Reliable solar power for $40/MWh:

And it requires the exclusive use of very favourable terrain (for solar, which isn't available in many places) to provide what, 1/5th of what same sized nuclear facility could do (and that's me underplaying the capacity of the nuclear facility, it's even worse if you go for what's possible)

Location doesn't make as much difference as you would think. Arizona gets about 3 times as much sun as Boston does, but a cloudy day in Arizona isn't significantly different than a cloudy day in Boston. And if you size your solar to support cloudy days...

And yes, solar farms are bigger than nuclear plants. That might be a problem in Singapore, but a few hundred square miles of solar farms is not a big deal in a country with 3.5 million square miles.

So it can provide piddling amounts of power given very favourable conditions.

Now consider that Boston is on similar distance from North pole as Spain, and not everywhere has huge swaths of unused land conveniently stripped of natives.
