List three source of hydroelectric power

Here are three sources of hydroelectric power:

1. Rivers: Dams are constructed across rivers to create reservoirs. The stored water is then released through turbines to generate electricity.
2. Waterfalls: Natural or artificial waterfalls provide a significant drop in elevation. The potential energy of the water is converted into kinetic energy as it falls, which can then drive turbines.
3. Tidal Movements: The rise and fall of ocean tides can be harnessed. Barrages or turbines are placed in estuaries or bays to capture the energy from tidal flows.
