The drought doesn't really have to affect nuclear power's output. This is because of environmental regulation that requires that the plant keep a river below a certain temperature. Because apparently warming a river is worse environmental impact than climate change. Furthermore, many nuclear plants are cooled by the ocean or by waste water. Renewables require immense amounts of storage to even out intermittency. Even just building one hour of storage is 2,500 GWh globally. We'll need around 3 weeks of storage to make a completely renewable grid: https://pv-magazine-usa.com/2018/03/01/12-hours-energy-storage-80-percent-wind-solar/ https://pv-magazine-usa.com/2018/03/01/12-hours-energy-stora... We have no feasible way of delivering that much storage. Wind and solar are cheaper to make small reductions in a grid that is mostly fossil fuels. Their intermittency isn't an issue there because it's just opportunistically shutting down the fossil fuel plants when wind and solar are producing. But actually delivering a 0% carbon grid with intermittent sources is not just hard, it's not possible.
