Noise from wind turbines poses no threat to human health

Though many neighbors of wind farms complain that the turbines are an eyesore and that their whirring causes headaches or disturbs sleep, there is little scientific evidence to suggest that the noise from wind farms causes any harm to humans beyond annoyance.

That’s the main message in a report released yesterday by the UI Environmental Health Sciences Research Center, Iowa Policy Project and Iowa Environmental Council. They based their conclusion on a review of two previous reviews of academic literature on wind turbines and human health.

Those reviews, conducted a few years ago, found no link between health outcomes and wind turbines, though they did find evidence of annoyance. The authors of the new report believe that risk perception plays a major role in perceived “annoyance” for neighbors of wind farms. Those that have a negative view of the turbines will be more likely to report negative health outcomes, whether or not they are actually exposed to harmful noises. Those that receive monetary compensation for the potential nearby nuisance will be less likely to report annoyance or health problems.

Nearly 37 percent of energy produced in energy is generated by wind power, according to the American Wind Energy Association. At over 8,400 megawatts, Iowa has the second highest wind power capacity in the nation. Ten wind power facilities have saved over 8.8 million metric tons of atmospheric carbon and provided over 7,000 jobs since the state started developing wind power infrastructure almost 20 years ago.

The authors of the report believe the benefits of the industry outweigh potential annoyances to neighbors.

“Given the evidence and confounding factors, and the well-documented negative health and environmental impacts of power produced with fossil fuels, we conclude that development of electricity fromwind is a benefit to the environment,” they wrote. “We conclude that wind energy should result in a net positive benefit to human health.”
