The languid nature of tides occurring in the seas and the ocean should not be mistaken for its appearance as these carry some of the greatest forces of nature. The tides are highly dense and can deliver high energy outputs. The tidal power comes under the ocean energy technologies that have been based on years of knowledge collected from tried and tested principles of hydrodynamic physics and electrical engineering.

The tides are highly reliable entities that occur very predictably. In fact, their presence can be deduced many centuries in advance. That delivers tidal energy a very high sense of dependency. The occurrence of any tide can be found out from the tide table available in the surf stores near beaches. This is one of best reasons people are going for tidal power, resulting in a growth of tidal power investment.

Tidal power can be generated using tidal turbines. Very similar to the wind turbine, the tidal turbines make use of the ocean currents to create energy. The tidal turbines are smaller than the wind turbines. The tidal turbines producing 1MW of power can be one third the size of a wind turbine of similar capacity.
