Good that you are positive about the possibilities, thanks for posting.
There are some recent developments which change everything to be even better.
Hydrogen fuel cells are a kind of battery which generates hydrogen from solar energy.
These can be used to keep the power of a solar or wind installation producing power 24/7. In the case that too much solar is produced, the unused power is converted to hydrogen fuel, which is a clean replacement of fossil fuel.
The other thing is a Bitcoin or other proof of work token minting datacenter.
This generates valuable proof of work tokens from sunlight, or wind energy, which can be used to maintain and scale the facility with no expense.
