When I last interviewed James Lovelock in 2010, I provided here online fuller quotes of his key points than the print edition of the interview would allow. As it proved popular with readers last time round, I have taken the time again to transcribe his responses...
Lovelock on "fracking":
Gas is almost a give-away in the US at the moment. They've gone for fracking in a big way. This is what makes me very cross with the greens for trying to knock it: the amount of CO2 produced by burning gas in a good turbine gives you 60% efficiency. In a coal-fired power station, it is 30% per unit of fuel. So you get a two-to-one gain there straight away.
