The peak oil world seems to have (thankfully) mostly moved from viewing the defining aspect of the peak of oil production as a function of oil in the ground to being a function of the price it takes to produce new oil - David Strahan has a good example of this at his blog - HAS THE WORLD REACHED ECONOMIC PEAK OIL? ...oil is so useful that nobody cuts back voluntarily, meaning prices must rise to excruciating levels to force rich western consumers to economise. The first “peak oil recession” started in 2009, says Kopits. It took oil at $147 a barrel and the deepest recession since the 1930s to prise oil from the grip of consumers in OECD countries. Since early 2008, OECD oil consumption has fallen by 4 mb/d, while non-OECD consumption – mainly inChina– has gained 6 mb/d. Global oil production rose 2 mb/d during that period, so developing countries have consumed all the additional supply plus that given up by industrialised economies. “China is bidding away the OECD oil supply,” says Kopits, “and recessions are the mechanism by which that oil is being transferred from weaker economies to faster growing economies.”...Analysts at Deutsche Bank are more optimistic, and predict that a final oil price spike to $175 in 2015 will lead to rapid electrification of transport and relieve pressure on the oil supply. But Kopits is doubtful that we can escape so easily. “Buckle up,” he concludes, “we’re in for a bumpy ride.”
