Hidrelétricos

Hidrelétricos refers to hydroelectric power plants, which generate electricity from the energy of moving water. These facilities typically consist of a dam built across a river to create a reservoir. The stored water is then released through turbines, causing them to spin. This rotation drives generators, which produce electrical energy. The amount of electricity generated depends on the volume of water flowing through the turbines and the height of the dam, known as the head.

Hydroelectric power is considered a renewable energy source because it relies on the natural water cycle. The construction of dams can have significant environmental and social impacts. These include altering river ecosystems, displacing communities, and changing land use. However, hydroelectricity is also a source of reliable and often cost-effective electricity. It can also provide benefits such as flood control and water supply for irrigation.

The technology for hydroelectric power has been in use for over a century and continues to be a major contributor to global electricity generation. Many countries have substantial hydroelectric capacity as a key part of their energy infrastructure. The development of new hydroelectric projects is often subject to extensive environmental reviews and public consultations.
