HILLTOWNS– Examining the available data, a panel of experts found little to no evidence that wind turbines impact physical or psychological health. The state Department of Environmental Protection (DEP) and Department of Public Health (MDPH) convened the panel of physicians and scientists in an effort to address concerns the public has raised about possible health impacts caused by proximity to wind turbines.
The panel did not conduct its own tests or surveys, but studied existing data to draw their conclusions. A member of the panel, Associate Professor of Environmental Health, Wendy Heiger-Bernays, PhD, said the panel expended a great deal of time and energy on the work.
“This is a complex issue that the panel spent many months studying,” she said. “By reviewing the available data and information we believe that we have significantly added to the understanding of the potential for health effects from wind turbines.”
State DEP Commissioner Kenneth Kimmell offered thanks for the panel’s hard work. “It’s extremely important that we have the best science available to us as we make decisions on wind energy,” he said.
Among the panel’s key findings were:
There is no evidence for a set of health effects from exposure to wind turbines that could be characterized as “Wind Turbine Syndrome.”
Claims that infra sound from wind turbines directly impacts the vestibular system have not been demonstrated scientifically. Available evidence shows that the infrasound levels near wind turbines cannot impact the vestibular system.
The weight of the evidence suggests no association between noise from wind turbines and measures of psychological distress or mental health problems.
None of the limited epidemiological evidence reviewed suggests an association between noise from wind turbines and pain, stiffness, diabetes, high blood pressure, hearing impairment, cardiovascular disease and headache/migraine.
There is limited epidemiologic evidence suggesting an association between exposure to wind turbines and annoyance. There is insufficient epidemiologic evidence to determine whether there is an association between noise from wind turbines and annoyance independent from the effects of seeing a wind turbine and vice versa.
There is limited evidence from epidemiologic studies suggesting an association between noise from wind turbines and sleep disruption. In other words, it is possible that noise from some wind turbines can cause sleep disruption. Whether annoyance from wind turbines leads to sleep issues or stress has not been sufficiently quantified. While not based on evidence from wind turbines, there is evidence that sleep disruption can adversely affect mood, cognitive functioning, and overall sense of health and well-being.
Scientific evidence suggests that shadow flicker does not pose a risk for eliciting seizures as a result of photic stimulation. There is limited scientific evidence of an association between annoyance from prolonged shadow flicker (exceeding 30 minutes per day) and potential transitory cognitive and physical health effects.
Although the panel focused on existing information, it did receive extensive public comment, including from residents who live near wind turbines, according to DEP.
A public comment period on the panel’s findings will be open until Monday, March 19 at 5 p.m. Electronic comments can be submitted to: WindTurbineDocket.MassDEP@MassMail.State.MA.US, and written comments can be mailed to MassDEP, Wind Turbine Docket, One Winter Street, Fourth Floor, Boston, MA 02108.
Wind turbines have been proposed in Russell, Chester and Goshen, and at the New Hingham School in Chesterfield.
