i. Advantages of hydroelectric power generation:
i. No fuel is burnt in a hydroelectric power generation. Thus, no air pollution due to combustion of fuel occurs.
ii. Electricity can be generated whenever required if the dam has sufficient water storage.
iii. During rainy season, the water in the water reservoirs can be replenished and used for power generation.
Disadvantages of hydroelectric power plant:
a. Villages, towns, forests may submerge due to back-water caused by storage of water in dams. This leads to
b. The obstruction of the flowing population in that area.
ii. Hydroelectric power plant offers the advantage of providing clean and renewable electricity without the need for the combustion of fossil fuel, but the construction and operation of hydroelectric power plants can cause damage to wildlife habitats and have an adverse effect on the living world in the river
