Matt Ridley has ripped into the biofuels debacle in an op-ed for the Times.
...there is nothing carbon-saving about bio-energy. Take wood, a more carbon-rich fuel even than coal. As the environmental scientist Jesse Ausubel, of Rockefeller University in New York, has shown, when you burn wood more carbon dioxide is emitted than from coal for the same amount of energy.
Yet Britain is dashing to replace coal with wood. Many coal plants are being subsidised to switch to biomass. Drax in North Yorkshire, the country's largest power station, is switching partly from coal to biomass while Eggborough, in the same county, will convert fully to become Britain's leading renewable power plant.
