Hydropower is eco-friendly since it is fuelled by water and therefore it is a clean fuel source. They do not produce greenhouse gases like other fuels.
It is a domestic source because it can be produced in own states without depending on international sources for fuel.
Hydropower can be used as a backup power during major electrical disruptions because they facilitate quick to go from zero power to maximum output and hence generate electricity immediately.
Hydropower efforts are useful in flood control, water supply and irrigation.
Electricity is produced at a constant rate with cheaper price comparatively, once the dam is constructed.
Hydropower in the reservoirs recreates a variety of opportunities such as boating, fishing, swimming etc. which is accessed by the public to use these offers.
Disadvantages of Hydro energy
It is very expensive to build dams and finding a place suitable to build a dam is difficult.
The natural environment is destroyed.
The natural flow of water is sometimes changed due to which plants and animals in the water may get affected.
It is possible to affect wildlife and damage areas when they are flooded upstream.
During droughts, electricity generation becomes difficult and energy prices vary.
