Composition of U.S. Energy Use From renewable fuels to non-renewable fuels in 200 years Cutler J. Cleveland, Prof. Geography and Environment, Boston University ASPO-USA Boston, MA October 27, 2006
What’s so great about oil? • Incredibly energy dense • One gallon of oil produces energy equivalent to 45 people toiling all day. • Stable at room temperature • Easily stored and transported • Low cost of extraction (initially) • Versatile • Abundant http://transitionculture.org/
How do we use oil? Mainly in transportation and space heating (65%) • World uses 84 million barrels/day • U.S. uses 21 million barrels/day (25%) Peaking of World Oil Production: Impacts, Mitigation, & Risk Management Robert L. Hirsch, SAIC; Roger Bezdek, MISI; Robert Wendling, MISI February 2005

Dr. M. King HubbertUSGS Research GeophysicistShell Oil Geologist • In 1956, Hubbert predicted that US-48 oil production would peak in 1970. • Hubbert further predicted a worldwide peak at "about half a century" from 1956.
Hubbert’s Production Curve Production curve for a region = sum of the production of individual wells in the region.
In most oil regions, production lags discovery by about 40 years
Worldwide discovery peaked in 1964 Past discovery by ExxonMobil Past after Exxon-Mobil 3yr moving average
Another way to look at global peak oil • The linearization of Hubbert’s curve. • P/Q vs. Q • P=Annual production • Q=Cumulative production • World reserves are predicted to be 2.1 trillion bbl, by following the line to P=0. • We have used half. Kenneth Deffeyes, Beyond Oil (2005) p 43, world oil production
US oil productionHubbert linearization Kenneth Deffeyes, Beyond Oil (2005) p 38, US oil production
What does Hubbert’s theory mean? • The oil production rate depends linearly on the fraction of the total oil that remains to be produced. • The same is true for any other finite resource. The ease of catching fish depends mostly on how many fish remain in the pond. Kenneth Deffeyes
So what is ‘Peak Oil’? • It is the point when further expansion of oil production becomes impossible because: • New production flows are fully offset by production declines (depletion) • You never run out of oil • You do run out of incremental flows • The world depends on oil products to support growth Chris Skrebowski, Editor Petroleum Review, ASPO 2005 Conference Denver
There is much uncertainty about the size of global oil reserves and depletion rates. Roger H. Bezdek, ASPO-USA Boston 2006

Where is it? Regular Oil http://transitionculture.org/
Is it really there? Middle East reserves “jumped” in the 1980’s, after OPEC established production quotas based on reserves. • Middle East reserves may be overstated by 300 billion barrels (Salameh 2004) • Only 20% of increased reserves are genuine (Deffeyes 2005) Source: BP Statistical Review of World Energy
We import 66% of our oil What are the top 4 countries from which the US imports oil? http://www.eia.doe.gov/neic/rankings/crudebycountry.htm
US Four Main Suppliers61% of imports, 40% of total • Canada peaked in 1973 • Will rely increasingly on Alberta oil sands, which require natural gas to produce (natural gas peaked in 2001). • Mexico peaked in 2004 • Cantarell, its largest oilfield, went into irreversible decline in 2006. Mexican imported oil to US dropped 16% in 2006. • Saudi Arabia may be at peak now • When its largest field (Ghawar) peaks, KSA will peak (Matt Simmons, Simmons International, oil investment banker) • Venezuela • Producing more heavy crude each year (expensive to refine) • Nationalizing its energy industries

New York Times editorial March 1, 2006 “The concept of peak oil has not been widely written about. But people are talking about it now. It deserves a careful look—largely because it is almost certainly correct.”
Why does Peak Oil matter? • 80-95% of all transport on the planet is fueled by oil products and transport accounts for 70% of oil use • All petrochemicals are produced from oil • 99% of all lubrication is done with oil products • 95% of all goods in our stores get there using oil • 99% of our food involves oil or gas for fertilizers, agrochemicals, tilling, cultivation and transport. Chris Skrebowski, Editor Petroleum Review, ASPO 2005 Conference Denver
Challenges to the food system • Declining supply of fossil fuels • Fewer farmers • Only 1/7 of the human labor is required today as compared to 1900 (because of fossil fuels), therefore fewer people know how to farm. • Water • Snowpack in the Sierras is declining, reducing CA irrigation water. • Non-renewable aquifers are being depleted. • Will bring pressure on other regions to compensate. • Climate instability • Droughts, floods and stronger storms due to climate change • Land and topsoil availability • Soil depletion and development pressures • Decreasing genetic diversity of crops • Limits natural adaptability to the above stresses • These problems are all related to one another. The common factor is availability of cheap energy.
Substitutes for conventional oil? All are important. Together they will not deliver the flows required by current & future demand at reasonable price. We must reduce demand through efficiency and using less. • Oil sands • Oil shale • Coal & CTL • Natural gas • Wind • Solar PV & thermal • Nuclear • Hydro • Biomass • Landfills
Peaking of World Oil Production: Impacts, Mitigation, & Risk ManagementRobert L. Hirsch, SAIC, Project Leader(commissioned by US Department of Energy, February 2005) EXECUTIVE SUMMARY The peaking of world oil production presents the U.S. and the world with an unprecedented risk management problem. 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. http://www.netl.doe.gov/publications/others/pdf/Oil_Peaking_NETL.pdf
No single fuel can replace oil “Oil has the greatest energy density of any fuel known to man, apart from nuclear. This means all alternatives are inferior.” Chris Skrebowski, Editor Petroleum Review “Peak oil is a turning point in history of unparalleled magnitude, for never before has a resource as critical as oil become headed into decline from natural depletion without sight of a better substitute.” Dr. Colin Campbell, renowned oil geologist
How should we face this? • Collectively, Humanity is: • Very clever, very ingenious, very adaptable • So it is reasonable to be optimistic. • It is reasonable to anticipate technical solutions we cannot currently envisage. • But humanity is also greedy, competitive, short-sighted and tribal. • Concern & apprehension are appropriate. Chris Skrebowski, Editor Petroleum Review, ASPO 2005 Conference Denver
A Look at Climate ChangeWhy reducing fossil fuel use is essential now
Intergovernmental Panel on Climate Change Average temperatures from a range of IPCC energy scenarios short of deep cuts in fossil fuel use Threshold of severe danger: 2oC above pre-industrial average temperature (EU target not to exceed) Departures oC from the 1961 – 1990 avge.

Natural Gas Resources • U.S natural gas peaked in 2001. • Drilling has doubled in 5 years. • Production is declining. J. David Hughes, Geological Survey of Canada, ASPO-USA Boston 2006
