California, known for palm tree-lined boulevards and the iconic Hollywood hills, is adding another claim to fame: renewable energy. And the Golden State could offer a glimpse into the crystal ball of Australia's energy future.

For the first time ever, California’s batteries took over gas as the primary source for supplying evening power demand in April, providing “akin to the output from seven large nuclear reactors” one evening, according to the New York Times.

These records were broken in the Californian spring, when there was plenty of sunshine without the summer heat that causes people to turn on the air-conditioning and consume more power, but it’s a sign of the shift underway.
