I left out the geothermal.
A few years ago I visited the Geysers, to do a security analysis of the telephone system. Kind of an anti phreaker thing.

shows a highly seismic area around Clearlake. That is the Geysers.
We have big time wind farms. Check out the financials before hanging your hat on them.
Over in the East bay is a major wind farm and the one on the Tehatchapi (sp) mountains is massive.
These are not the windmills of the past. The pitch of the blades, the efficiency of storage, conversion, all very well done.
The design variance is fantastic. One is a single shaft with the hub in the middle. one is a 3 blade affair. One looks like an egg beater. All are cutting edge.
