This stored water has potential energy due to its height. The higher the water is stored, the more potential energy it has. This potential energy is converted into kinetic energy when the water is released, which is then used to generate electricity.
1. Reservoir Creation: Dams create a large reservoir of water by blocking a river. This reservoir is vital because it stores water at a higher elevation, giving it the potential energy needed for electricity generation.
2. Water Flow Control: Dams also allow for the control of water flow. Engineers can regulate how much water is released at any given time, ensuring a consistent supply of water to the turbines.
