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...

Wind turbines not paying off McGUFFEY — When the wind turbines were installed at the Upper Scioto Valley Schools, it was expected the power generated by the system would save the district hundreds of thousands of dollars on its electric bills. To complete the project, build the green lab and make other improvements to the school facility, the district borrowed $860,000 through House Bill 264, which allows districts to borrow against future energy savings. The wind turbines were expected to produce 33,333 kilowatt hours of energy and the district would save between $900 and $1,500 per month. After more than a year of operation, both figures are far short of the predictions, said Steve Canfield, the district’s maintenance director and David Schoonmaker, electrical engineer with H.T. Burnsdorf. Canfield estimated the cost of a kilowatt is 8.7 cents from AEP and the cost from the wind-generated power is less than a penny less than that rate. The cost of solar energy is costing USV 7.9 cent...
