** tidal energy ** >>Tidal energy is the utilization of the sun and moons gravitational forces - as the tide is the result of their influences. >> It is a type of energy that produces electricity and other forms of power through the use of water. >> this could be obtained from the changing sea levels. In other words, tidal energy is a direct result of tide shifting from low to high. >>Tidal energy is one of the oldest forms of energy. Tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D. Tide mills consisted of a storage pond, filled by the incoming tide through a sluice and emptied during the outgoing tide through a water wheel. >>The tide moves a huge amount of water twice each day and although the tidal energy supply is reliable and plentiful, converting it into useful electrical power is not easy. ** There are two basic theories on how to convert tides into power. >>The first involves converting the power of the horizontal movement of the water into electricity. >>The second involves producing energy from the rise and drop of water levels.
