Wind, with its immense energy potential, can prove to be a great source of power. Created by the uneven heating of the land masses by sun, wind power is a clean energy source. When the sun heats up the landmasses, the air above the land gets hot and rises up, allowing the air above it to take its place. Being an environment friendly source of energy, wind produces no pollutants and can be renewed.
Although it stores great power, wind energy is used less as a source of renewable energy. It is studied that the wind energy usage is confined to only 1% of the total world energy. However its usage is increasing every year. It has risen more than fivefold globally between 2000 and 2007. By 2010, the World Wind Energy Association expects 160GW of capacity to be installed worldwide, up from 73.9 GW at the end of 2006, implying an anticipated net growth rate of more than 21% per year.
The potential of wind power on land and near-shore is calculated to be around 72 terrawatts (TW), or over five times the world's current energy use in all forms (15 TW from all sources in 2005). This power of the wind needs to be tapped adequately. Over the years, the investments in wind power have risen owing to this fact.
