Scottish Power has announced that it is going to convert two of its coal-fired power stations to burn wood - coppiced trees in other words. They aim to replace fully 5% of their coal requirement (that's their coal requirement, not the country's coal requirement, mind) with this "carbon neutral fuel".

In order to do this, they need to use 12% of the agricultural land in Scotland.

So it's an expensive, but meaningless gesture.

Update:

It's a very expensive meaningless gesture. According to this, biomass fuel is more expensive than oil or coal, even if set-aside subsidies are still paid!! It's daylight robbery!
