The Rational Optimist (P.S.)

by Matt Ridley

a clutch of coal and nuclear power stations and a handful of oil refineries and gas pipelines supply the 300 million Americans with nearly all their energy from an almost laughably small footprint – even taking into account the land despoiled by strip mines. For example, in the Appalachian coal region where strip mining happens, roughly 7 per cent of twelve million acres is being affected over twenty years, or an area two-thirds the size of Delaware. That’s a big area, but nothing like the numbers above. Wind turbines require five to ten times as much concrete and steel per watt as nuclear power plants, not to mention miles of paved roads and overhead cables. To label the land-devouring monsters of renewable energy ‘green’, virtuous or clean strikes me as bizarre. If you like wilderness, as I do, the last thing you want is to go back to the medieval habit of using the landscape surrounding us to make power. Just one wind farm at Altamont in California kills twenty-four golden eagles every year: if an oil firm did that it would be in court. Hundreds of orang-utans are killed a year because they get in the way of oil-palm biofuel plantations. ‘Let’s stop sanctifying false and minor gods,’ says the energy expert Jesse Ausubel, ‘and heretically chant “Renewables are not green”.’
