Why Is Wind a Renewable Resource?

The power of wind is harnessed by man to generate electricity. Wind power is gaining worldwide recognition as an alternative energy source.

Production

Wind power is generated when wind is used to rotate two to three propeller like blades around a rotor. This action spins a generator. This unit is known as a wind turbine. In a large scale setup, wind turbines are organized in groups which produce electricity in a wind farm.

Renewable Nature

Wind power uses wind energy which is generated by the heating and cooling of the earth each day by the sun. The sun is an inexhaustible source which makes wind power renewable.

Benefits

Wind is provided by Mother Nature. It is an eco-friendly alternative because it creates little to no pollution during power generation. In addition, wind power also creates new job opportunities as wind farms hire people to set up and maintain the turbines.

Downsides

One of the major disadvantages of wind power is the constancy factor. The strength of the wind is variable--from non-existent (when there is no wind blowing) to maximum force (when there is a storm). Wind turbines can also be quite noisy and hamper the visual impact of a landscape.

Potential

The potential for wind power is enormous because of its inexhaustible nature. However, it is largely untapped as of 2009. Some countries, such as Denmark, use wind power to a great extent (contributing up to 20 percent of its energy needs).
