> They shut down the nuclear pathway and pushed "renewables".
Part of it is due to Diablo Canyon. And I agree that shutting down existing nuclear is a questionable idea given that the majority of the cost is upfront. As for why it wasn't pursued further, one only has to look at the absolute bungling of Vogtl or Hinkley point.
Part is due to forest fire measures (as are the blackouts) [1].
They also still use a large amount of natural gas[2], which is particularly expensive in the state.
