California has four good on-land wind areas, and there are big wind farms on all of them. Time to look elsewhere.

The floating Hywind turbines are tethered to a sea floor depth of 130m, but this technology is fairly recent for wind turbines.

Here’s a recent study on the potential off the California coast:

There is a ton of offshore oil in Southern California, so one would think that it would be straightforward to add wind. However the laws are such that existing practice is privileged and allowed, and changes are easily challenged by only a tiny number of people. So we will see if CA is able to deploy anything new off the coast.

There was a lot of offshore drilling before 1969, before blow-out protectors were required, until one big spill at the cusp of the environmental movement turned most of the California coast against oil drilling, and anything like it offshore, even, ironically, off-shore wind farms - for now.
