Good. Time to build solar power gathering satellites and a laser to deliver the power to the surface.
It's actually a real thing with the gradual roll out of HVDC between countries. Eventually the gaps will be filled.

(And that’s assuming you get less than 60% losses going from electricity to light, through the atmosphere, back to electricity; and the ground station is free or negligible cost; and nobody worries about orbital death rays either malicious or accidental).
And (/s notwithstanding) people have considered floating PV on reservoirs to avoid evaporative losses.
Floating PV is pretty interesting, has anyone done it on a large enough scale for the economics/efficiency of it to be evaluated?
I don’t know enough about economics or statistics to answer your question, but here is a story about a pilot project: https://www.adb.org/news/features/inside-southeast-asias-fir...
Realistic in the sense of “if the $2 trillion per year currently spent on energy was spent on bootstrapping known tech but in space”, rather a lot more.
