The document discusses hazards from wind turbines in cold climates, particularly the risk of ice throw. It analyzes ice throw probabilities at different distances from turbines when operating and not operating. For the public, risk of ice throw is comparable to other low probability risks like lightning strikes. For service staff, the risk of injury from ice is lower than risks from traffic accidents. The document recommends using ice detection systems, active heating, or passive de-icing equipment to reduce risks from ice throw during cold weather operation of wind turbines.
How dangerous are wind turbines in cold climate regions? Can we do something about it?
