Has Petroleum Production Peaked, Ending the Era of Easy Oil?

A new analysis concludes that easily extracted oil peaked in 2005, suggesting that dirtier fossil fuels will be burned and energy prices will rise
Despite major oil finds off Brazil's coast, new fields in North Dakota and ongoing increases in the conversion of tar sands to oil in Canada, fresh supplies of petroleum are only just enough to offset the production decline from older fields. At best, the world is now living off an oil plateauroughly 75 million barrels of oil produced each and every daysince at least 2005, according to a new comment published in Nature on January 26. (Scientific American is part of Nature Publishing Group.) That is a year earlier than estimated by the International Energy Agencyan energy cartel for oil consuming nations.
To support our modern lifestylesfrom cars to plasticsthe world has used more than one trillion barrels of oil to date. Another trillion lie underground, waiting to be tapped. But given the locations of the remaining oil, getting the next trillion is likely to cost a lot more than the previous trillion. The "supply of cheap oil has plateaued," argues chemist David King, director of the Smith School of Enterprise and the Environment at the University of Oxford and former chief scientific adviser to the U.K. government. "The global economy is severely knocked by oil prices of $100 per barrel or more, creating economic downturn and preventing economic recovery."
Nor do King and his co-author, oceanographer James Murray of the University of Washington in Seattle, hold out much hope for future discoveries. "The geologists know where the source rocks are and where the trap structures are," Murray notes. "If there was a prospect for a new giant oil field, I think it would have been found."
