Wind turbine wake effects

Wake_effect_horns_rev.jpg_thumb The image shows clouds forming in the wakes of the front row of wind turbines of the Horns Rev wind farm off the coast of Denmark. The downstream wind turbines lose 20% or 30% of their power, and sometimes even more, relative to the front row. The spacing of the turbines is 7 rotor diameters.
