While a single wind-turbine does not affect the global atmosphere, the installation of a large number of such devices will interfere with the atmospheric circulation and diminish the extraction efficiency on the large scale, since any extraction of momentum will act in competition with natural wind-power energy dissipation by turbulence in the boundary layer.
