Write an essay on hydel power in India.

● Hydel Power is a nonconventional source of energy.


● It is a renewable form of energy as it uses the earth's water cycle to generate electricity.


● The water from the Earth's surface evaporates to form the clouds.


● It later precipitates back to the earth and flows towards the ocean in the form of rain.


● This movement of water as it flows downstream creates kinetic energy that can be converted into electricity.


● Out of the total power generation installed capacity in India, the Hydel power contributes about 21.5%.


● In the eleventh plan, it was proposed to have a capacity addition of approximately 78700 MW from different conventional sources.


● Out of this 15627 MW was expected to be gained from large hydropower projects.


● 14000 MW was expected from small hydel power Projects up to 25 MW station capacity.


● The total hydroelectric power potential in the country is approximately 150000 MW, and the potential of small hydropower projects is approximately 15000 MW.


● The hydroelectric power plant consists of a high dam that is built across a large river to create a Reservoir and station where the process of energy conversion to Electricity occurs.


● Firstly the runoff of seasonal rain and snow in different water bodies that occur in a hydrological cycle is collected.


● The runoff flows to dams downstream.


● The waterfalls through a dam into the hydropower plant and turn a large wheel called a turbine.


● The turbine converts the energy of falling water into mechanical energy.


● This electricity is transferred to the communities to transmission lines, and the water is released back into the water bodies.


● India is ranked fifth in terms of potential hydropower in the Global terms.


● 56 number of pump storage project has been identified with an installed capacity of 94000 MW.
