^ If Hubbert's prediction for U.S. oil peak was correct to within a few months, not even knowing about Alaska's oil deposits, then it would only be rational to take seriously the claims of geologists using the same methodology, about the immanence of world oil peak.
Peak oil is a perfect demonstration of what's wrong with mainstream economic thinking which assumes that if prices go up, more oil will be pumped. It totally ignores the reality that oil is a non-renewable resource, just as it ignores "externalities" like pollution which affect everyone. This flawed thinking is revealed by the way oil is referred with terms like: Production and Supply. This language gives the illusion that oil companies "manufacture" oil. Part of the reason why this deceptive language is used is that, while a country still has oil, it wants to insure that people continue to buy it until it is all gone. If OPEC and other producers emphasized their so-called production as "extraction" expressed as a fraction of known "reserves", people would consume less oil and start developing alternatives, because the timeframe until depletion would be apparent. So it is in the interests of the producers and distributors to keep people in the dark.
If you take a look at the chart
here, you'll see that in 1930, world oil consumption was less than 3 gigabarrels per year (or about 8 million barrels per day). Right now, in 2005, the world consumes about 83 million barrels of oil per day which works out to about 30 gigabarrels per year. This means world oil consumption has increased tenfold in only 7 1/2 decades. The rate of increase was clearly slowing down by the 70's, magnified by the oil shocks. With the Alaskan North Slope, North Sea Oil and a few other sources coming online in the 1980's, the world continued to enjoy low oil prices even as consumption increased through the rest of the 20th century. But the graph also shows that the rate of increase in extraction from more recent oil bonanzas is leveling off. Once the peak is passed, oil prices, and in fact the cost of living in general will go higher and higher.
Regarding America's well being, only a dramatic rescaling of our lives to use less energy, and an all-out Apollonian effort to develop renewable alternatives over the next couple of decades will prevent the onset of a depression far greater than that of the 1930's. At least that's what I make of it all.
