Wind Energy
The energy obtained from the wind is called wind energy. The wind contains kinetic energy which can be used to harness energy by converting it to mechanical energy by the use of wind mill. Although wind energy has been used by us for a long time, it was used in propelling the sails of the ship in ancient times.
Advantages
- Like solar energy, it is also a renewable form of energy.
- It does not cause any air pollution or global warming by releasing harmful gases.
- It is space efficient and requires very little space on the land surface and the land between two windmills can be used for agriculture and other different purposes.
Disadvantages
- It is very location specific as windmills cannot be set up in all places. It can only be installed at places where there is strong winds
- It is very costly to set up and difficult to repair.
- Storms and cyclones cause great damage to windmills.
Now having understood the advantages and disadvantages of wind energy, let’s understand the working of a windmill and how it produces energy.
A windmill is a tall tower-like structure having blades (mostly three). Under the influence of winds, these blades rotate and these rotate the coil connected to the blades. This coil is placed between the North and south pole of the magnet which acts as an electric generator and produces electricity.
Non-Conventional Sources of Energy
Can you picture driving a car that is powered by water? Or one that is powered by the Sun? The fact is that you may have to become used to such outlandish thoughts. Conventional fuels are increasingly running out, while non-conventional energy sources are becoming our future. And, in order to run them, let us study more about non-conventional energy sources.
Energy is a critical component of the economic infrastructure, as it is the primary input required to support economic growth. Economic development and energy usage have a close relationship. The greater a country’s per capita energy usage, the more developed it is, and vice versa. Human civilization is reliant on a variety of energy sources. In this article, we will discuss the non-conventional sources of energy and their usage, advantages, and disadvantages. Before, that let’s first understand what is energy.
