Dams disrupt a river's ecosystem.
Hydroelecticity is very abundant and is considered a renewable resource because it will never run out. Many hydroelectic dams have be built in areas that aren't necessarily on a major river. But rivers have been diverted into man made reservoirs to create water pressure.
Basically from the sun. The warmth from the sun makes water evaporate, then winds(also caused by the sun) move the moisture about. Then it turns into rain, the rain drains into rivers, the rivers travel into dams, and the dams have turbines in them. As the power of the water turns the turbines, the turbines create electricity.
Electrical energy can be stored in batteries. Water energy can be stored behind dams.
Gravity dams:It is made up of masonry or solid concreteIt can be constructed to any heightLess maintenance
Low head dams pose hazards both above and below dams.They pose hazards both above and below dams
Backwash can pin you and the boat indefinitely.
Low-head dams are dangerous because people fail to realize that these dams are just as dangerous as larger dams. The movement of the water at the base can pull people under and trap them. These low-head dams have been nicknamed 'drowning machines.'
World Commission on Dams was created in 1998.
there can be all sorts along major rivers like dams statues.
There were 3 TVA dams on the Tennessee River in Alabama

Hoover Dam

Hydroelectric dams.
there are 4 major dams Sennar, Aswan High, Roseires and Owen Falls Dam
People in south America build dams on the major rivers to get more electricity. Plus, there is more industrialization in the area.
