California likes to pretend it leads the nation in decarbonizing its power grid but has been out 'greened' by an unlikely state:

Since 2018, Texas has surpassed California and the national average in integrating renewable energy sources like solar and wind, thus becoming a frontrunner in the efforts to decarbonize the grid. This contradicts the popular narrative that California, with its progressive leadership, is the champion in this field.

Bloomberg explained why Texas is now the "king of clean energy": 

In Texas, solar permitting is uncomplicated. Connecting projects to the electric grid is straightforward. Then there's cheap labor, homegrown energy expertise, plenty of sunshine and an anything-goes ethos. "There's no 'Mother, may I?' here," says Doug Lewin, who worked in the Texas Legislature on energy policy and now advises power companies. "In Texas, it's just easier to get things done."
