While the total capacity of wind farm energy production worldwide is 100,000 megawatts, the United States is leading in advancement and implementation of this technology and currently supplies over 18,300 megawatts of energy from it’s various small scale windfarms, including the Horse Hollow Wind Energy Center of Texas which is home to the world’s largest wind farm. The level of energy output produced from U.S. windfarms is currently adequate to service 5 million households with electricity. The American Wind Energy Association was formed in 1974 as the national trade association for the wind energy industry in the U.S., and is the leading body in providing wind energy research in an advisory capacity to the industry.
Among the distinct advantages of wind energy is that it’s conversion to usable electricity requires no chemical processes and therefore there are no bi-products are environmentally contaminating pollutants.
While there must be adequate and continual wind speeds to assure consistent energy output of turbine fields, obviously, wind is an unending source of energy. The equipment required, though, must take into consideration that consistent wind speeds are at elevated levels, therefore wind turbines must be very tall and require specialized equipment for their construction. Conversely, the extreme height required for adequate wind turbine generation makes it ideal for use in farmlands, where grazing animals, or crops can be planted around the turbine supports. Many wind farms are superimposed over existing farmland that supplies crop bi-products to the alternative liquid fuel industry. In addition, windfarms can be built off shore, therefore reducing even more of the landscape environmental impact.
As we consider the environmental impact of our energy choices and methods to convert and distribute forms of “clean” energy, it must also be understood that solar energy has an advantage over wind energy in that the wind turbines produce a considerable amount of noise. Also noted is the impact the wind turbine fields have on certain people who react negatively to the pulsation in the air waves created by the turbines and the visual impact to natural landscape with the implementation of wind turbine farms.
As solar and wind energy seem to be running neck in neck for the position of most widely used source of renewable alternative energy, it seems that the federal government is bracing to lend it’s support to the advancement of mass wind turbine farms. The economic impact of this development could mean renewed financial stature to many of the citizens of the United States as fabrication, construction and maintenance of the turbine fields will require a new industry of workers to support it.
