wind turbines are bird processors...

what is most annoying, is the low frequency vibration the turbine resonates through the ground...people in Oregon have decided health issues due to this vibration. Not sure if your soil type will transmit this or not...

you may not want a bunch of flashing lights either....

this makes no sense...
EGNX has just erected 2 on the airport
wind turbines also create a doppler effect, which disrupts the airbourne radar and airport radar systems. Currently, I believe they are trying to coat the blades with the military grade radar absorbing paints, but I am not sure if this is successful or not.

FAA testimony....

"The clutter that is created by wind turbines can result in a complete loss of primary radar detection above a wind farm. When that clutter occurs, it appears at all altitudes, so simply directing the aircraft to a different altitude does not solve the problem. Similarly, on the Next Generation Weather Radar (NEXRAD), wind farm activity looks remarkably like storm activity, thus complicating the communication of precise weather information by controllers to pilots. (Wind turbine impacts on NEXRAD, which are owned and operated by the National Oceanic and Atomospheric Administration, are not currently considered in FAA’s evaluation process.) Existing FAA radars have limited capability to filter out clutter. The radar can be modified by increasing the sensitivity to reduce clutter from the wind turbines, but in doing so, what the radar can see is also reduced, to the point where actual aircraft targets can drop off. Consequently, there are real and significant issues that must be evaluated by the government prior to the approval of wind turbines."

Good Luck!
