New construction of nuclear plants is constitutionally limited in California and has been since well before I was born. Existing capacity is just leftover from before that era.
That might be a possibility, but Iām going to go out on a limb and suggest that it is actually pretty pathetic we have to import power to make up our energy needs at all.
When I last looked at the stats a few years ago we were importing about 30% of our power from other States and it was trending upwards.
