Traditionally, waterfalls were used as a source of potential energy in which water is allowed to fall on the blades of the turbine where the rotatory motion of the blades of the turbine is converted into electrical energy. But waterfalls are few in number therefore water dams have been constructed. Nowadays, hydro-electric power stations are used in order to harness potential energy of stored water.
Earlier, the windmills were used to harness wind energy to do mechanical work such as lifting or drawing water from a well. But now a day’s windmills are used to generate electricity. In windmills the rotatory motion of the blades turns the blades of turbine to generate electricity.
