Many of the wind turbines in Massachusetts automatically shut down over the weekend due to the blizzard, annoying but necessary considering ice buildup can hurt a turbine's performance just as much as it would an airplane's. (Notable exception: Ipswich Wind, which had its best two-day stretch of catching clean energy in at least a month.)
One of the more entertaining myths pushed by anti-wind activists is that after an ice storm wind turbines will start aiming chunks of ice at distant homes like a carbon-fiber eye of Sauron. Studies have shown that if a turbine continues to operate even during an ice storm, ice may fall up to 90 meters away. But that's about 4 times closer than any home should be from a wind turbine, so consider yourself safe. Just to be sure, take this advice from The Green Miles: Do not hang out directly under a 130-meter wind turbine during an ice storm.
As is often the case with wind turbines, people worry more about the new weird-looking thing than they do about the existing and actually dangerous thing. Just as people worry about made-up health impacts of wind power while overlooking the very real and very deadly impacts of our dependence on coal-fired power, they worry more about ice chunks from wind turbines that I can't find any evidence have ever hurt anyone when ice chunks from ordinary buildings will murder you dead.
