The electricity which is generated with the help of fast currents of flowing water is termed as hydropower or hydroelectricity. The main components of hydropower plants are Rivers, Dams, and Turbines where the abundance of water is stored in the reservoir from where the water is released through turbines spinning it at a very fast speed which helps in generating the electricity. If we speak today, hydropower is the most important and widely used source of the renewable form of energy. China is the largest producer of hydroelectricity in the world. Hydropower uses the water as a fuel and as we all are aware of fact that on planet earth water is not perishable and is available in abundance of this earth, that’s why much emphasis is given to hydroelectricity and it is the most effective and efficient method of generating electricity besides being most reliable and affordable source as compared to fossil fuel like coal, gas, and petrol. The main advantage of hydropower is that it is a clean source of fuel which consists of water as fuel which is not at all going to have any effect/impact on the environment as compared to the burning of coal petrol etc. Moreover, since in countries like India having 23 states and each state is fully equipped with its water resources in terms of dams, reservoir etc they can generate electricity independently as and when required without being relying on other states for wants of both domestic and industrial electrical needs.
