Electricity from "renewables" in the US is about the same as from nuclear (counting hydro as the former). The simple ratios are 20% coal, 20% nuclear, 20% renewable, and 40% NG in very round numbers. The issues with nuclear are well known, build time, cost overruns, etc. I have some hope for small modular reactors in time. maybe.
I tend to doubt another large nuclear power reactor gets built, Vogtle 4 may be the last one.
