Wind Energy

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And wind has long served as a power source to humans.

Benefits

It’s a clean fuel source. Wind energy doesn’t pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don’t produce atmospheric emissions that cause acid rain or greenhouse gases.

It’s sustainable. Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth’s surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.

Wind power is cost-effective. It is one of the lowest-priced renewable energy technologies available today, costing between four and six cents per kilowatt-hour, depending upon the wind resource and the particular project’s financing.

Advantages

1)  Wind Energy is an inexhaustible source of energy and is virtually a limitless resource.
2) Energy is generated without polluting environment.
3)  This source of energy has tremendous potential to generate energy on large scale.
4)  Like solar energy and hydropower, wind power taps a natural physical resource.
5)  Windmill generators don’t emit any emissions that can lead to acid rain or greenhouse effect.
6)  Wind Energy can be used directly as mechanical energy.
7)  In remote areas, wind turbines can be used as great resource to generate energy.
8)  In combination with Solar Energy they can be used to provide reliable as well as steady supply of electricity.
9) Land around wind turbines can be used for other uses, e.g. Farming.
