Nuclear power contributes only 9% to 10% of the total electricity produced worldwide. Although this may seem quite low, it makes nuclear energy one of the major clean energy sources. Because nuclear power plants produce electricity without burning coal, gas or oil, they help reduce carbon emissions.

Nuclear power is the second largest source of low carbon electricity worldwide after hydro power. Nuclear power is used by many countries to meet climate goals, as it provides continuous electricity without emitting greenhouse gases during operation.

Some countries are heavily dependent on nuclear energy for their electricity needs. France generates about 67% of its electricity from nuclear reactors. Similarly, Hungary also gets about 47% of its electricity from nuclear energy.

Nuclear energy contributes about three percent of the total electricity generated in India. Although this part is quite small, yet it plays an important supporting role in the power grid of the country. At present, coal is used most in India for electricity generation.

At present India is operating 25 nuclear reactors with a total installed capacity of 8880 MW. These reactors use heavy water technology and are located in many states like Maharashtra, Rajasthan, Tamil Nadu, Karnataka and Gujarat. Nuclear energy contributed 56.7 billion units to India’s approximately 1830 billion units of electricity production in the financial year 2024-25.

India aims to reach 100 gigawatt nuclear power capacity by 2047. Recognizing the need for cleaner and more diverse energy, the Government of India wants to expand nuclear energy capacity.
