Wind Fact Library
There's a lot of misleading information about wind energy available on the web. Most of it is based on hearsay and misinformation, readily rebuked by scientific evidence. It is our goal to provide you with accurate information regarding the effects of wind energy. Here we have collected a series of thoroughly conducted studies of wind power's impacts to health, safety, environment and economics. We hope to present you with a full understanding of how wind energy does - or more often doesn't - impact the world around us.
Various outlets have claimed that wind turbines cause adverse health effects. However, none of these claims stand up to the rigor of scientific evaluation. Studies that do meet the necessary scientific criteria have found that--at worst--wind turbines can cause irritation or annoyance to a small subset of the population. Neither annoyance nor irritation is a pathological condition. No credible scientific study has found that wind turbines cause negative health effects. This includes the Minnesota Department of Health, which does not recommend increasing setbacks from their current threshold.
On a home by home basis, it is difficult to predict the effect that any nearby development--including a wind farm--will have on property values. Because of this, studies of home prices near wind turbines tend to focus on property values across an entire community. These studies survey hundreds and thousands of homes, and have shown that construction of a wind farm does not affect average property values positively or negatively. Studies that claim that wind farms lower property values typically only focus on the handful of homes that happened to be negatively affected, ignoring the properties that were unaffected, or affected positively.
As a wind turbine's blade pass through the air they make an audible swooshing noise. From safe setback distances--as established by the Minnesota Public Utilities Commission--however, these sounds do not even approach harmful levels of noise. Likewise, the low frequency noise emitted by wind turbines is safe, and is not different than any other source of noise.
One item that is often overlooked in discussion of the subsidies that wind energy developments receive are the subsidies that other forms of energy production receive. Coal, for example, receives three times the subsidies that wind energy does. Wind energy is not a silver bullet for our energy needs. Instead, it is just a piece of the larger energy production puzzle.
Modern electrical practices have virtually eliminated this problem and it poses no risk to livestock.
Best practices from the available research, and usage history in Europe and the United States, have determined shadow flicker not to be a health concern when appropriate setbacks are enforced.
