The term "Wind Power" describes the process by which wind energy is transformed into mechanical power or electricity. The wind has been used for centuries as a source for mechanical power and in the past 100 years, the wind has begun to be used for electricity. Over the past twenty-five years, scientists have refined wind power technology to become more efficient and profitable so that it can compete with other widely used energy resources. Energy is fundamental to our society it powers our homes, businesses, and industries; however, the process of generating electricity is our nation's single largest industrial source of air pollution. The costs, safety and environmental impacts continue to improve faster and faster and wind power is becoming one of the cheapest and "greenest" power resources available. Because wind power uses the wind, a naturally occurring phenomenon, it is considered a renewable resource that is found in abundance across the earth's surface. The use of renewable resources is extremely important because of their minimal impact on the environment. Energy is fundamental to our society it powers our homes, businesses, and industries. However, the process of generating electricity is our nation's single largest industrial source of air pollution (http://www.sierraclub.org/energy,2002). Besides the environmental effects of renewable resources reduce dependence on foreign fuels and precious domestic resources. The United States is an excellent location for wind power; many areas of the U.S have almost too much wind. One major problem with wind power is that power demands fluctuate radically, diurnally and annually, often not coinciding with fluctuations in wind production capacity. There are problems with wind power that continue to be resolved, and there is a lot of support for research and development domestically and abroad. As the prices for wind stations drop and the efficiency increases the popularity of wind power will increase in the future.
