Green Energy is the need of the time. In this video I am explaining how Hydro Electricity is generated. Hydroelectricity is the term referring to electricity generated by Hydropower plants. capture the gravitational force or energy of falling water to generate electricity. It is most widely used renewable energy, accounting for 26% of the Worlds electrical energy. The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity. The average cost of electricity from a hydro station larger than 10 megawatts is 3 to 5 U.S. cents per kilowatt-hour. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a Penstock to the turbine and spin it. A turbine converts the kinetic energy of falling water into mechanical energy, which in turn activates a generator to produce electricity. Then a generator converts the mechanical energy from the turbine into electrical energy. Another type of hydroelectric power plant - called a pumped storage plant - can even store power. The power is sent from a power grid into the electric generators. The generators then spin the turbines backward, which causes the turbines to pump water from a river or lower reservoir to an upper reservoir, where the power is stored. To use the power, the water is released from the upper reservoir back down into the river or lower reservoir. This spins the turbines forward, activating the generators to produce electricity. I've also explained the importance of hydrologic cycle in the video. Facebook Page: https://www.facebook.com/rocketscienceletsrockit Go Green & with Us let's Rock it!
