One thing holding back solar-panel everything, on top of every single roof, is battery technology that costs the same per-pound as cinderblocks. There has to be a 4000 pound battery hiding inside of every single house, hiding under every single telephone pole. And that bullshit needs to last 30 years minimum, it needs to not degrade on daily deep cycles, it can be as heavy as you want but it has to be cheap and easily made by robotics and not have too much rare earth metals.

Until then, you're stuck to Hydro Dams, Nuclear Power, Coal fired electricity, then Natural gas, Petroleum being 96% of all electricity.

That non-descript factory building making widgets, the electric draw on that thing is the surplus from ten thousand full size rooftop solar arrays.

Your Solar revolution will have to wait for batteries to do a gain of function like the large language models did.
