Not everyone has hydro resources to use. It's much easier to have access to sun or wind.
Nuclear needs (nuclear) fuel, and its extraction is largely centralised.
Decentralisation is key.

Lol. What about the coal panels from china? Sourcing (95% !) the most critical resources from a murderous communist regime doesn't sound that great either.

You don't need that much fuel either... And once these small reactors are mass produced, swapping them out every 20 or 30 years doesn't sound that bad to me.
Solar exists today.
Keep waiting for those small nuclear reactors.
Considering they arrive some day, and they are affordable, do you really think any homeowner in South America, Africa or Asia would be allowed to have them at home?
No way.
Solar could be used right now in lots of places.
Solar is the most decentralised energy source right now.
No permission needed. Install and use for several decades.
