Energy From Flowing Water - Hydro Energy:
When we talk of flowing water, we think of water flowing in rivers, streams, waterfalls, and so on.
The flowing water has kinetic energy. The ultimate source of this energy is the sun. This is because the energy of the sun evaporates water, which forms clouds that cause rainfall or snowfall. The rain and melting snow feed rivers, etc., whose flow we use.The energy of flowing water has been used for centuries to carry logs down rivers, to turn waterwheels to grind grain, run mills, and so on. Water striking the blades of the waterwheel makes it rotate. This design was modified to make water turbines, which are used to generate electricity from flowing water.
