There are negative issues relating to wind turbines and their effect on the environment.
- Opponents point out the danger to birds and bats, which can be killed or injured by the rotating turbine blades.
- There are those who feel that there are distracting, distressing noise levels associated with the turbine operation.
- The aesthetics of wind turbine farms meets with mixed reviews, accepted and enjoyed by some, deeply opposed by others.
The negative environmental effects of wind power generation, however, must also be considered in the light of positive effects, such as greatly diminished pollution of the air and zero carbon emissions.
