The Fundamentals of Wind Energy

Hearing the term "wind energy" probably conjures up images of ancient, wooden windmills. The modern version of the windmill is the wind turbine, which is a mechanical device found in wind farms that can produce electricity in mass quantities. Wind energy is just one of the many types of renewable energy now used to reduce our dependence on finite energy sources.

Wind Turbines as a Source of Electricity

The wind turbines found on wind farms typically feature three blades that measure up to 130 feet in length and rest atop steel towers that can be up to 300 feet high. The blades are pointed toward the wind and rotate at speeds up to 200 mph. A large commercial turbine is capable of generating up to five million watts of electricity.

The Future of Wind Energy

Our dependence on wind energy is expected to increase in the coming years. A U.S. Department of Energy study has called for wind energy to provide 20 percent of the United States' total energy needs by the year 2030. As wind energy technology continues to improve, you can expect to see more wind farms built in different parts of the nation.
