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.
Statement of Nancy Kalinowski, Vice President for System Operations Services, Air Traffic Organization of the FAA delivered this testimony before the House Armed Services Committee, Subcommittee on Readiness on the Impact of Wind Farms on Military Readiness. An excerpt of Ms. Kalinowski's testimony shown below explains the problem produced when the moving turbines interfere with radar. Her complete testimony can be accessed by clicking on the links at the bottom of the page.
Initial findings of this study indicated that the structure as described exceeds
obstruction standards and/or would have an adverse physical or electromagnetic
interference effect upon navigable airspace or air navigation facilities.
Pending resolution of the issues described below, the structure is presumed to
be a hazard to air navigation.
A necessary step in any attempt to understand the outlook for US
energy supply and demand

...some wind power facilities, such as
the Altamont Pass Wind Resource Area (APWRA) in eastern Alameda and Contra Costa Counties,
California, are causing severe environmental impacts to raptor populations due to bird kills from
collisions with turbines and electrocution on power lines.
The wind developer for Fairhaven Wind, two industrial-scale towers built near residences, has admitted that the sound survey conducted on October 15, 2012 was tainted due to one of the turbines, while still spinning, was not producing power. The developer insists human error was the cause but claims the no intent to artificially reduce the sound levels. The State of Massachusetts has ordered the results be discarded and for further studies to be conducted.
The Falmouth Massachusetts Health Department send this letter to the Massachusetts Department of Public Health requesting the Mass DPH immediately initiate a health assessment of the impacts of the operation of wind turbines in the town.
The Massachusetts Department of Environmental Protection announced that one of the two turbines sited in Falmouth exceeds noise levels permitted under State law. The letter from the MassDEP confirming the findings of a sound survey as well as the study report can be accessed by clicking on the links at the bottom of this page. An excerpt of the MassDEP letter is provided below.
In this easy to understand report, energy expert Glenn Schleede challenges assumptions and calculations made by wind proponents when citing the number of homes served by wind turbines.
