I looked this up yesterday, and figure it would be interesting to folks who are perusing these threads.

Power generation capacity with breakdowns by type and import for the state of California.

The most fascinating point I saw is that the total power generation capacity effectively hasn't changed since 2001.

I suspect this is a theme in the western world globally.

Energy demand over that time is down in the developed world - the UK for example peaked in 2005 at ~400 terrawatt-hours to ~330 terrawatt-hours in 2021 (with >10% increase in population).

Edit: I dont expect this trend will remain, cars switching from liquid fuel to electricity and heating from gas to electricity is going to accelerate at some point and cancel the efficiency savings.

Interesting: geothermal is an order of magnitude more than I would have guessed.
