Simply consider the case of China. They install and export more solar PV than anyone else in the world, and they are aggressively building out wind as well. It is literally impossible to get a better price than China when it comes to renewable energy, yet for some reason the Chinese have decided to dump tens of billions of dollars into nuclear energy.
We've been effectively spoiled with this capability, and we need to be weaned off quite abruptly. Just because we've been spoiled and expect the grid to give us on-demand energy in the middle of the night, doesn't mean we have to continue doing so.
That said the growth in renewables will still take some years to make a big dent in coal in China so the nuclear power is welcome!
