I don't have much knowledge of the issue, but couldn't it be that big investments in nuclear energy would propagate and facilitate the process of isotope separation for enriching Uranium, which would mean more countries having the technology to build nuclear weapons, and thus increase the risk of nuclear war, and ultimately human extinction? This stuff sounds scary to me, not the energy part
