Being a renewable source of energy, it can be replenished again and again, without the fear of it getting it getting over. It is believed that there is abundant wind energy present in the atmosphere, more than that is required by the whole world. The potential of wind power on land and near-shore is close to 72 terawatts (TW). This is calculated to be over five times the world's current energy use in all forms.

The wind energy sector is growing rapidly with the growth registering at the pace of 28% a year for the past five years. If this rate continues, wind capacity will double about every three or four years. One of the major technologies of wind energy in use today is the wind turbines. The wind turbines work by transforming the kinetic energy in the wind into mechanical power, which is the n used generate electricity.

Wind energy is one of the cheapest and also the cleanest source of energy. The environmentalist’s preferred choice of alternate energy as it does not produce any harmful gases and does not contribute to greenhouse effect. Owing to its great advantages and the wind power investment opportunities, the wind sector is attracting a great deal of investor attention. ]]> Grimaud http://www.aboutmyplanet.com/community/solar-wind-energy/2731-pollution-free-energy.html
