1 California derailed its booming rooftop solar buildout. Can it be fixed?
Over the past year, California regulators have kneecapped small-scale solar needed to hit the state's climate goals. These lawmakers are trying to bring it back.
A mountain of solar, storage, and wind projects are waiting for permission to plug in. The interconnection queue is now double the size of the entire U.S. grid.
