Even at 2am on a still night the UK uses a gargantuan amount of power and we haven't solved the "How do we manage that with renewables?" problem.




In some areas like Texas wind blows strongest at night. And generally wind and solar compensate each other's seasonal deficiencies. The biggest problems are the 3 weeks in a year in which the sun does not shine and wind does not blow at the same time.


I read an article by Ramez Naam that suggested this would be solved by a nationwide grid rather than separate grids, since weather and usage fluctuations will average out


In fact, wind power generates such an energy surplus on the Texas grid that various energy retailers have gone with “free evening electricity” plans. Possibly only applicable to Great Plans-style regions, but solar+wind gives a pretty reliable generation base for Texas.
