I see nuclear fission for public power generation as an old technology, that once showed much promise, but now creates more problems than it solves. I do not doubt that fission generation is fairly safe in the short term: there are heaps of reactors happily making power around the globe, and I would personally prefer to live near a modern fission reactor than the oil storage facility I currently live near. Major nuclear accidents at power plants have been relatively few and far between in the 50 or so years since fission power became mainstream.
Having said that, I don't see fission as an answer. Reactors create radioactive waste. Even in it's safest form, this waste can not simply be put into a landfill, and most folk do not want to have spent nuclear fuel anywhere near them. Of course, you can always have a reactor of a type that creates (for example) plutonium that folk may want to recycle into weapons. Nuclear waste is a big problem. I am aware that there are many people trying to mitigate this problem, but a big problem it remains. Also, proliferation. We are starting to see this now. Who likes the idea of Derpistan or the Democratic Republic of Duhgeria building reactors and dealing with high-level waste? If fission power is as feasable as proponents seem to think it is, what will stop them? Supply? Maybe, because uranium is a finite resource, that needs to be mined and processed, and there might not be enough for everyone who wants it.
Coal sucks. So does nuclear fission. There are no easy answers here, but there is a lot of energy flying around that we just have not worked out how to harness safely yet. More cash for R&D, less hostility for new ideas.
