Nuclear was blocked by public perception. See my earlier comment.

I see no reason big oil can’t pivot to green energy. They’ve got the money, the experts, the lobbyists, the infrastructure, everything.

And I suspect they will, once public opinion and reality bites hard enough. Just like big tobacco saw the writing on the wall after public perception turned and they got their ass handed to them in the courts. They quit playing like their product was safe, or in any way OK, and started in on ecigs.

(I may be full of shit on that last point, in case anyone can correct me.)
