How has the traditional use of wind and water energy been modified for our convenience?

(N/A) Traditionally,waterfalls were used as a source of potential energy,which was converted into electricity with the help of turbines. Since waterfalls are limited,large-scale water dams have been constructed. Nowadays,hydroelectric dams are used to harness the potential energy of stored water. In these dams,water falls from a height onto a turbine,which rotates to produce electricity.
Earlier,windmills were primarily used to perform mechanical work,such as drawing water from a well or grinding grain. Today,modern windmills (wind turbines) are used to generate electricity. In these systems,the kinetic energy of the wind is harnessed to rotate the blades,which in turn rotate the turbine of an electric generator to produce electricity.
