In southwestern Minnesota there is a virtual forest of wind turbines along a supposedly very windy ridge. The wind turbines extend virtually from horizon to horizon. I frequently drove by this wind turbine forest and often observed times when not one of these scores of wind turbines were moving. Only rarely were all moving presumably producing electricity, but it was common even on windy days to see at least some of these turbines sitting idle producing not a single watt of electricity. To depend on such a fickle source of electric power is pure folly.
If the wind is too high, they lock them down so they don’t turn.
