उत्तर
Advantages of Hydroelectric Power Plants:
- Hydroelectric power generation does not require the burning of fuels; therefore, it does not cause air pollution or release toxic gases.
- Electricity can be generated whenever required, provided there is sufficient water in the reservoir.
- Water is a renewable resource and is replenished through rainfall.
- Hydroelectric power is a clean and renewable energy source.
Disadvantages of Hydroelectric Power Plants:
- The construction of dams and reservoirs submerges villages and settlements, displacing people.
- Rehabilitation of displaced people often causes social and emotional problems.
- Forest areas may be submerged, resulting in loss of biodiversity.
- Dams obstruct the natural flow of rivers, affecting aquatic plants and animals.
- The large pressure exerted by stored water may increase the risk of earthquakes in some regions.
