I second Jerry's comments.
One of these days I need to re-visit Patterson Pass, north of Livermore and not far from here, but not in a direction we travel much nowadays. There was an article in the local newspaper recently explaining the massive upgrade program underway; Much fewer of the new style wind generators to produce the same power as the old ones. Part of the rationale was the reduced threat to raptors, and the reduced maintenance of fewer generators.
Prior estimates of the number of wind turbines in this area range from 5,000 - 10,000, with 7,000 being the number most frequently mentioned when we lived in Livermore, south of the wind farm(s). Having driven over and around the hills numerous times over the last 30 years, I don't doubt any of the numbers, although I've never stopped to count them.
