Jun 03, 2020· Hydroelectric power plants convert the potential energy of stored water or kinetic energy of running water into electric power. Hydroelectric power plants are renewable sources of energy as the water available is self-replenishing and there are no carbon emissions in the process. In this article, we'll discuss the details and basic operations of a hydroelectric power plant.
