- and land use concerns.
4.
Hydropower
Hydropower is a renewable energy source that harnesses the energy of flowing or falling water to generate electricity. It typically involves the construction of dams on large rivers, where water is stored in reservoirs. When released, the water flows through turbines, converting kinetic energy into mechanical energy, which is then transformed into electrical energy. Hydropower is one of the oldest and most widely used forms of renewable energy, offering benefits such as low greenhouse gas emissions and the ability to provide a stable power supply. However, it can also impact aquatic ecosystems and local communities.
Pros
- Renewable
- low emissions
