This particular proposal is based on the idea that if renewables are cheap and getting cheaper (which they are) then you should build a lot of them.

They claim the lowest cost model for generating 100% renewable involves 5x the capacity being built.

However, they recommend rolling out 12x because that would provide another 500Twh of energy for only a 20% increase in spend (while reducing the amount of battery needed by 50%). A concept they have cheesily named "superpower".

Welp, they sure are cheap when made by mostly-coal-based China.

China is both mostly coal and also installing PV onto their own grid faster than anyone else.

China is also building nuclear power faster than anyone else.

Good for them.

While nuclear is one of the most expensive electricity sources, with surprisingly limited fuel reserves given the energy density, it's incredibly safe (despite the reputation) and I think there is inherent value in a diverse supply that can make up for the sticker price.

Also, China is able to build it at a reasonable price (~$40/MWh). It's not destined to be expensive, the price is just a consequence of excessive safety precautions.
