What I find odd is that it has to be an all-or-nothing approach. Maybe sunny areas can do more with solar, great! But that won't work everywhere, and probably isn't a complete replacement anywhere. Other places that are cloudy, it might be better to go nuclear. Or even gas.
The regulations and the subsidies ought to be removed though, let the market decide. Solar or Nuclear will win if it's better, and that might be a per-area contest.
This also means that, globally, renewables are much cheaper than nuclear in most places. In a global economy, energy intensive industries will migrate to these renewable-rich regions as fossil fuels are phased out. The relative energy ghetto regions will not save their heavy industries by going nuclear.
Obviously using used car batteries might be a way to recycle these more effectively than what is currently available.
