The San Gorgonio Pass wind farm is one of three major wind farms in California, the other two being at Altamont Pass (near San Francisco) and at Tehachapi (near Bakersfield).  Wikipedia says there were 3,218 wind turbines at San Gorgonio Pass in 2008, generating 615 MW of power.  Currently there are over 13,000 wind turbines in our state.  This pic was taken from the observation deck at the upper terminus of the Palm Springs Aerial Tramway.
