'Green on Green: Public Perceptions of Wind Power in Scotland and Ireland

Green_on_green_jepm_1__thumb The wind energy debate represents a new kind of environmental controversy which divides environmentalists of different persuasions who attach contrasting priority to global and local concerns. Case studies of public attitudes towards existing and proposed windfarm developments in Scotland and Ireland are used to test three counter-intuitive hypotheses derived from previous attitudinal research. Editor's Note: This study was conducted in collaboration with the Macaulay Institute, Aberdeen. The Institute's commercial arm, Macaulay Enterprises, acts as a consultant for the renewables industry, and is linked to the Scottish Renewables Forum and the British Wind Energy Association. The pro-wind pre-disposition of the authors is evident and should not be ignored when evaluating survey results. Survey respondents generally expressed support of wind energy based on the belief that it was a solution for global warming. Given wind energy's limited effectiveness in reducing greenhouse gases based on today’s studies, we question how survey participants might respond if contacted again. The report also comments that communities selected had no organized opposition to the wind facilities. Today, throughout England, Wales and Scotland, organized opposition is the norm, not the exception.

noise is an Issue in Searsburg

I have endured the industrial droning for close to ten years, with the added arrhythmic clunk of the gears from the turning mechanisms. This is described as a “barely noticeable” sound. I beg to differ. Due to this industrial noise pollution, I can no longer bring pets to the property, because the droning disorients them in the woods. The impact to the wildlife must be even more severe, despite the claims of the power company’s ‘consultants’. Regardless, my family’s enjoyment of the quiet of the woods is severely diminished.

Proposed criteria in residential communities for low-frequency noise emissions from industrial sources

Hessler_c-wt_limits_for_rural_areas_thumb Excessive low-frequency noise from open-cycle combustion turbine power plants has been recognized as a serious noise and vibration problem since the early 1970s. Yet, the problem still occurs, mainly because siting and specifying agencies are largely uninformed about the problem and because there are no standardized noise criteria in the U.S. to consult for guidance in avoiding low-frequency noise problems. Detailed sound pressure level measurements from five low-frequency problem sites are analyzed for support of a proposed criterion. The data are compared to noise and vibration thresholds. In addition, a small sampling of responses from residents to varied levels of low-frequency noise immissions is presented. This paper proposes a “C” weighted overall sound level criterion. The proposed criterion should be applicable to most industrial sources of steady low-frequency noise in addition to combustion turbines.

"The noise was incredible."

This is a letter written by Paula Stahl of St. George, West Virginia, about her experiences living in the neighborhood of the 66 MW Mountaineer Wind Energy Center. Formerly known as the Backbone Mountain Wind Farm, the 4,400-acre site has 44 turbines, 1.5 MW each, stretched along miles of ridgeline in Tucker and Preston counties. Ms. Stahl submitted the letter to the Berkshire Eagle and North Adams Transcript, neither of which has printed it.
