The biomass problem, or fallacy, is well-known and media like The Times are finally catching up.
Britain is wasting hundreds of millions of pounds subsidising power stations to burn American wood pellets that do more harm to the climate than the coal they replaced, a study has found.
Chopping down trees and transporting wood across the Atlantic Ocean to feed power stations produces more greenhouse gases than much cheaper coal, according to the report.
It blames the rush to meet EU renewable energy targets, which resulted in ministers making the false assumption that burning trees was carbon-neutral.
Green subsidies for wood pellets and other biomass were championed by Chris Huhne when he was Liberal Democrat energy and climate change secretary in the coalition government. Mr Huhne, 62, who was jailed in 2013 for perverting the course of justice, is now European chairman of Zilkha Biomass, a US supplier of wood pellets.
The report was written by Duncan Brack, a former special adviser to Mr Huhne, for Chatham House, the respected international affairs think tank. Britain is by far the biggest importer of wood pellets for heat and power in the EU, shipping in 7.5 million tonnes last year, mostly from the US and Canada.
Drax, Britain’s biggest power station, received more than £450 million in subsidies in 2015 for burning biomass, which was mostly American wood pellets.
The report says that the government’s assessment of the impact on the climate of switching from coal to wood pellets is flawed because it ignores emissions from burning pellets in power stations. The assessment counts only emissions from harvesting, processing and transporting wood pellets.
