The Economist:

We believe that they are wrong, and that oil is close to a peak. This is not the “peak oil” widely discussed several years ago, when several theorists, who have since gone strangely quiet, reckoned that supply would flatten and then fall. We believe that demand, not supply, could decline. In the rich world oil demand has already peaked: it has fallen since 2005. Even allowing for all those new drivers in Beijing and Delhi, two revolutions in technology will dampen the world’s thirst for the black stuff.

The first revolution was led by a Texan who has just died (see article). George Mitchell championed “fracking” as a way to release huge supplies of “unconventional” gas from shale beds. This, along with vast new discoveries of conventional gas, has recently helped increase the world’s reserves from 50 to 200 years. In America, where thanks to Mr Mitchell shale gas already billows from the ground, liquefied or compressed gas is finding its way into the tanks of lorries, buses and local-delivery vehicles. Gas could also replace oil in ships, power stations, petrochemical plants and domestic and industrial heating systems, and thus displace a few million barrels of oil a day by 2020.
