This summer, National Grid estimates that maximum and minimum energy demand from utilities is likely to fall to an all-time low (paywall). Peak demand is predicted to be 35.7 gigawatts, compared with 37.5 gigawatts in 2015, and minimum demand to be 18.1 gigawatts, compared with 18.4 gigawatts in 2015.

Meanwhile, on March 11  more than half the power needs of the entire state of California came from solar power for a few hours that day, according to the US Energy Information Administration (EIA).

Just 15 years ago, the state produced almost no power from solar at all.
