A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is
used to produce electricity, the device may be called a wind generator or wind charger. Developed for over a millennium,
today's wind turbines are manufactured in a range of vertical and horizontal axis types. The smallest turbines are used for
applications such as battery charging or auxiliary power on sailing boats; while large grid-connected arrays of turbines are
becoming an increasingly large source of commercial electric power.
Today's wind turbines are lighter, more robust and more efficient . If you live in an area with suitable
conditions, wind energy may be fight for you as alternative or adjunct to other renewable energy
