The water goes from the upper reservoir to the lower one, generating electricity in the process. Powerhouse Second reservoir 3 The turbine makes the generator turn, thereby producing electric energy. The water is returned to the river. Pipes Dam Pipes Energy Reservoir Turbine Powerhouse Second reservoir From the Dam to the City Powerhouse Reservoir 22,500 Electricity generated by the power plant is sent to a transformer, where its voltage is increased for transmission. The electrical energy circulates through high-voltage power grids over great distances.
Axle to generator Cracks and Fissures The magma from the mantle rises through cracks and fissures in the crust, heating rocks. The rocks heat the water contained in them. Organic fluid Steam to the condenser Heat exchanger Water from the deposit Axle to generator FLASH-STEAM POWER PLANT The most common type. The deposit provides hot water, generally at very high temperatures, which is vaporized in the plant to drive turbines and electrical generators. The water is then condensed and reinjected into the deposit.
3 Grid After leaving the wind farm, the electric energy can be incorporated into the main distribution grid. 4 Homes The electricity reaches the residential distribution grid and finally homes. 52 ENERGY RESOURCES ENERGY AND MOVEMENT 53 Diversion of the river Hydroelectric Energy Bypass Plant Charging chamber bout 20 percent of the world's electricity is generated by the force of rivers through the use of hydroelectric power plants. This technology, used since the 19th century, employs a renewable, nonpolluting resource, although the technology's impact on the environment is high.
