This report says that "SCE leads the nation in renewable energy"
… and I believe them. For one thing, Southern California is not only well provided with sunshine, it is quite well provided with tectonic advantages, because it's not too far from the "Ring of Fire".
You may have noticed that the installed capacity of the wind component is much larger than the geothermal, but it delivers appreciably less energy. If you transfer their data to a spreadsheet, you will find that the "capacity factor" for the geothermal is slightly over 91% whereas that for the wind turbines is just less than 28%. The 78% for biomass is consistent with the burning of any fuel, except that presumably this small quantity is being renewably grown.
If so, it means that nowhere else in the nation can we expect to get as much as 10% of our electric energy production from non-geothermal "renewables", for quite a long time. But global warming, not to mention the acid pollution of nitrogen and sulfur oxides, and the emission of neurotoxic mercury vapor, implies that we need to replace all of our coal and natural gas burning far sooner than that.
