This letter was sent to Jim Lepinski of the Wisconsin Public Service Commission. The letter captures the anger and frustration of people living within a quarter-mile of industrial turbines.
This WV Supreme Court decision decided in June 2007 provides a concise argument pertaining to nuisance issues (noise, flicker, strobing) and hazards as they relate to wind energy facilities built near residences. The background of the case and the court's conclusion are listed below. The full decision, including the discussion of nuisance issues and hazards, can be downloaded by clicking on the link. The court references substantial case law to support its decision.
This chapter provides guidelines for the marking and lighting of wind turbine farms. For the purposes of this advisory circular, wind turbine farms are defined as a wind turbine development that contains more than three (3) turbines of heights over 200 feet above ground level. The recommended marking and lighting of these structures is intended to provide day and night conspicuity and to assist pilots in identifying and avoiding these obstacles.
Two industrial wind turbine farms are proposed by parent UPC Wind Partners for the town of Cohocton, NY and will permanently alter the town. The large blades on MW scale turbines can at certain times produce moving shadows on the landscape or create distracting flicker on the scenery. To capture the wind these turbines are to be installed on hilltops around the town and thus have significant potential to create a shadow flicker nuisance at great distances from the turbines. All environmental effects of projects require consideration and possible mitigation. Siting selection is important since wind turbines are a permanent installation and may significantly impair resident’s enjoyment of neighboring lands or even personal health.
As interest in wind energy spreads throughout the Commonwealth, it becomes clear that there is a need within the cities and towns of Massachusetts for suitable zoning by-laws that accommodate wind projects. To help address this need, the Massachusetts Division of Energy Resources and Executive Office of Environmental Affairs developed this Model Amendment to a Zoning Ordinance or By-Law to assist cities and towns in establishing reasonable standards for wind power development. The by-law is developed as a model and not intended for adoption without review by municipal counsel:

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.

...I want people to be well aware of the negative side of these giant windmills before allowing them to be built in your neighborhoods.
Shadow Flicker Shadow flicker is caused by the sun rising or setting behind the rotating blades of a turbine. The shadow created by the rotating blades can cause alternating light and dark shadows to be cast on roads or nearby premises, including the windows of residences, resulting in distraction and annoyance to the residents. A related phenomenon, strobe effect, is caused by the chopping of sunlight behind moving blades, similar to the effect of the setting sun behind trees when driving along a roadway in the winter. Both of these phenomena are factors in the visual impact of a wind turbine project, and some argue that they are a threat to health and safety. They could also be considered a nuisance to nearby property owners.
3.8 Health & Safety Affected Environment, Environmental Impacts and Mitigation Measures "A number of comments submitted for the scoping process for the Desert Claim project EIS addressed concerns relating to potential health and safety issues. Specific topics indicated in these comments included certain possible hazards that are uniquely associated with wind turbines, such as blade throw and ice throw; health and safety issues associated with electrical and magnetic fields; more common hazards such as fire; and the incidence and impacts of shadow flicker, another phenomenon specific to wind turbines. Section 3.8 addresses these wide-ranging health and safety topics that have been identified as concerns for the environmental review. "
Lincoln Township in Wisconsin sent a survey to its residents to help assess the impacts of 22 turbines installed by Wisconsin Public Service Corporation (WPSC) and Madison Gas and Electric (MG&E), which went online in June 1999. A summary of the survey comments received is provided in the attached document. After the wind turbines went online, the Lincoln Township Board of Supervisors approved a moratorium on new turbine construction.
ADVISORY CIRCULAR: AC 70/7460-1K Obstruction Marking and Lighting-- This change amends the Federal Aviation Administration’s (FAA) standards for marking and lighting structures to promote aviation safety. This change is effective August 1, 2000.....A sponsor proposing any type of construction or alteration of a structure that may affect the National Airspace System (NAS) is required under the provisions of 14 Code of Federal Regulations (14 CFR part 77) to notify the FAA by completing the Notice of Proposed Construction or Alteration form (FAA Form 7460-1). The form should be sent to the FAA Regional Air Traffic Division office having jurisdiction over the area where the planned construction or alteration would be located.
