The primary source of power generation in Assam is:

Hydropower
Coal
Natural Gas
Solar

The primary source of power generation in Assam is hydropower. In 2020, hydropower accounted for 62% of the state’s electricity generation, followed by coal (27%), natural gas (9%), and solar (2%).

Hydropower is a renewable energy source that uses the power of moving water to generate electricity. It is a clean and efficient way to produce electricity, and it does not produce greenhouse gases. However, hydropower projects can have a negative impact on the environment, such as by disrupting fish migration and altering water flows.

Coal is a fossil fuel that is used to generate electricity. It is a non-renewable energy source, and it produces greenhouse gases when it is burned. Coal is a major source of electricity in India, and Assam is one of the country’s largest producers of coal.

Natural gas is a fossil fuel that is used to generate electricity. It is a cleaner-burning fuel than coal, and it does not produce as many greenhouse gases. Natural gas is a relatively new source of electricity in India, but it is becoming increasingly popular.

Solar energy is a renewable energy source that uses the sun’s rays to generate electricity. It is a clean and efficient way to produce electricity, and it does not produce greenhouse gases. However, solar energy is intermittent, meaning that it is not available at night or during cloudy weather.

In conclusion, the primary source of power generation in Assam is hydropower. Hydropower is a clean and efficient way to produce electricity, but it can have a negative impact on the environment. Coal is a major source of electricity in India, but it is a non-renewable energy source that produces greenhouse gases. Natural gas is a cleaner-burning fuel than coal, but it is a relatively new source of electricity in India. Solar energy is a clean and efficient way to produce electricity, but it is intermittent.
