Question

What is the source of electricity?
Explain the various power stations in India?

Answer 1

1. In thermal power stations, thermal energy is generated by burning coal, diesel, or gas to produce steam.
2. Steam is used to rotate the turbine to generate electricity.
3. Here heat energy is converted into electric energy.

• Hydel power stations:

1. In hydel power stations, the turbine is made to rotate by the flow of water from dams.
2. Here kinetic energy is converted into electric energy.

• Atomic power station:

1. Here nuclear energy is used to boil water
2. The steam thus produced is used to rotate the turbine, as a result, electricity is produced.
3. Here nuclear energy is converted into mechanical energy.

• Windmills:

1. In windmills, wind energy is used to rotate turbines to produce electricity.
2. Here kinetic energy is converted into electrical energy.
