Wind turbines in farms not only capture renewable energy, but may also help crops grow more efficiently, a new study has found. Tall wind turbines disbursed throughout a field create air turbulence that may help plants by affecting variables such as temperature and carbon dioxide concentrations, said Professor Gene Takle of Iowa State University in the US.
Scientists installed research towers on a 200-turbine wind farm. The research towers collected data from 2010 to 2013 on wind speeds and directions, temperature, humidity, turbulence, gas content and precipitation. The project aimed to discover how the turbulence created when wind moves through the turbines affects conditions at ground level where crops grow.
The data show that the wind turbines have a measurable impact on several key variables that affect growing conditions.
