Possibilities: In 2016, India's potential for hydro-electricity was 42.8 thousand megawatts, but only 14.4% of this potential has been developed so far. About 60% of India's estimated hydro-electricity sources are in rivers originating from the Himalayas, such as the Brahmaputra, Ganga, and Indus and their branches. Another 20% of this power is in the rivers of the south that flow from north to south and west to southeast. The remaining 20% is in the Western Ghats and rivers from central India flowing from east to west. This highlights a vast untapped potential that can be utilized for sustainable development.
In simple words: India makes a lot of electricity from water, called hydro-electricity. We have a lot of rivers, especially in the Himalayas, that can make even more electricity. But we are only using a small part of this potential right now.
