Texas, technically, generates more TWh than California. I think a data center boom followed by a bust would help a lot more than what California can do. Unlike in cars, CAs market size or regulations can’t help/hinder other fuel sources as much.

Grid-connected PV in Texas has grown between 33% and over 100% every year since 2008, which outpaces the growth of solar in the US in the same timeframe.

California's percentage of solar generation as a share of the entire solar generation in the USA has shrunk every year since 2016.

It's not been accurate to say that California is dragging the rest of the country with them for a long time when it comes to energy generation.
