> California: 83% renewable, dominated by solar

California's grid is pretty decently balanced. Solar isn't even close to 50% - so saying that it "dominates" is pretty misleading.

It's like ~30% solar, ~12% hydro, ~10% wind, ~10% nuclear, all other renewables ~8% (~70% renewable, including nuclear) -> ~30% fossil fuels.

Are you maybe only counting domestic production and not total consumption? Or are you looking at the best time of the year and not the full year?

Or am I looking at sources that are >1 year out of date and in one year they've jumped from ~70% renewable to ~83%?

AIUI, there has been excess solar at peak, but batteries have growing very fast. That might have caused a big change even in a year.

Nuclear is not renewable though, those isotopes were created when some past generation star collapsed as supernova.

  • And wood, coal, and oil are renewable. It's funny that we have fixated on "renewable" when carbon in the atmosphere is the problem, isn't it?

    • No, coal and oil is not. Since we have micro organisms that can consume wood, coal and oil will never be produced again.
