A study has found that, taller turbines with shorter blades can reduce the impact of birds that are affected by wind turbines from collisions
The research analyzed data from 1,670 wind turbines and 86 bird observation routes across 36 states in the United States between 2008 to 2014.
The researchers stated that for one additional wind turbine, on average, leads to disappearance of about three breeding birds.
They also said that the turbine size is a critical determinant of the magnitude of this impact and the effect can be minimized by making the recommended adjustments. The research provides a more conservative estimate of birds affected by wind turbines and important implications for policies that can enhance the sustainability of wind energy.
