How does wind energy work?

Wind energy is a type of solar energy that is generated by heat and circulation patterns in the Earth’s atmosphere.  This energy has been used for thousands of years in applications such as sailboats and windmills.  Today’s technology allows this energy to be harnessed in an even more practical way: to generate electricity.

As air flows past the rotor of a wind turbine, the rotor spins and drives the shaft of an electric generator.  This energy is then converted into a current that can be used to power appliances in your home.  Like solar power energy, if there is enough energy being produced, dependency on grid power becomes less of an issue.  In some cases and in some areas, enough wind power may be generated to replace the grid altogether and allow for a consumer to actually sell power to the grid.

What are the benefits of wind energy?

►  Wind is a renewable energy source.  It will not run out or be over-consumed.
►  Wind is a clean energy source that does not emit any harmful gases into the atmosphere.
►  Wind energy lowers electric utility bills by providing a much cheaper source of power.
►  Some areas offer tax incentives for wind power.
►  Energy that is not used is sold back into the utility grid for a credit.
