Batteries are growing on the grid to handle evening power use surges when solar peters out. California just hit 7GW out of 10GW capacity. Our house is battery powered from 4 p.m. to 9 p.m. and will be part of a virtual power plant soon.
Today batteries help with daily peak shaving; longer gaps in solar/wind production are harder. #FusionEnergy could help with that but is only one part of the overall solution. https://www.nytimes.com/interactive/2024/05/07/climate/battery-electricity-solar-california-texas.html
