Expert Panel Finds No Ill Effects From Wind Turbines
The 164-page report was released on Tuesday and was made available to the public because of "the high level of interest in the panel's findings," according to statement from the MassDEP. Three public meetings on the report will be held in February as part of a 60-day comment period.
The report's findings are of considerable interest to residents of Western Massachusetts, which the state has identified as having prime sites for wind turbines. Gov. Deval Patrick as part of his energy plans has set a goal of generating 2,000 megawatts of electricty through wind power by 2020.

The panel, charged with researching the effect in collaboration with the state Department of Public Health, included "physicians and scientists with broad expertise in areas including acoustical noise/infrasound, public health, sleep disturbance, mechanical engineering, epidemiology, and neuroscience."
According to MassDEP, among the findings:
► Claims that infrasound 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.
► 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.
