Question

Accepted Answer

Hydroelectric power plants harness the kinetic energy of flowing water or potential energy of stored water to generate electricity. Advantages: 1. It is a renewable source of energy that does not produce greenhouse gases or direct air pollution during operation. 2. Dams constructed for this purpose help in flood control, irrigation, and providing a steady water supply. Disadvantages: 1. Construction of large dams submerges vast areas of agricultural land, forests, and human settlements, displacing local communities and destroying ecosystems. 2. It disrupts the natural flow of rivers, affecting aquatic life and migratory fish species. Furthermore, large-scale dams can sometimes trigger ecological imbalances and seismic activity.
