3. How tides are formed… The gravitational forces of the sun and the  Moon  combined with the rotation of the earth result in an alternate rise and fall of the sea levels. The periodic rise and fall of sea water level is called a Tide. The rise of the sea level is called the high tide or flood tide, whereas the fall is called the low tide or ebb tide. Unlike the wind, the tides are very predictable. So it’s easy to decide where to put tidal turbines and figure out how much energy they will generate. Additionally, the turbines are usually entirely underwater, so no one can complain about them spoiling the view!

4. Tidal range… The tidal range is the difference between consecutive high tide and low tide water level. It is denoted by R and is measured in meters. The tidal range varies from time to time, season to season and its location. The maximum tidal range occurs at the time of new and full moon called spring tides. The total tidal energy of the world is estimated to be 3x106MW.

6. What is Tidal energy…? The energy obtained from the rise and fall of tides is called the tidal energy . It is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows,  and turns it into usable electricity. 

7. Working Principle For utilization of tidal energy, water must be trapped at high tide behind a dam or barrage and then made to drive turbine coupled to an electric generator as it returns to sea during low tides.

8. Main Components… These are the main components of a tidal power plant :- Dam to form basin Turbine & Generator Sluice Gates

9. DAM The function of  dam  is to form a barrier between the sea and the basin. The barrage needs to provide channels for the turbines with prestressed or reinforced concrete.

10. TURBINE & GENERATOR

11. SLUICE GATES Sluice gates are the main part of the tidal power plant that allows water to flow through the turbines and generate electricity. It also allows the tidal basin to fill on the incoming high and low tides and to empty through the turbine on the outgoing tide.
