I note that you are a lost cause in terms of the energy debate Tom regardless of the facts. Not to worry you're not alone. I'm guessing that you are a Guardian reader.
Strangely enough earlier this afternoon I watched the Daily politics where the interviewer ended up making Philip Schofield look like Jeremy Paxman. It was such a soft interview that I wouldn't even call it a sofa interview - more like a stoney bean bag interview.

When asked how much energy windmills produced, without blinking or swallowing the bile building up in his greedy little throat, he announced "Ten percent"!.
I'm much to polite to call him a liar but......
