Wind energy or wind power is the extraction of kinetic energy from wind and the conversion of it into mechanical energy. Man has harnessed the power of the wind for many centuries. Wind is a type of solar energy. The sun heats the earth’s surface and the warmer air begins to rise. Cooler air flows into the area below the rising air causing wind. The Egyptians utilized the wind as early as 5000 B.C. by attaching sails to propel boats across the Nile River. For many years sailing ships on the open seas were powered by capturing the wind with sails. The Dutch adapted the windmill and used it to drain the lakes and the marshes of the Rhine River. Windmills are used in food production such as grinding grain. Since the early 1800s,

In some European countries over 20% of their electricity is produced from wind energy. The United States Department of Energy has set a modest goal of 20% renewable energy sources in the domestic energy portfolio by 2030. Sadly, due to economic issues less than 4% of electricity is generated from wind power. Wind Power is a clean renewable source of electricity that is now a viable option for electricity generation.
Wind power, unlike coal and natural gas, is a renewable source of energy. Coal plants are the largest producer of electricity in the United States, and natural gas is second. Coal and natural gas are fossil fuels that have been formed from organic matter such as plants and animals deposited millions of years ago. Fossil fuels are non-renewable. Fossil fuels are considered to be non-renewable because their quantities are limited and they cannot be replaced as fast as they are used. Fossil fuels are deposited deep in the earth and typically retrieved by mining or drilling. Electricity prices fluctuate unpredictably because of the use of fossil fuels. In contrast, wind energy is an inexhaustible source of power with huge untapped potential in The Great Plains and offshore. Unlike the use of fossil fuels, wind use is free. Prices of electricity would be more stable if the electricity generated from fossil fuel sources was replaced with electricity generated from wind farms. Utilizing wind energy does not deplete or destroy any natural
