Wind energy uses the energy in the wind for practical purposes like generating electricity, charging batteries, pumping water, or grinding grain. Large, modern wind turbines operate together in wind farms to produce this electricity for the use of consumer utilities. Small turbines are used by homeowners and remote villages to help meet these energy needs. The basic concept behind wind energy is that the wind is the fuel source for wind energy. The United States has many areas with abundant winds, particularly in the Midwest and the Great Plains. Wind energy is considered a green power technology because it has only minor impacts on the environment. Wind energy plants are the only energy source that produces no air pollutants or greenhouse gases. However, any means of energy production impacts the environment in some way, and wind energy is no different. Global climate change resulting from the widespread burning of fossil fuels is the most important environmental problem of our time, and the most serious one that has ever confronted humanity. The application of wind energy is another of technologies ways of trying to find an alternative source of energy. Wind energy may not be as effective as the burning of fossil fuels, but with a little bit research and proper funding, we might get to the point where it can be. Stand-alone wind turbines are typically used for water pumping or communications. However, homeowners, farmers, and ranchers in windy areas can also use wind turbines as a way to cut their electric bills. The wind turbines are not unlike the wind catchers we use on porches etc. Small wind systems also have potential as distributed energy resources. Distributed energy resources refer to a variety of small, modular power-generating technologies that can be combined to improve the operation of the electricity delivery system.
