Ugh.
At this moment, 74.2% of California’s electricity is coming from renewables, overwhelmingly solar. Nearly 8% of new cars sold in the US are electric, a similar number of total cars on the road are electric. In ten years it will be nearly 100%.
- throwup238 2y ago> At this moment, 74.2% of California’s electricity is coming from renewables, overwhelmingly solar. It's even better than that! The rest is mostly nuclear and hydro so at this moment only 12% of California's power supply produces significant amounts of CO2 [1].

- fcccccbjjv 2y agoUnless I'm missing something this is the instantaneous generation, ie it needs to be averaged over 24hr (actually over the year) to get a real picture of CA's energy mix. (Also, I wouldn't put hydro in the clean energy in CA)
- jvanderbot 2y agoIt's a bit misleading to say Hydro doesn't tackle climate change, though it is environmentally unfriendly. One particular political party loves to make jokes about "clean" energy, by conflating different definitions of clean. Generally, I think it's fair to say climate change is the biggest concern, so I am comfortable when "clean" or "green" refers to CO2 free.
- fcccccbjjv 2y agoMy concern with California hydro is the water wastage. Nothing excuses the amount of water California wastes.
- fcccccbjjv 2y agoAre you sure? This link from 2021 says the net power consumed in CA was less than 34% renewables, and the in-state generated renewables are about the same. https://www.energy.ca.gov/data-reports/energy-almanac/california-electricity-data/2021-total-system-electric-generation https://www.energy.ca.gov/data-reports/energy-almanac/califo... EDIT: pedantic physics moment. When I say "power" consumed I actually mean the time integral of power over the course of a year, i.e. energy, expressed as GWh
- colechristensen 2y agoI wrote "at this moment", which meant instantaneously, not overall, or for 2021 as there has been very fast buildout. Data can be found here: https://www.caiso.com/todays-outlook/supply https://www.caiso.com/todays-outlook/supply It has gone up a couple of points since I posted.
- fcccccbjjv 2y agoMissed that in your comment, sorry. That being said I find the avg to be the only interesting metric (unless you build power lines)
