What are hydroelectric generators?
Hydroelectric generators can turn the energy of movable water into usable electricity. This is most often achieved by damming the river and then by directing water over one or more turbines. Because the water causes turbines to rotate, electric generators operate. While dams may have an impact on the environment, hydroelectric generators are usually considered to be a primary source of pure renewable energy. About 20% of electricity in the world comes from hydroelectric generators that represent most of the electricity generated by renewable sources. RUN-of-RUE generators work in almost the same way as the traditional generators of dams and tanks, although they usually have small or no capacity of the tank. Instead of creating an artificial blockage of flow and changing height, the energy of the N-of-River energy uses the natural flow of water and the properties of the river. In order to produce consistent electricity, the runner must have a river on which it is installed on a usually permanently high flow of water. This is usually achieved inStalical turbine into a tidal zone that is operated by a daily inflow fluctuations. Sometimes it is possible to create tanks into these systems, allowing additional generator capacity in situations with high demand.
Another way to add additional capacity of the hydroelectric generator to the system is a drawn storage. This system can be used in conjunction with a traditional dam hydroelectric power plant or in a separate capacity. At a time when the demand for electricity in the area is low, the water can be pumped up to the high tank height. After the demand has increased, the stored water can be used to increase the generator capacity. These pump systems ultimately generate less energy than used to fill tanks, but the pumped storage for the production of a water offense can be a key method of storing the energy of the grid in some areas.
Some hydroelectric energy production may have environmental consequences, especiallyéna when it comes to large installations of dams. The potentially undesirable consequence of some dams is how they can effectively cut the ecosystem of the river. While some dams include ladders of fish that allow certain types to travel ascends to emerge, other fish may not be able to use them. This may disrupt the life cycle of some species or reduce the biological diversity of certain populations.
dams can also have positive effects, such as the provision of flood control and a reliable source for irrigation. Tanks can also be used for aquaculture and recreation. Unlike most electricity production, hydroelectric generators do not produce greenhouse gases such as carbon dioxide (CO 2 ). Some
