Does electromagnetic radiation from wind turbines pose a threat to human health?

Electromagnetic fields (EMFs) from wind turbines are well below international exposure safety limits.

Wind turbines produce EMFs mainly from their electrical equipment. Multiple studies have found their strength to be lower than everyday exposure to many common household appliances, such as microwaves and vacuum cleaners. 

In a field study at a Canadian wind farm, average magnetic fields at the base of operating turbines were around 0.1 microtesla (µT) and dropped to background levels within 2 meters. Turbines under high wind and low wind conditions emitted equivalent levels of radiation. Another 2020 study found wind turbines produced under 0.1 µT at 4 meters distance.

For comparison, an electric can opener measures about 60 µT at 6 inches but 0.2 µT at 4 feet. International guidelines set a safety reference level of 100 µT at 50 Hz, far above the turbine measurements reported in field studies.
