In olden days, wind energy was trapped used windmills to do mechanical works like lifting or drawing water from a well. But these days, windmills are used to generate electricity. The kinetic energy of wind is trapped and converted into electricity with the help of rotatory motion of the blades which turns the turbine of the electric generator to produce electricity.
Similarly, waterfalls were the source of potential energy in olden days. But these days, as the number of waterfalls as reduced, water dams are constructed and are used as a source to trap the potential energy. Here, the water falls from a certain height on the turbine producing electricity.
