How do wind turbines effect the community?
We know that, wind turbines do not release emissions that can pollute the air or water and they do not require water for cooling. It may also reduce the amount of electricity generation from fossil fuels which results in lower total air pollution and carbon dioxide emissions.
"Sound' and 'visual impact' are the two main public health and community concerns associated with operating wind turbines. Most of the sound generated by wind turbines is 'aerodynamic' which caused by the movement of turbine blades through air. There is also mechanical sound generated by the turbine itself. Overall sound levels depend on turbine design & wind speed.
Additionally, technological advances such as "minimizing blade surface imperfections" and "sound absorbent materials" can reduce wind turbine noise.
When it comes to aesthetics, wind turbines can elicit strong reactions. Visual impacts are the focus of this discussion of aesthetic impacts, but noise is considered to the extent that it is related to the overall character of a particular landscape.
