California Was Mostly Solar-Powered In May — A Global First

"No major economy had previously received over half its electricity from solar across an entire month. Thank the mild, sunny spring weather, and batteries."

"While the Trump administration is busy pointing out that the sun doesn’t shine at night, solar is breaking records around the world, including in sunny California.

Solar panels produced 51% of California’s electricity in May, the first time the clean energy source surpassed the halfway mark for an entire month. The data counts both large-scale installations and the state’s bounty of rooftop arrays.

This isn’t just a milestone moment for California; it’s a milestone for the entire world. Think tank Ember says the state is the globe’s first major economy to cross the 50% threshold. (Hungary, at 47% in June 2025, is knocking at the door, though it has a far smaller GDP.)

Solar’s rise has helped California cut polluting energy sources out of its power mix. Natural gas is the only fossil fuel that California power plants burn at appreciable levels, and solar is steadily squeezing it out of the system. Case in point: Solar outproduced gas not only during its record month of May but throughout every month in 2026 leading up to it, too."
