Tides are formed as a result of the gravitational pull of the moon. The tidal energy can be a solution to many of the energy related problems of the world. This movement of the water possesses a great deal of energy. The ocean energy technologies are reliable as it is based on the tried and tested principles of hydrodynamics and electrical engineering.

The tidal energy can be converted into power using two basic theories. One is by converting the horizontal movement of the water into electricity. The second is converting the rise and fall of the water into electricity. The conversion is done by passing the moving water into turbines which spin and generate electricity.

One of the best aspects of tidal energy is that its appearance can be deduced many years in advance. Therefore, this renders it the quality of being reliable and predictable. The advantages of the tidal power have led many investors to invest in tidal energy, in recent times.
