Out of all major energy sources, nuclear is the safest
I believe the politicization of nuclear energy  (the resulting lack of investment & innovation) will go down as one of the major blunders in human history.We'd be in a far, far better situation with greenhouse gasses if we (as a human race) had continued to invest in nuclear energy.  There would have been mishaps along the way, but at a much smaller scale than we're experiencing now with deaths from air pollution and looming risk of a warming planet.We'd have much, much safer systems with modern reactor designs.
