Running water produces electricity by turning turbines that activate massive power generators. This process involves the conversion of potential energy into kinetic energy, which in turn is transformed into mechanical energy and finally into electrical energy.
Water contains two basic forms of energy: potential and kinetic. Potential energy pertains to stored energy, while kinetic energy is the energy of motion. Hydroelectric plants are generally constructed by using dams to store water in reservoirs. Once water is released, its potential energy is converted into kinetic energy.
The turbines in hydroelectric facilities are positioned in such a way that the rapidly flowing water directly passes through them. The tremendous mechanical force that the running water exerts on the blades triggers the power generators, which are secured to the turbines. These machines then transform the mechanical energy into electricity.
