Question

What is the main basic cause for winds to blow? Name a part of India where the energy of wind is commercially harnessed.

Answer 1

Cause of Winds:

1. Uneven heating of the earth's surface causes the winds to blow.
2. Due to uneven heating of the earth's surface there exist temperature differences at various places on earth.
3. Due to this there exists a pressure difference which creates regions of low pressure and high pressure.
4. Air starts moving from the region of higher pressure to a region of low pressure to cause wind.

Places in India where wind energy is commercially harnessed:

1. Tamilnadu
2. Rajasthan
3. Madhya Pradesh
4. Maharashtra

These places have wind speeds greater than 15 $km/hr$ which is suitable for wind mill.
