Burning wood instead of coal in power stations makes sense if it's waste wood

The environmentalist and advisor to Drax power station, Tony Juniper, says the wood used to create energy can be coppice thinnings and waste material

Last week, a group of respected scientists wrote to the Guardian to argue that using wood to generate electricity in place of coal is not a solution to climate change. Their critique pointed to a "carbon debt" arising from the years between using a tree for fuel and new one growing. They gave the impression that forests are being cleared wholesale to be shovelled into power stations. Reality on the ground is, however, somewhat different.

I found this out when earlier this year I went to the USA as an advisor to Drax, a power company in the UK that is seeking to accelerate the phase out of coal by using a biomass instead. On my travels I had many vivid reminders as to how forests are more than collections of individual trees. In the case of the US South, from where much of the wood being used in the UK comes from, I saw vast expanses of production woodlands being harvested for a range of products.
