           TIDAL ENERGY
*Form of water power that occurs in the ocean
* Converts the energy of tides into electricity
             TIDAL ENERGY
* Renewable resource because it can be replenished
* Caused by the Moon’s gravity which will last a long
  time
          TIDAL ENERGY
* Tidal Energy = Tidal Power = Ocean Energy
             TIDAL ENERGY
* Tidal energy is
  the result of the
  Moon’s
  gravitational
  attraction on
  Earth and the way
  the moon’s gravity
  pulls the oceans in
  a bulge as the
  Moon orbits Earth
  – the tide must
  raise the water at
  least 10 feet
         TIDAL ENERGY
* Tidal Energy Power Plants are in Canada,
  Ireland, and France
