Our president is a global warming denier, is anti-vaccine, and is a conspiracy theorist. Regardless of where you are on the political spectrum, being anti-science is never a good thing. When those in positions of power are ignorant of science and hostile to the institutions of science and the methods that those institutions espouse, that is a recipe for disaster. But even a stopped clock is correct twice a day. And even though there appears to be a significant asymmetry in the degree to which our two major political parties take anti-scientific positions, on some issues the political left has it wrong for their own ideological reasons. The two big anti-science issues popular on the left are anti-GMO stances and anti-nuclear energy. The latter was recently brought into sharp relief when Trump signed a, "Memorandum on the Effect of Uranium Imports on the National Security and Establishment of the United States Nuclear Fuel Working Group." //

Nuclear power is the safest form of energy we have, if you consider deaths per megawatt of energy produced.

Nuclear waste can be dealt with, and the newer reactors produce less waste, and can even theoretically burn reprocessed waste from older plants…

This is also the option most likely to succeed. We do have examples from other countries. Germany tried to go completely renewable and closed their nuclear plants, and now have to build coal-fired plants to meet their energy needs. Meanwhile, the countries that are doing the best with low carbon energy are France and Sweden, who invested heavily in nuclear. This is why Bernie’s plan would be a disaster, it would exactly follow the failed strategy of Germany, but on a larger scale.
