What is Wind Energy?

The wind is an inexpensive, reliable, and cleaner source of energy.

Generation of Wind Energy

  • Windmills are used for generating electricity. The blades of the windmill rotate due to the force of the wind. This rotational motion of the blades is used for driving a number of machines such as water pumps, flourmills, and electric generators.
  • Several wind farms are installed in a definite pattern in clusters called ‘wind farms’. Wind farms are generally installed in coastal regions, open grasslands, and hilly regions. The Indian wind programme is the fifth largest in the world.
  • In India, the largest wind farm cluster is located from Many housing societies have started installing solar panels on the top of their house for lightening lobbies and heating water. The largest wind farm in India is situated from Nagarcoil to Madurai in the state of Tamil Nadu Nagarcoil to Madurai in Tamil Nadu. Important wind farms are also located in the states of Andhra Pradesh, Gujarat, Kerala, Lakshadweep, and Maharashtra.

Advantages of Wind Energy

  • It is a renewable source of energy.
  • It does not produce pollution. Thus, it is a cleaner source of energy.
  • It reduces our dependence on fossil fuels.
  • Wind turbines can be built on existing agricultural farms. This greatly benefits the economy in rural areas, where most of the best wind sites are found.
  • Landowners can earn additional income by installing wind turbines on land that can be used for domestic consumption.


Conventional Sources of Energy

Coal is an important mineral in India. It occurs as a sedimentary rock in association with carbonaceous shale, sandstone, and fine clay. Coal was formed by the decomposition of large land plants and trees buried under the Earth about 300 million years ago. Read more

Non-Conventional Sources of Energy

Non-conventional sources of energy are also known as renewable or alternative sources of energy. These resources have been developed in the recent past as an alternative to conventional or non-renewable sources of energy. Some examples are wind energy, solar energy, geothermal energy, tidal energy, and biogas. Non-conventional resources are known as energy resources of the future. Read more
