The Canadian Wind Energy Association welcomes recent research by Health Canada , a summary of which, concludes that there is no evidence of a causal relationship between exposure to wind turbine noise and self-reported medical illnesses and health conditions.
Specifically, the Health Canada study finds:
No evidence to support a link between exposure to wind turbine noise and any of the self-reported illnesses and chronic conditions
No association between multiple measures of stress and exposure to wind turbine noise
No association between wind turbine noise and self-reported or measured sleep quality
No association between wind turbine noise and any significant changes in reported quality of life, or with overall quality of life, and satisfaction with health.
The study did find a correlation, but not a causal relationship, between increasing levels of wind turbine noise and annoyance. The Health Canada summary identified a number of other factors that may contribute to annoyance levels, including economic benefit, visual appearance and noise sensitivity.
“Based on the summary, the Health Canada study is an important new addition to scientific research on wind turbines and human health. We look forward to reviewing the results of the Health Canada study in more detail and will continue to monitor the scientific literature in this area,” says Hornung. “The balance of scientific evidence to date continues to show that properly sited wind turbines are not harmful to human health and that wind energy remains one of the safest and environmentally friendly forms of electricity generation.”
