My comment was mostly tongue-in-cheek, but also the time-value of money on constructing a new nuclear plant is a very real problem. Yes, we should be using a massive, mature, and mostly-carbon-neutral energy source. However, due to economic factors, we can build a lot of renewables capacity before the site planning is even done on a new nuclear power plant. It’s a lot easier to finance a new renewables facility that is generating revenue pretty quickly.
