EXACTLY HOW MUCH CO2 DOES WIND POWER SAVE?

It is a complex question as this report to the UK parliament makes clear. What's more, no proper answer has been published by the UK government, so despite the massive cost of adding all the wind turbines to the UK there is no official way of knowing whether the savings are worthwhile, or indeed if there are any savings at all. In this piece on the Bishop Hill blog there is an account of a councillor in Scotland who is taking a case to UNECE against the authorities behind the wind farm policy (the EU and the UK) on the very point of inadequate information about CO2 savings among others. She has already won the right to have her case put and a ruling is expected next summer. If she wins it would be a fantastic victory, but I am not holding my breath.
