Wind power is now the world's fastest growing energy source, according to Worldwatch.
As the technology to mass produce cheap electrical power from the wind advances, wind power is expected to play a much larger role in energy production.
The wind power information that our ancestors knew has helped them create a wind power system that could work on irrigation and furnaces. By 7th century the very first wind mill was made in Afghanistan.
The rate of growth of the wind energy systems has indeed been very rapid over the last few years. As a result, the wind power cost levels have fallen by around 80 per cent since the days when utility-grade wind energy units were used.
Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.
A drawback to wind power is that the wind can be erratic, changing direction by the hour.
Use of wind energy can reduce a residence’s energy costs by, on average, 50-90%, though these numbers are influenced by a variety of factors and, as such, can fluctuate greatly.
Wind power is more available during certain seasons as climatic conditions affect wind speed.
Industries of different types all over the world have started to utilize wind power.
Wind power is used to run large scale wind farms to run national electric grids.
