Noise Radiation from Wind Turbines Installed Near Homes: Effects on Health
January, 2007
by Barbara J. Frey and Peter J. Hadden
Wind turbines are large industrial structures that create obtrusive environmental noise pollution when built too close to dwellings. This annotated review of evidence and research by experts considers the impact of industrial-scale wind turbines suffered by those living nearby. First, the paper includes the comments by some of the families affected by wind turbines, as well as coverage in news media internationally. The experiences described put a human face to the science of acoustics.
Second, the paper reviews research articles within the field of acoustics concerning the acoustic properties of wind turbines and noise. The acoustic characteristics of wind turbines are complex and in combination produce acoustic radiation. Next, the paper reviews the health effects that may result from the acoustic radiation caused by wind turbines, as well as the health effects from noise, because the symptoms parallel one another. Primarily, the consequent health response includes sleep deprivation and the problems that ensue as a result. In addition, this paper reviews articles that report research about the body's response not only to the audible noise, but also to the inaudible components of noise that adversely affect the body's physiology. Research points to a causal link between unwanted sound and sleep deprivation and stress, i.e., whole body physiologic responses.
These injuries are considered in the context of Human Rights, where it is contended that the environmental noise pollution destroys a person's effective enjoyment of right to respect for home and private life, a violation of Article 8 of the European Court of Human Rights Act. Furthermore, the paper considers the consequent devaluation of a dwelling as a measure of part of the damage that arises when wind turbines are sited too close to a dwelling, causing acoustic radiation and consequent adverse health responses.
The review concludes that a safe buffer zone of at least 2km should exist between family dwellings and industrial wind turbines of up to 2MW installed capacity, with greater separation for a wind turbine greater than 2MW installed capacity.

UK Energy Policy: The Small Business Perspective & The Impact on the Rural Economy
January, 2006
by Candida Whitmill for and on behalf of The Small Business Council
This report surveys the intense debate now taking place as to why
the chosen strategy is not achieving its objectives. We believe that a
principal factor is to be found in the increasingly controversial renewable
energy policy, which is widely criticised for its lack of balance and its
over-emphasis on onshore wind at the expense of other technologies.
Written in 2000 by the Country Guardian, the UK's leading 'action group', this report addresses comprehensively wind issues in the UK. As one of the first papers of its kind, it is generally viewed as a 'classic' and 'required reading' for those interested in becoming thoroughly familiar with the diverse impacts of industrial wind.
