that makes me doubt him as he obviously doesn't factor in the enormous difficulty of nuclear waste. nuclear energy is not green at all.
EDIT: Also that was in 2004 and things have moved on massively since then
Scientist that he is, I very much doubt that he didn't factor it in. (You may disagree with his conclusions).
I see it as a well-understood technical problem with well-reasoned technical solutions. But the politics of "what so we do with the waste?" are basically self-sustaining now.
