Question

In India, Hydroelectric power contributes approximately ______ percent of the total electricity produced. a) 44% b) 22% c) 55% d) 3%

Answer 1

Answer:

The correct answer is approximately 22%. The contribution of hydroelectric power in the total power generated in India is very significant.

• Dams are built in India for multipurpose. It is used as a facility for recreation, the water stored can be used for irrigation purposes, and very important dams are used for generating hydroelectric power.
• Hydroelectric power is a very important component among different renewable sources of energy.
• First Prime Minister of India said dams are the modern temples of India.

Important Hydroelectric Power plants of India

Some of the important Hydroelectric power plants of India are listed below:

• Damodar Valley Project
• Nagarjunasagar
• Gandhi Sagar
• Bhakra Nangal

Hydroelectric Power – World’s share

• Almost one-fourth of the world’s power i.e. contribution of around 25% of the power generated across the globe comes from Hydroelectric power.

Hydroelectric Power – Leading Producers of the World

• Some of the leading producers of Hydroelectric power across the globe are China, Brazil, Norway, Paraguay (located in South America), etc.

Hydroelectric Power Plants – How Power is Generated

• Water is collected in larger reservoirs by obstructing the flow of water in the river.
• The flow of river water is obstructed by building high-rise dams across the river.
• As the stored water level rises, the kinetic energy of the river water gets converted into potential energy.
• Through pipes, water is carried from the high level in the dams to the turbines which are located at the bottom of the dam. Turbines are connected to the power generator.
• Each time when it rains, the water gets refilled in the reservoir, hence hydropower is a renewable source of energy.
