It makes a lot of sense, nuclear is nearly 100% reliable. Weather (wind) has wild swings. Solar is -pretty- good but can still swing around a lot and we simply don’t have the grid scale level of batteries that need to smooth it out. I’ve seen estimates that we need battery tech with 10-20x energy density(at current cost levels) what we currently have to make a viable replacement for classical energy sources (coal, natural gas, nuclear)
