I think Bill Gates has a fairly balanced view of the energy needs/wants. At least that was my takeaway from reading his most recent book. I could see why we need fission energy even if we eventually find better ways of generating/capturing energy.
I don't think he is and taking his book which advertises his investments as a base for argumentation is kinda...fishy.
I linked several studies which clearly demonstrated that investing money in nuclear energy is not only a bad idea financially, it also hurts the fight against global warming because you can spend every $ only once.
BG has always been very clever, but historically that has meant clever at benefiting BG at our expense. PR finesse notwithstanding, I don't expect that has changed.
