The Greens are the greatest impediment to any sensible energy policy. In order to regain sanity, they need to lose their sheen. The best way to do that is to give the extremists what they want.
A couple of years ago protesters attempted to close Draxhttp://www.independent.co.uk/environmen ... 14071.html
It seemed to me at the time and more so now that a wise government would have "allowed" the protesters to storm the power station and shut down the grid, thereby causing a blackout across Yorkshire, at least. The government could have shared the pain by revolving power cuts across the regions of Britain, while it attempted to peacefully remove the protesters. Ordinary people would have been angered by the self righteous action of the protesters and as that anger grew they would have sanctioned forcible removal. Result: the Green movement discredited, at least at the extremes.
It's not inevitable that the Conservatives take the flak (assuming they are in power when the lights go out), providing they prepare the ground by continually warning about the consequences of current policy. Not that I expect them to do this of course.
