Hydroelectric Energy (Dams)
|The Bonneville Dam over the Columbia River in Oregon
Understanding a dam?
A dam is a man-made construction built across a lake. Many dams are built to regulate river circulation, enhance navigation, and regulate flooding. But some dams are made to produce hydroelectric energy.
How can dams make hydroelectric energy?
These are electric turbines inside a dam. Whenever liquid from dam passes through, the turbines spin. This produces electrical energy.
Hydroelectric power is created as liquid passes through a dam, and into a lake below. The greater amount of water that passes through a dam, the more energy sources are created. When a dam is built, an artificial man-made lake is made behind the dam.
Electrical energy is produced by a computer device called a turbine. Turbines contain steel coils surrounded by magnets. Whenever magnets spin throughout the metal coils, electricity is created. Turbines are observed inside dams. The falling liquid spins the magnets.
Dams offer clean, air pollution free energy, nonetheless they can also hurt environmental surroundings. Types that use rivers to spawn are often injured by dams. Into the Northwest, sockeye salmon and trout communities have dropped from 16 million to 2.5 million since hydroelectric flowers were constructed on the Columbia River. Dams all around the globe have injured some species.
What are the greatest dams in the U.S.?
Where may be the highest dam in the field?
