Combined oil and gas, as shown above, are expected to also peak around 2010. Other researchers such as Kenneth Deffeyes and A. M. Samsam Bakhtiari have produced models with similar or even earlier projected dates for oil peak. Precise predictions are difficult as much secrecy shrouds important oil and gas data.

Other quite different types of analysis have provided supporting evidence to these 'early peak' scenarios, most notably UK Petroleum Review editor Chris Skrebowski's Oilfields Megaproject reports, and energy banker Matthew Simmons' analysis of Saudi Arabian oil fields.

The effects of natural gas peak are more localized due to the economic and energetic expense of liquefying and transporting natural gas as LNG. Both British and North American natural gas production have already peaked, so these nations may be facing dual energy crises.


What does Peak Oil mean for our societies?

Our industrial societies and our financial systems were built on the assumption of continual growth – growth based on ever more readily available cheap fossil fuels. Oil in particular is the most convenient and multi-purposed of these fossil fuels. Oil currently accounts for about 43% of the world's total fuel consumption [PDF], and 95% of global energy used for transportation [PDF]. Oil is so important that the peak will have vast implications across the realms of geopolitics, lifestyles, agriculture and economic stability. Significantly, for every one joule of food consumed in the United States, around 10 joules of fossil fuel energy have been used to produce it.


The 'Hirsch Report'

A risk mitigation study on Peak Oil was released in early 2005, commissioned by the US Department of Energy. Prepared by the Science Applications International Corporation (SAIC), and titled “Peaking of World Oil Production: Impacts, Mitigation and Risk Management” [PDF], it is known commonly as the Hirsch Report after its primary author Robert L. Hirsch. The executive summary of the report warns that "as peaking is approached, liquid fuel prices and price volatility will increase dramatically, and, without timely mitigation, the economic, social, and political costs will be unprecedented. Viable mitigation options exist on both the supply and demand sides, but to have substantial impact, they must be initiated more than a decade in advance of peaking." [Emphasis added.] Unfortunately nothing like the kind of efforts envisaged have yet begun.


But it's just oil - there are other fossil fuels, other energy sources, right?

To evaluate other energy sources it helps to understand the concepts of Net Energy, or the Energy Returned on Energy Invested ratio (EROEI). One of the reasons our economies have grown so abundant so quickly over the last few generations is precisely because oil has had an unprecedently high EROEI ratio. In the early days of oil, for every barrel of oil used for exploration and drilling, up to 100 barrels of oil were found. More recently, as oil recovery becomes more difficult, the ratio has become significantly lower. Certain alternative energy 'sources' may actually have EROEI ratios of less than one, such most methods of industrially producing biodieseland ethanol. That is, when all factors are considered, you probably need to invest more energy into the process than you get back.

Hydrogen, touted by many as a seamless solution, is actually an energy carrier, but not an energy source. Hydrogen must be produced using an energy source such as natural gas or nuclear power. Because of energy losses in transformation, the hydrogen will always contain less energy than was invested in it.

Some alternatives such as wind and hydro-power may have much better ERoEI, however their potential expansion may be limited by various physical factors. Even in combination it may not be possible to gather from renewable sources of energy anything like the amount of energy that industrial society is accustomed to. Richard Heinberg uses the metaphor that whereas fossil fuels might be considered a massive energy inheritance, and one spent perhaps unwisely, renewables are much more akin to a hard won energy wage.

For certain tasks, such as air travel, no other energy source can readily be substituted for oil. As noted by the Hirsch Report, alternative energy infrastructures require long periods of investment, on the scale of decades, to be widely implemented. We may be already leaving the period of cheap energy before we have begun seriously embarking on this task.

It's perhaps worth noting briefly that any ERoEI study is complex and different methods of accounting can come up with vastly different results, so any net energy study might be viewed with some suspicion. Perhaps the best method yet developed is Howard Odum's eMergy analysis. But we may not know with total certainty the usefulness of any renewable energy technologies until the hidden fossil fuel energy subsidies are finally removed.


What can be done?

Many people are working on partial solutions at various different levels, but there is probably no cluster of solutions which do not involve some major changes in lifestyles, especially for the global affluent. Peak Oil presents the potential for quite catastrophic upheavals, but also some more hopeful possibilities, a chance to address many underlying societal problems, and the opportunity return to simpler, healthier and more community oriented lifestyles.

The Post Carbon Institute Outposts. The Post Carbon Institute is a think tank devoted to exploring the implications of, and preparing for, Peak Oil, focusing on relocalization. They write, “the most important initiative of the Post Carbon Institute is working with groups of concerned citizens to prepare their community for the Post Carbon Age. These groups are Outposts in the sense that they are community-based extensions of the Post Carbon Institute; they operate autonomously yet receive guidance and electronic infrastructure from the Institute. Outposts work cooperatively in their local community to put theory about living with less hydrocarbons into practice while sharing knowledge and experiences with the global network of outposts.”

The Community Solution to Peak Oil. Many excellent resources are available through the website of this US based organisation "dedicated to the development, growth and enhancement of small local communities... that are sustainable, diverse and culturally sophisticated." The Community Solution have organised two recent grassroots Peak Oil conferences, and have developed a case study of Cuba, a country which has relatively successfully adapted to an artificial oil peak.

Permaculture: Permaculture is a 'design science' which can allow us to live in relative abundance with minimal resource use. Permaculture principles can be used to functionally redesign social systems, built environments, ecological and agricultural practices for energy descent. David Holmgren's recent book, Permaculture: Principles and Pathways Beyond Sustainability, deals explicitly with the global oil peak and proposes permaculture as the best set of strategies for dealing with 'energy descent'.

Local Energy Descent Action plans: Several communities around the world have begun their own preparations for Peak Oil, and are documenting the process. The Kinsale Energy Descent Action Plan out of rural Ireland is the world's first local action plan for Peak Oil, dealing with many issues including health, education, tourism and youth issues. Local organisers within the town of Willits, Califonia have begun work on the Willits Economic LocaLization Project in response to Peak Oil.

Local Currencies and Steady State Economics:
Local Currencies: Richard Douthwaite, a 'recovering economist', has proposed a number of alternative monetary systems to deal with energy decline and the associated monetary crises which might arise post-peak. Local currencies like LETS are in operation around the planet already (although LETS itself may be somewhat problematic). Experiment now with local currencies to help survive economic crises.
The Foundation for the Economics of Sustainability (FEASTA) has some of Richard Douthwaite's publications available for free online, including entire books as well as masses of other excellent research and articles by other writers, relating not just to economics and local currencies, but to various aspects of sustainability. See also: www.communitycurrency.org/resources.html Steady State Economics: The Center for the Advancement of the Steady State Economy (CASSE) promote alternatives to the ecological insanity of growth based economics. Read their position paper here:

Intentional Communities: Intentional Community (IC) is an inclusive term for ecovillages, cohousing, residential land trusts, communes, student co-ops, urban housing cooperatives and other related projects and dreams... ICs represent one of the sanest ways of dealing with energy peak.
