  • TOPIC; ENERGY SOURCE

  • SUBTOPIC; WIND ENERGY


What is the energy source

WHAT IS THE ENERGY SOURCE.

  • 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

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

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

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.
