The world dominion of western thought, forms of organisation, technology and military force is not God-given, nor eternal, nor greatly appreciated by the rest of the world.

Europe and North America, we are told, are less dependent on energy-intensive heavy industry than in the 1960s and 1970s. It seems we squeeze more GDP out of a barrel of oil than in those benighted days.

There are signs that the age of petroleum has passed its zenith. Adjusted for inflation, a barrel of crude oil now sells for three times its long-run average. The large western oil companies, which cartellised the industry for much of the 20th century, are now selling more oil than they find, and are thus in the throes of liquidation.

Of all the failed technologies that litter the onward march of science - steam carriages, zeppelins, armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.
