उत्तर
| Advantages of hydroelectric power plant | Disadvantage of hydroelectric power plant |
| i. No fuel is burnt in a hydroelectric power plant. Thus, no air pollution due to combustion of fuel occurs. | i. Villages, towns, forests may submerge due to back-water caused by the storage of water in dams. This leads to forced migration of the living population in that area. |
| ii. Electricity can be generated whenever required if the dam has sufficient water storage. | ii. The obstruction of the flow of river water may have adverse effect on the living world in the river. |
| iii. During rainy season, the water in the water reservoirs can be replenished and used for power generation. |
