Extensive testing shows that a windfarm 500 metres away is less noisy than a car traveling at 40 miles an hour half a block away. A wind farm 2 km away will not produce enough sound to be heard above the normal background noise of a rural nighttime or a quiet bedroom.

Fact: Concerns about health impacts from wind turbine sound, infrasound and flickering light have been extensively studied around the world and found to have no significant impact on human health.

Fact: Windmills can potentially have impacts on birds through collisions and habitat disruption. However, the impact is very small, and dramatically less than that of urban sprawl, buildings, house cats or climate change. For example, one study notes that for every 10,000 birds killed by human activities including fatalities by collisions with man made structures, less than one death is caused by a wind turbine. For every 1 bird death caused by a wind turbine, 1,000 to 2,000 bird deaths are caused by cats. Even the National Audubon Society strongly supports wind power as a clean alternative energy source that reduces the threat of global warming.

Fact: There is no evidence that the presence of a commercial windfarm within sight of a property reduces its value. Some studies even show the sight of windmills raises property values. The U.S. National Association of Realtors writes “…wind farms appear to have a minimal or at most transitory impact on real estate.”

Fact: Beauty is in the eye of beholder, and no two people agree completely on what is beautiful. However, research and anecdotal evidence indicate that wind developments do not negatively influence the viewscape. On the contrary, they have often been found to be a positive influence on tourism.
