> There is a worse problem here - heat causes electric power demand to rise. No gigawatt-scale power grid anywhere on the planet has supplied increased demand through renewables.

I expect that, for India, the solution will be to build a thousand megawatt-scale power grids, or, more likely, millions of sub-kilowatt-scale power grids.

Connect a solar panel to a battery and an AC unit, and you have a standalone AC unit that works whenever there’s lots of sun, and in India that correlates reasonably well to ‘whenever it’s scorching hot’.

With solar already cheaper to build than running _existing_ coal plants in India (https://www.renewableenergyworld.com/solar/report-its-now-ch...), I expect that to even be economical, even if such standalone units waste energy if there’s sun but not need for AC.
