The Solar-Panel Backlash Is Here
In Los Angeles, where I live, the rites of autumn can feel alien. Endless blue skies and afternoon highs near 90 degrees linger long after Griffith Park opens its Haunted Hayride. When the highs dip toward more seasonably appropriate numbers, they’ll be accompanied by one of California’s unfortunate traditions: wasted clean energy.
During the fall and spring, cloudless afternoons produce a spike in solar power at a time when milder temperatures necessitate less air-conditioning. When that happens, the state’s solar farms make more energy than the state can use, and some panels are simply turned off. This maddening problem—a result of what energy wonks call the —has been getting worse as the amount of available solar power the state’s ability to move that power around. In early 2017, just more than 3 percent of the state’s solar was wasted this way. The total reached 6 percent by 2022, according to , and in the early afternoons of March
