We can't have diversity with just renewables and storage, because the large reservoirs and battery vats required for it won't be built or require so much material it invalidates whatever emissions savings went into it. Wind and solar are nice to have, but all of them exist with gas as baseload power and gas can only be replaced by nuclear or coal. Since we're theoretically banning coal, this leaves nuclear as a required element.

China has already discovered this with their new next-gen coal plant construction program. PV-onlyism won't work. And really, why should we constrain ourselves that way anyway?

We have or will have N types of renewable generation (hydro, solar PV, solar-thermal, solar-hydrogen, wind, wave, tidal, geothermal, maybe biomass, maybe some kind of engineered plant things generating electricity, who knows) and M types of storage (pumped-hydro, thermal, P forms of chemical battery, hydrogen, gravity, flywheel, bio-fuel, compressed-air, who knows). Fairly soon they will give us costs lower than nuclear, and far less climate damage than fossil. We won't be "constraining" ourselves much by using a mix of the best choices, instead of trying to keep an also-ran tech such as nuclear on life-support.
