Peak Oil

Early Warning:

Following up on yesterday's post of global oil production per capita, the above graph shows oil consumption per capita for an illustrative selection of countries around the world (along with the world line in black for comparison).  You can see that the developed countries all had peak consumption in the 1970s, fell in the early 1980s, then were flat for a while and began declining again.  In Europe, that second decline began in the mid 90s and has been gradual.  In the US it started in 2005 and has been rather abrupt.

...To see the developing countries more clearly here's the same data with the y-axis blown up:

India, China, and Brazil have all been growing their per-capita consumption rapidly in recent years, unlike the West.  China and India still have considerable distance to go before reaching the world average, however.

Broadly speaking then, the developed countries have been cutting per-capita oil consumption and will be doing so further, in order to make room for consumption in the more rapidly growing economies of the developing world.  There are two ways for these cuts in consumption to happen: use oil more efficiently in the economy, or have less economy.  Since 2005, in the US, we are mainly taking the second approach.

 Although it is true that global production did not fall between 2005 and 2010, it is also accurate to observe that it did not grow very much, rising only 2.2 million barrels/day (which represents 2.6% of 2005 levels) over these 5 years. Over these same 5 years, China increased its consumption by 2.5 mb/d. Thus, although the world did produce more, everybody in the world outside of China had to make do with less.

Total global oil production, in millions of barrels per day, annual 2002-2010 (data source: EIA).

...Suppose I was trying to convince you that you are a mortal being, and your counterargument was, "but that's what you said in 2005, and I didn't die then! You said it again in 2007 and 2009, and each time you were wrong. Why should I believe you this time?"
Perhaps acknowledging one's own mortality is a similar proposition to embracing the possibility that global oil production need not continue to rise forever.
In any case, I was not among those who claimed that the peak would arrive by Thanksgiving 2005, nor 2007, nor 2011. But I am among those who did claim, and still believe, that the slow rate of increase in annual oil production over the last 5 years has caused significant economic problems for countries like the United States.
Moreover, if having been wrong in the past were a valid reason to disregard everything someone says, it might be wise to ponder these words that Daniel Yergin wrote in 2005:

There will be a large, unprecedented buildup of oil supply in the next few years. Between 2004 and 2010, capacity to produce oil (not actual production) could grow by 16 million barrels a day -- from 85 million barrels per day to 101 million barrels a day -- a 20 percent increase. Such growth over the next few years would relieve the current pressure on supply and demand.

Dissecting what went wrong with that prediction is a topic for another occasion. I believe it was based on a careful, thoughtful analysis, and provides an interesting case study in some of the challenges facing anybody who tries to make these kinds of predictions. But I do feel that the meme of "don't listen to the peak oil nuts, because they've always been wrong before" should have gotten a bit tiresome at this point. ...I submit that meeting the growing global demand for crude oil over the last five years has posed significant challenges for the world economy. And those who worry that the next 5-10 years might be like the last should not be dismissed as crackpots.
