Wind Energy, energy contained in the force of the winds blowing across the earth’s surface.
When harnessed, wind energy can be converted into mechanical energy for performing work such as pumping water, grinding grain, and milling lumber.
By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator, modern wind turbines convert wind energy, which turns the rotor, into electrical energy.
OUR MODEL IS WINDMILL
Windmill is a machine that converts wind into useful energy. This energy is derived from the force of wind acting on oblique blades or sails that radiate from a shaft. The turning shaft may be connected to machinery used to perform such work as milling grain, pumping water, or generating electricity. When the shaft is connected to a load, such as a pump, the device is typically called a windmill. When it is used to generate electricity, it is known as a wind turbine generator.
WHAT TYPE OF SOURCE IS IT?
It is renewable,because you can’t run out of it.wind is every were.
The Sun's energy, acting on the oceans and atmosphere, produces winds that for centuries have turned windmills and driven sailing ships (see Wind Energy).
Modern windmills are strong, light, weather-resistant, aerodynamically designed machines that produce electricity when attached to generators.
WHAT IS THE IMPACT OF ENERGY ON NATURAL RESOURCES
Although wind energy is a relatively clean means of generating electricity, there are associated impacts.
The potential of an array of turbines to alter the visual quality of the landscape, especially when located in a scenic area.
In addition to aesthetic concerns, noise associated with spinning wind turbine rotors has generated complaints from the public, although recent technology has done much to address this issue.
