There is only one place wind power works. That is Yucca Valley, CA, where the wind blows fast and constant. Otherwise you will need replacement energy for when there is no wind.

There are lots of mills in the Altamont Pass region of the Bay Area in CA. The work swell.

However, they tend to dice a lot of raptor birds. Not Pretty. Most enviros hate them.

The tech is also problematic. They are prone to terrible problems with harmonic vibration and maintenance is an obvious issue with a huge motor on top of a 40 ft tower.

Specifically, you will need -- guess what? -- a carbon-based backup system for peak loads and wind-absent times.

On a nationwide basis, wind power is useful -- AS AN ADD-ON -- not otherwise. Same as solar in a lot of ways.
