Wind energy is one of the least tapped sources of alternate energy. The amount of Wind power available in the atmosphere is so high that it can satisfy the demands of the whole world. Studies revealed that the potential of wind power on land and near-shore is calculated to be 72 terrawatts (TW). This is over five times the world's current energy consumption in all forms.
The
investments in wind power have gone up because of many new technologies coming up in the wind sector. Currently the usage of wind power is only 1% but this is growing so rapidly, almost fivefold between 2000 and 2007. The growth of usage of wind energy is deduced to be around 21% per year. The maximum output from the wind powered generators is around 94.1 GW.
Wind energy is clean as well as cheap. Environmentalists strongly recommend its usage as an alternate source of energy, owing to its environment-friendly qualities and lack of production of any harmful gases. The conventional sources of energy like the fossil fuels are known for their harmful effects on earth and the depleting ozone layer, caused by the emission of pollutants while using these fuels.
