> 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1 year out of date and in one year they've jumped from ~70% renewable to ~83%?

EIA puts this out daily:

https://www.eia.gov/electricity/gridmonitor/dashboard/daily_...

Today was 31% solar, 16% wind, 16% hydro, 6% geothermal, etc.

Some of the difference to your numbers will be seasonal/weather-related, but the pace of solar and wind installation is such that data that's even a year or two old can be wildly out of date.

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

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.
