Killing power production in CaCaLand is a deliberate act — to appease the treehuggers out this way. Sustainable energy is OK so long as total need is backed up by reliable baseload. However, this condition is too “nuanced” for any liberal to understand. To a commie like those in charge it is heresy. The “sustainable” projects are for money laundering — taxpayer subsidy $$ are skimmed by those who approve and then require.
As to buying from out of state, that is part of the law. In state, regulations cripple energy production. But, energy that comes over a border, regardless of how it is generated, is not regulated in the same way. This automatically makes it cheaper. That is why, 20+ years ago, every power utility built power plants in other states so they could sell over a border or two.
California needs to build several generators run by squirrel cages. Place these tree huggers in them and see if they can make a watt.
