What are those structures on the ground? That's a windfarm isn't it?

Yes indeed - those are windmills.

The afternoon wind in the desert passes is reliable and strong, thus the wind farm.

Another place in California with lots of them is Altamont Pass between the Bay Area and the Sacramento Valley. This is the world's largest wind farm.

The wind blows ONSHORE in the morning (light breeze), and back OFFSHORE in the afternoon (strong breeze).

But the strongest winds are found at Tehachapi Pass in Southern California, north of LA. The windfarms there are actually profitable; the wind HOWLS through Tehachapi Pass almost constantly.
