solar is pointless for a main power source
geothermal is the answer. it’s everywhere. absolutely clean. and the ‘fuel’ is just water being boiled at the bottom of a 6+ mile shaft... the resultant steam comes up other shafts which turns a steam turbine which can produce 1+ gigawatts of power.
extra bonus... we wouldn’t be beholden to china for any of it.
And how much does it cost to drill that 6+ mile deep hole?
Sorry, no deal.....build nukes.
We have tried that. Limited success.
The problem with geothermal is that the hot zones are usually mineral laden. So no matter if you use natural steam or inject water, you get VERY high concentrations of mineral. These either deposit themselves on the surface of anything that is exposed to the steam, or acid and other chemical treatments have to be done to keep the minerals at bay.
Ordinarily the steam and condensate would have to be treated before disposal, but the EPA and DOE have given these sites exemptions.
Even then they are not very profitable once the cost of maintenence and component replacement are factored in to the equation.

In principle it’s simply too simple to garner attention from the big solar and wind types.
