Suppose nuclear requires various government supports to make the projects economically viable and in research for new reactor designs. Now suppose we put that same money into subsidizing renewables, and building a modern grid. Which one gives a better result? Edit: to add an even spicier question, why not keep renewables + natural gas with carbon capture?
