Wind Farms Cause More Environmental Impact Than

Average land elevation in USA is 610m, and the blades of a wind turbine typically extend from 50m above ground to 150m above ground. Axis of a wind turbine then typically is 710m above ground. Between the axis and a height of say 2km, the average air density(@300K) is about 0.96kg/m3. So, our average citizen on the 177m square of land is
