While harnessing more energy from the wind could help satisfy growing demands for electricity and reduce emissions of global-warming gases, turbulence from proposed wind farms could adversely affect the growth of crops in the surrounding countryside.

"If wind is to be a major player in global electrical production, however, we have to think in terms of even larger scales- of say, thousands of turbines per wind farm" -- Somnath Baidya Roy, Professor, Atmospheric sciences, University of Illinois
