Wind energy is praised for being a renewable, nonpolluting source of electricity, but it can also produce intermittent streams of energy, and wind-generating equipment may be costly and troublesome to repair and maintain. One of the primary benefits of wind energy is that, unlike coal, oil and other fossil fuels, it does not emit toxic byproducts into the air and water.
Wind energy must often be supplemented with other forms of electricity because it does not produce enough energy to meet consumer base demands. In addition to providing clean energy, wind turbines are quite space efficient and can be sited in a variety of locations, including urban centers, brownfields and even offshore. However, turbines do produce some noise, which can be problematic for neighboring communities.
