Right now everything looks set for continued exponentially-shaped curves on renewables deployment, which will drive coal and eventually the majority of fossil generation out of the grid. None of that is happening in nuclear, unfortunately.
UK is a misleading example since they’re also using 20% less electricity since the 1960s (https://ourworldindata.org/energy/country/united-kingdom), probably due to their struggling economy. By comparison the US has increased its consumption by 1.6x. And even UKs data will turn out to be worse if they actually switch to EVs because that’s going to increase demand on the grid.
Yes, solar can supply a lot of daytime power as China has demonstrated. But all that daytime power generation is wasted for nighttime power needs. So overbuilding solar in that way will mean super cheap clean energy during the day and super expensive dirty energy at night (because that dirty energy will no longer have daytime demands). And the dirty power will be dirtier since it’s going to be plants that can spin up quickly instead of the baseload ones that are always on. Think about it logically - if solar was solving all their needs, why is China investing in turbocharging their nuclear industry? Answer: because baseload and a reliable backstop to the grid is super important and valuable and batteries won’t cut it to completely decarbonize the grid.
Renewables are popular because fossil fuel companies don’t find them objectionable - it’s a much gradual off ramp from fossil fuel dependence in the grid than with nuclear. And unlike nuclear, fossil fuels remain in use to handle low energy cases from renewables until batteries magically get good enough for the grid.
You are offering this as a fact, but the fact is incorrect.
