Kevin Drum: Chart of the Day

As I’ve mentioned before, one of the big problems with reaching peak oil isn’t just that oil prices will go up, but that they’re likely to spike up and down fairly violently. In 2006, for example, demand for oil pretty much bumped up against the total available supply, which meant that even a small amount of additional demand was enough to send oil prices spiraling up past $150 in little more than a year. The ensuing recession reduced demand by only a modest amount, but that was enough to cause oil prices to plummet to under $50 in the same timespan. And this isn’t just a demand-side problem: a small glitch in supply could easily have caused the same kinds of violent price spikes.

As a general rule, the world can handle high oil prices. In fact, to the extent that high prices get us off our butts and looking for cleaner, more sustainable sources of energy, high oil prices are a good thing. But what the world economy can’t handle is constant, huge gyrations in oil prices: nearly all of our recessions since 1973 have been jump started by a sudden spike in oil prices.
