Introduction to producing wind energy
Wind is a source of energy that has been harnessed for different applications since a long time.
The Chinese and the Babylonians have been famous for using wind power for the pumping of water for irrigation of crops some 4,000 years back.
And in addition to this, sailing boats were harnessing wind power long before that.
It has been recorded that wind power was used in Europe in the Middle Ages for other activities like grinding of corn.
In fact, this is what has been attributed to the start of the term windmill. To understand the concept of wind power, it is better to first understand the science behind wind formation.
With the sun heating the atmosphere unevenly, some patches of land become warmer than others; and this is where warm patches of air rise. With this, other air starts blowing to replace them and start a wind blowing. The energy produced from the wind is used by building a tall tower which has a large propeller on its top.
