In addition, project developers are required to collect data through monitoring efforts at existing and proposed wind energy sites. Careful site selection is needed to minimize fatalities and in some cases additional research may be needed to address bird and bat impact issues. While structures such as smokestacks, lighthouses, tall buildings, and radio and television towers have also been associated with bird and bat kills, bird and bat mortality is a serious concern for the wind industry.
Unlike most other generation technologies, wind turbines do not use combustion to generate electricity, and hence don't produce air emissions.eltheftitobo.gq
The only potentially toxic or hazardous materials are relatively small amounts of lubricating oils and hydraulic and insulating fluids. Therefore, contamination of surface or ground water or soils is highly unlikely. The primary health and safety considerations are related to blade movement and the presence of industrial equipment in areas potentially accessible to the public.
An additional concern associated with wind turbines is potential interference with radar and telecommunication facilities. And like all electrical generating facilities, wind generators produce electric and magnetic fields.
Wind Energy Basics. Environmental Concerns.
Wind Energy Photos. Wind Energy Maps. Wind Energy Links. Noise Like all mechanical systems, wind turbines produce some noise when they operate. Visual Impacts Because they must generally be sited in exposed places, wind turbines are often highly visible; however, being visible is not necessarily the same as being intrusive.

Other Concerns Unlike most other generation technologies, wind turbines do not use combustion to generate electricity, and hence don't produce air emissions. Opponents of wind argue that wind requires dedicated back up power, such that all the gains that are made are nullified by the wrongful notion that each MW of wind requires an equal MW of backup gas or some other polluting source of power.
This overly simplistic argument could not be further from the truth. While it is true that wind contributes to system variability as do most things that are connected with the grid — our dishwashers, elevators, and industrial pumps all run when people choose, not at the whim of system operators , wind is in fact adding some variability to an already variable grid.
In short, system operators are already used to dealing with variability; in the same way we can predict how demand will increase in the morning and decrease at night, we are also getting really good at predicting changes in output from renewable resources such as wind.

In fact, when added to the grid, wind energy will reduce fuel consumption and GHG emissions alike. Unlike most other sources of electricity, wind energy does not require water to operate.

Because of this, wind can be deployed in arid regions and areas with scarce water supply and strict water consumption and use regulations think California. Wind energy is actually net positive with respect to water; because wind is emissions free, wind helps to combat climate change, which poses a significant threat to aquifers due to changes in precipitation patterns and temperature.

Wind energy and wildlife are effective dance partners. A recent report from Environment Canada found that avian mortality from wind turbines was extremely low relative to other sources of mortality windows, cats, climate change, etc. Even in areas where wind energy is facing challenges, such as with respect to certain species of bats, the wind industry steps up and tackles the issue head on.
