Wind power is one of the energy resources that have been in use for a very long time. It was used in powering sailing ships, which made it possible for explorers to sail around their trade routes in distant lands. A single windmill can power crop irrigation and cover family energy needs such as water pumping and electric lights. However, in the present time there are several windmills that are used to generate required energy mostly for industrial uses. Many of the wind turbines can capture much power all at once before feeding it to the power grid. This is commonly known as wind farms and has been in use for many years all around the world. It is only the United States that is going slow in terms of accepting this alternative energy source.
Wind power is renewable, and it does not cause any air pollution. Advancement in technologies has brought down the cost of setting up wind power plants. However, wind energy only be used in areas with high winds, which means that it can not be used as a source to extract energy anywhere on Earth. Wind turbines sometimes create noise disturbance and can not be used near residential areas. These disadvantages have made the use of wind energy limited to particular regions only.
