The primary source of electricity generation in Bihar is:

Coal-based thermal power plants
Hydropower
Solar power
Wind power

The primary source of electricity generation in Bihar is coal-based thermal power plants. In 2020, coal-based thermal power plants generated 85% of the electricity in Bihar. Hydropower generated 10%, solar power generated 3%, and wind power generated 2%.

Coal-based thermal power plants are the most common type of power plant in India. They use coal to generate heat, which is then used to turn water into steam. The steam drives a turbine, which generates electricity.

Hydropower plants use the power of moving water to generate electricity. They are usually built on rivers or dams. The water flows through a turbine, which generates electricity.

Solar power plants use the sun’s energy to generate electricity. They are usually made up of solar panels, which convert sunlight into electricity.

Wind power plants use the wind to generate electricity. They are usually made up of wind turbines, which turn in the wind and generate electricity.

Coal-based thermal power plants are the most polluting type of power plant. They emit large amounts of carbon dioxide, which contributes to climate change. Hydropower plants can have a negative impact on the environment, as they can disrupt the flow of rivers and damage ecosystems. Solar power plants and wind power plants are clean and renewable sources of energy, but they can be expensive to build and maintain.
