TIDAL+ENERGY+-+Lauren

= TIDAL ENERGY =  Tidal Energy is a form of hydro-power that converts the energy of tides into electricity or other useful forms of power. It is one of the oldest forms of energy used by humans. They were originally used on the Spanish, French and British coasts.

HOW IT WORKS
Large underwater turbines are placed in areas with at least 15 feet increase between low and high tide. The turbines then capture the kinetic motion of the tides. The turbines flow due to the water from the tide coming in, this generates electricity.


 * The Energy Changes Involved: **Gravitational Potential Energy (Tides) >> Kinetic Energy >> Electrical Energy

Example - Rance, France
On the Rance river, France one of the few barrage methods is used to create electricity. The barrage method involves turbines installed in a barrage across a bay or river to generate power from the flower water in and out of the estuary. Only a few of these plants exist - the largest being the Rance Tidal Power Station, which was opened in 1966, and generates 240MV. Another barrage plant is the one on the Bay of Fundy, and another in Kislaya Guba, Russia. ==== ====

Benefits

 * Renewable energy does
 * Does not release acid, harmful fluids and gases
 * Reasonable substitute for nuclear energy - therefore can protect us from nuclear radiations.
 * Can be helpful in increasing the efficiency of traditional power grids.
 * Can also replace other conventional power projects which release greenhouse gases and acids.
