Dams are constructed world-over in a bid to harness electrical energy and also provide alternate essentials such as water for irrigation, industries and human consumption. Dam is a barrier to the free flow of water where water is stored, converting its kinetic energy into potential energy. Upon releasing the water, the potential energy again changes back to kinetic energy and is then used to work a turbine to produce electricity.
Watch the video to see world's five biggest dams by storage capacity i.e. the amount of water that can be stored in its reservoirs.
