Wind Power Generators

Wind power generators are devices which are used in the generation of electrical current and are powered by the wind. Like in the days of yore, old fashioned windmills, today’s wind machines use blades to collect the kinetic energy made by wind. Windmills work because their blades slow down the speed of the wind. The wind flows over the airfoil-shaped blades causing lift, like found in the effect on airplane wings, making them turn. When the wind blows at a set speed (usually two miles an hour) the blades (connected to a drive shaft that turns an electric generator) produce electricity. More on how do wind turbines work
