Directly from the Nordex, the Wind Turbine Manufacturer

The following information is from the proposed wind turbine manufacturer's website. www.nordex-online.com. It concerns the manufacturer's recommended minimum distance from homes, due to noise and shadow flicker concerns, and recommendations for wind farm employees in terms of the distance they should remain from the turbines.

Micrositing
Choosing the type of wind turbine (WTG) and its exact position are very important parts of the planning work of a wind park. This process is called micrositing.
During micrositing many aspects have to be regarded:
wind conditions (statistical data concerning wind speed and wind direction)
building requirements (e.g. distances to residences)
ownership structure of the area
accessibility (existing roads)
influence of the WTG on the environment (e.g. shadow flickering, noise emission)
distances between the individual turbines in a park
The knowledge of the wind conditions is very important for the decision about the development of a wind park. It is always the best to have measured data of the planned site for a period of at least two years. But this is not always possible. In case of a shorter measurement period wind consultants can find out the conditions by an interpolation of long-term measurements of near-by weather-stations.
Based on the information about the wind conditions it is possible to choose the type of turbine and the park layout which provides the highest energy production while keeping the external requirements. Based on a realistic forecast of the energy production it is possible to decide whether to invest in wind energy or not.
It is important to keep a distance to the next residences in order to not disturb the inhabitants by noise emission and shadow flickering of the turbine. Normally there have to be at least 500m (1,640ft) between the wind turbine and the next residence.

Stay and Traffic by the Turbine
Do not stay within a radius of 400m (1,300ft) from the turbine unless It is necessary. If you have to inspect an operating turbine from the ground do not stay under the rotor plane but deserve the rotor from the front. Make sure that children do not stay by or play nearby the turbine. If necessary fence the foundation.

Safe setbacks: How far should wind turbines be from homes?

Safe setbacks: How far should wind turbines be from homes? Let's start with what one manufacturer considers to be safe for its workers. The safety regulations for the Vestas V90, with a 300-ft rotor span and a total height of 410 feet, tell operators and technicians to stay 1,300 feet from an operating turbine -- over 3 times its total height -- unless absolutely necessary. That already is a much greater distance than many regulations currently require as a minimum distance between wind turbines and homes, and it is concerned only with safety, not with noise, shadow flicker, or visual intrusion. In February 2008, a 10-year-old Vestas turbine with a total height of less than 200 feet broke apart in a storm. Large pieces of the blades flew as far as 500 meters (1,640 feet) -- more than 8 times its total height. The Fuhrländer turbine planned for Barrington, R.I., is 328 feet tall with a rotor diameter of 77 meters, or just over 250 feet (sweeping more than an acre of vertical air spa...

Are Wind Farms Helping or Killing Us?

  From the UK's Daily Mail By James Delingpole A wind turbine in Bedfordshire; while some people have welcomed the wind farms, others say they have a detrimental effect on their health Read more: http://www.dailymail.co.uk/home/moslive/article-2199284/Wind-farms-Are-wind-farms-saving-killing-A-provocative-investigation-claims-thousands-people-falling-sick-live-near-them.html#ixzz260mqadne "It was Uplawmoor’s tranquility and wild beauty that drew civil servant Aileen Jackson to settle there 28 years ago. She’d had enough of life in the big city. Now she wanted somewhere quiet and rural to start a family, keep her horses, and enjoy the magnificent views down the valley and out to sea to the western Scottish isles of Arran and Ailsa Craig. Then, two years ago, she says, it all turned sour. A neighbour with whom she and her family had been friends decided to take advantage of the massive public subsidies for ‘renewable’ energy. He put up a 64ft-high wind ...

Wind Turbines & Noise

Who should influence the wind turbine noise debate By Stephen E Ambrose Stephen Ambrose is a Board Certified Member of the Institute of Noise Control Engineers (INCE) with over 35 years’ experience investigating man-made problems in environmental sound and industrial noise control. I am respectfully writing in response to the letter by Gordon L. Deane; “Misinformation has undue influence in turbine debate” of February 2, 2012 for the SouthCoastToday.com. I have a question; how did he get himself in such an awkward position? His engineers should have foreseen and advised that there would be an adverse public response to wind turbine noise. There are published documents that would have clearly shown neighbors’ seeking relief with appeals for legal action. My profession as INCE member requires that I honor and obey “Canons of Ethics”. 1) Hold paramount the safety, health and welfare of the public. 2) Provide services only in areas of competence. 3...
