Since the beginning of the 21st century, a fear has come to pervade the prospects for oil, fueling anxieties about the stability of global energy supplies. It has been stoked by rising prices and growing demand, especially as the people of China and other emerging economies have taken to the road. This specter goes by the name of "peak oil."
Its advocates argue that the world is fast approaching (or has already reached) a point of maximum oil output. They warn that "an unprecedented crisis is just over the horizon." The result, it is said, will be "chaos," to say nothing of "war, starvation, economic recession, possibly even the extinction of homo sapiens." The date of the predicted peak has moved over the years. It was once supposed to arrive by Thanksgiving 2005. Then the "unbridgeable supply demand gap" was expected "after 2007." Then it was to arrive in 2011. Now "there is a significant risk of a peak before 2020."

However, the real story is Global Net Oil Exports (GNE), which have shown a measurable multimillion barrel per day decline since 2005, and which are measured in terms of total petroleum liquids, with 21 of the top 33 net oil exporters showing lower net oil exports in 2010, versus 2005. An additional metric is Available Net Exports (ANE), which we define as GNE less Chindia's (China + India’s) combined net oil imports. ANE have fallen at an average volumetric rate of about one mbpd per year from 2005 to 2010, from about 40 mbpd in 2005 to about 35 mbpd in 2010 (BP + Minor EIA data, total petroleum liquids).
At the current rate of increase in the ratio of Chindia's net imports to GNE, Chindia would consume 100% of GNE in about 20 years. Contrary to Mr. Yergin’s sunny pronouncements, what the data show is that developed countries like the US are being forced to take a declining share of a falling volume of GNE. In fact, our work suggests that the US is well on its way to “freedom” from its reliance on foreign sources of oil, just not in the way that most people hoped.
In a November, 2004 interview in Forbes, Mr. Yergin asserted that oil prices would be back to a long term price ceiling of $38 by late 2005--because of a steady increase in global crude oil production. It turned out that Mr. Yergin’s predicted price ceiling has so far been the price floor. The lowest monthly spot crude oil price that the EIA shows for post-November, 2004 is $39.
I suspect that just as Mr. Yergin was perfectly wrong about oil prices, he may be confidently calling for decades of rising production, just as we come off the current production plateau and just as an accelerating decline in Global Net Exports kicks in.
