The so-called wind turbine syndrome has received quite a bit of attention of late. For example, on How Stuff Works:
Until recently, there were three main issues regarding the possible downsides of wind power: bird and bat deaths, cost, and disrupting the appearance of natural landscapes. But a new objection to wind power has popped up in the past few years, resting on the research of a few scientists. The latest argument states that wind power endangers the health of people who live near windmills. Some people call this theory "wind-turbine syndrome." Although the extent of the phenomenon is unknown, there does seem to be something to it.
The explanation includes harm from infrasound and noise-related sleep loss, as discussed here:
It's understood that some people who live in close proximity to wind turbines experience sleep disturbances, headaches and concentration problems. These symptoms and others could be explained as the effects of infrasound as well as constant humming and vibrations.
Others argue that there is no evidence of any harm, for example:
A study, Wind Turbine Sound and Health Effects, was conducted in 2009 by a panel of medical professionals from the US, Canada, Denmark, and UK. The study concluded, “There is no evidence that the audible or sub-audible sounds [including infrasound] emitted by wind turbines have any direct adverse physiological effects.”
A new study published by the Bavarian Environment Agency in Germany in 2012 has concluded similarly to the previous. The study – ‘Wind turbines: does infrasound affect health?’ concludes that wind turbines do not generate infrasound at a level that would damage human health. Wind energy structures generate infrasound that is far below normal human hearing and perception; this is why it does not cause any damage to people.
Is there any merit to the complaint that wind turbines harm health?
