Solar is only half the battle though. There can often be a severe electricity shortage in the evening when solar power shuts off but temperates are still high. This issue is greatest in the late summer and fall because it’s still very hot but the sun sets earlier.

There are solutions to this issue but they are fairly early in development and sometimes expensive. California is struggling with this issue currently. We’ve installed a huge amount of battery power over the last few years which has prevented several catastrophes so far but heat continues to get more severe, increasing energy needs as we are trying to shut down the state’s remaining gas peaker plants.
