Hydroelectricity is a renewable energy source that uses the potential energy of the water stored in the dams, reservoirs, flowing rivers etc. The falling or flowing water rotates the turbine which spins a generator and the mechanical energy of the generator is converted to electric energy and hence the electricity is generated from the water.

Hydroelectric Power Plant in India: Advantages and Disadvantages
Hydropower plants use water to produce electricity, which is a renewable energy resourceMultiple hydroelectric projects in India are inactive due to legal conflicts over the regional turmoil, environment, economic pressure, and unconcerned consumers
The process involves zero long-term costs as water is a renewable energy resource without any consumable elementsElectricity production using hydropower needs a substantial money investment in capital
It is less expensive as compared to power produced by gas-fired and coal plantsThey cause land submergence and result in the extinction of flora and fauna
It is more reliable and eradicates financial losses as it does not utilize fossil fuelsDiversion of forest land is periodically required since these projects are found in hilly regions, where forest cover is more
Hydropower stations are the best solution for fulfilling extreme loads in grids as they possess the ability to start and close immediatelyModern hydropower projects have experienced delays because of tricky planning strategies, long-term finance, lack of proper infrastructures, etc.


In India irrigation has always been the largest user of water. Irrigation projects mainly consists engineering (or hydraulic) structures which collect, convey, and deliver water to areas on which crops are grown. 

  • Irrigation is a method of watering.
  • It depicts an agricultural process that applies a controlled amount of water to the crop field for better products as well as to the horticultural land, social forestry lands, lawns, and fields for animal grazing.
