If the wind is too high, they lock the blades so they don’t rotate.
It doesn’t matter what they do in the high wind or ice. THEY DON’T WORK, and it is a scam. The POLITICIANs get a kickback on every one erected, ordered and delivered. It is a slush fund. Even if effective at delivering power at inexpensive reliable rates, let it rise or fall ONLY on if it can beat the competition of Coal, NG, Hydrogen, Gasoline, Diesel, Hydro, Solar et al. Measuring by the false scale of “is it saving the Planet” is using the language of our masters. BREAK OFF YOUR CHAINS, and do something besides blather on. We have been in the know of it being a scam for 20+ years, and the beat goes on.
