Solar and wind are nice, but they don't solve the base load problem. They aren't consistent enough to operate as base load on a power grid. They are certainly convenient for maintaining peak load, but without solving the energy storage issue in parallel to the added capacity, we need alternatives.
Then comes storage, curtailment, and backup (always necessary: fossil-fuel plants always produce around 9% of electricity in fully-nuclearized France).
Moreover backup is now provided thanks to gas turbines, and we know to run them thanks to hydrogen (clean), which can be green hydrogen (cleanly produced thanks to renewable sources overproduction).
There is no need for each location to deploy each and every type of production unit: each region has its own geography and preferences.
Those benefiting from huge potential for hydro, offshore wind or solar (deserts...) are at an advantage.
Those benefiting from a low production time-profile correlation with most other ones also are blessed.
Those totally unable to deploy anything probably don't need huge amounts of energy or are rich to the point of already importing it (is there a counter-example?).
