The most important question is if wind and solar capacity can come online sooner than nuclear in order to slow down stop global warming, which is estimated to cause 250,000 deaths/year worldwide 2030-2050 by the WHO. Solar and wind were only 9.2% of the U.S. total in 2018 and the US has very good conditions for them. Solar energy will have a harder time replacing base load plants. It might work out fine in the US but how about other countries? I think both renewables and nuclear will be needed. Carbon caputre technology would need to be ~5 times cheaper than currently to be viable.
