The wind is an essential element of human life. It is a sustainable energy source and it is the most inexpensive source of energy. It is also clean and safe unlike other forms of energy such as coal and nuclear power. Wind energy, used to create electricity, will not add pollutants into the air we breath. Millions of tons of carbon dioxide, nitrous oxides, and sulfur dioxide are released into the air every year by traditional power plants. Just one single 1-MW wind turbine will eliminate approximately 2,000 tons of carbon dioxide each year.
