Over the past 12 months, solar power has become California’s largest source of electricity, a trend likely to continue.

“In the 12 months ending April 2025, solar generated 83.1 terawatt-hours (TWh) of electricity, compared to 81.6 TWh from natural gas.”

“Nationally, solar generation continues to climb. In April, solar supplied 10.64% of U.S. electricity for the month (marking the first time the country crossed the 10% mark) and contributed 7.35% of generation over the rolling 12 months. California, by comparison, produced 42% of its electricity from solar at its seasonal peak in April, with May expected to push that figure even higher.”

Good 'ol CA, long-time nation-leader.
