In some parts of the world, people have raised questions about the sustainability of wind energy. People who raise these questions usually agree that they are bothered by the effect of pollutants into the environment and also by the effect of wind farms on natural habitat. Some argue that it is not economically sustainable. They add that wind energy does not pay for itself and that it can only be sustained over a short term. However, others argue that all indications are that the effects of wind energy on the environment will be far greater than those that have been previously thought.
There are many arguments that can be brought forward in defense of the sustainability of wind energy. First of all, they say that it cannot be sustainably supported over a long term. Proponents of the argument suggest that wind turbines are too inefficient and therefore cannot be seriously expected to last. They also point out that when the Wind Mills was first there to generate commercial electricity, they were used to power more industrial machinery than ever before. The reason being that it was necessary for these industries to keep their costs down because of the competition with cheap energy sources coming from Asia. Many other industries also pointed out that it is difficult to build the required infrastructure of wind energy plants on an economical scale.
As regards another issue, it is argued that the use of clean energy sources like wind power has always had a part to play in keeping the environment clean. It is argued that if all efforts are not made to preserve and protect our ecosystems, then the damage that will be caused to them can be devastating. This can be seen to be a very big problem in the future, as many developing countries whose economies rely heavily on fossil fuels, will have to find a way of maintaining the sustainability of their energy supplies. There are many other environmental issues that can be linked to the sustainability of wind power, the main one being the reduction in greenhouse gas emissions due to the efficient use of wind power. Therefore, it can be seen as a clean energy alternative that has many benefits in terms of its cost savings and contribution to reducing global warming.
