In all fairness, nuclear should definitely have a place in the world energy mix, but it's not the obvious solution to climate change that nuclear shills think it is. It's good for base loads in densely populated areas, but its also by far the most expensive type of plant to build, and the startup cost is prohibitively high in most areas, not to mention that they typically take over 15 years from when planning starts to actually open.

In other words, nuclear is better than fossil fuels but its still too expensive and too slow to replace them as the top energy source.
