Introduction
Non conventional energy sources can be replenished in a short period of time.
There are basically five types which include tide, wind, solar, bio-mass and geo-thermal.
Tide is nothing but the natural rise and fall of coastal waters caused principally by the interaction of the gravitational fields of the sun and the moon.
What is tidal energy ?
Formation of tides depends on gravitational forces moments of sun, moon and earth.
The energy derived from ocean tides.
Formation of tides depends on gravitational forces moments of sun, moon and earth.
The energy derived from ocean tides.
How it works ?
The rotational period of the moon is around 4 weeks.
while one rotation of the earth takes 24 hours.
The tidal cycle of around 12.5 hours.
Conclusion
In present scenario tidal power has a potential to one day account for one fifth is our total consumption, so we have to effort more to improve the efficiency of tidal plants with modern technology.
