Ontario’s chief medical officer of health reviewed 40 years of science from 1970 to 2010, and concluded the evidence "does not demonstrate a direct causal link between wind turbines noise and adverse health effects."
The Australian government conducted a review of the scientific literature on wind and health and concluded that, at the time of writing, "there was no published scientific evidence to positively link wind turbines with adverse health effects."
A landmark study in Scientific American (Nov. 2009) examined wind power’s cost. The authors concluded that, by 2020, "wind power is expected to be the least costly of all options."
In short, the science suggests wind energy is both safe and affordable.
