Study finds wind turbines not linked to health problems
Southwestern Ontario -- - Recently, Health Canada published findings from the Wind Turbine Noise and Health Study. Launched in 2012, in collaboration with Statistics Canada, this study explored the relationship between exposure to wind turbine noise and the health effects reported by, and measured in, people living near wind turbines.
In the effort of being more open and transparent, the findings are available on Health CanadaÂ’s website. The findings provide a more complete overall assessment of the potential impacts that exposure to wind turbines may have on health and well-being.
No evidence was found to support a link between exposure to wind turbine noise and any of the self-reported or measured health endpoints examined. However, the study did demonstrate a relationship between increasing levels of wind turbine noise and annoyance towards several features including noise, vibration, shadow flicker, and the aircraft warning lights on top of the turbines associated with wind turbines.
It is important to note that the findings from this study do not provide definitive answers on their own and must be considered in the context of a broader evidence base.
Health Canada has consulted the Wind Turbine Noise and Health Study Expert Committee on these findings. Detailed analysis and results will be shared with Canadians and the international scientific community over the next several months with updates provided on the Health Canada website.
Quick Facts
- The study was conducted in Southwestern Ontario and Prince Edward Island and included 1238 households out of a possible 1,570 households living at various distances from 399 separate wind turbines in 18 wind turbine developments.
-- This study is the first study related to wind turbine noise to implement the use of both self-reported and physically measured health endpoints.
-- Measured health-related indicators included hair cortisol as a biomarker of stress, blood pressure, resting heart rate and sleep.

California's solar energy gains go up in wildfire smoke
LOS ANGELES - Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.
Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California…
