Introduction
Tide is a periodic rise and fall of the water level of sea. Which are create by the action of the and moon on the water of the earth.
The large scale up and down moment of sea water represents an unlimited source of energy can be converted into electrical energy.
The tidal energy could be converted into electrical energy by means of turbine-generator set.
Energy From The Moon
Tides generated by the combination of the moon and sun’s gravitational forces.
Greatest affect in spring when moon and sun combine forces.
Bays and inlets amplify the height of the tide.
In order to be practical for energy production, the height difference needs to be at least 5 meters.
Only 40 sites around the world of this magnitude.
Overall potential of 3000 gigawatts from movement of tides.
Basic Principle of Tidal Power
Incoming And Outgoing Tides
Types of Turbines
Bulb Turbine
Rim Turbine
Tubular Turbine
Marine Current Turbines
Components of Tidal Power Plant
The power house.
The dam or barrage.
Sluice way from the basins to the sea.
Advantages
Renewable.
Abundant.
Pollution free.
Water is a free resource
Presents no difficulty to migrating aquatic animals.
It is independent of rain and its uncertainty.
Tidal power plants don’t demand large area of land.
Disadvantages
Disturbance to marine life.
Expensive to construct.
No reliability.
Cost of Maintenance is Higher.
Power transmission from offshore facilities harder.
Bed power quality.
Conclusion
By using tidal energy we can produce 16% of world’s energy but the main drawback of it is the cost factor. It is very expensive(estimated about $ 1.2 billion).
