⚫Theocean cover 75% of theworld surface.
⚫It is the largest renewable energy source of
earth thatcan reduce greenhouseemissions.
⚫ Theocean havepower in different form i.e.
-ocean temp. differenceenergy
To reduce the useof fossil fuel.
Obtain theeconomical load scheduling.
Foreconomical production costchooseas the base
load plant with diesel orgas powerplant.
Reducing otherauxiliary equipment i.e.-cooling
towerash handling coal handling oil etc.
Avoid from variousenvironmental issue i.e.
-acid rain etc
Broadly form of ocean energy
[Ocean energydue to] temp. difference
Note- we focused onlyabove twotopic
How much energy and what types?
-250 Billion barrelsof oil worth of energy coming into
-80 million barrels of oil perday produced
Theoretical global resourceof ocean energy:
8,000-80,000 TWh/yr for wave energy 800 TWh/yr for
tidal current energy 2,000 TWh/yr for salinity gradient
energy 10,000 TWh/yr forocean thermal energy
World’selectricityconsumption 17,000 TWh/yr

Onceyou’ve built it then ocean power is free .
No fuel requirement.
Noany solid waste managementproblem.
Reduces auxiliary equipment i.e. cooling tower

Economical production cost.
Useas base powerplant.
Effect on marine ecosystem- as clean as
wave energy is it still creates hazards for
someof theanimal near it.
Suitable to certain locations-the biggest
disadvantage togetting yourenergy from
thewave location. only powerplants and
towns near the ocean will benifit directly
Ocean resources are immenseyetdiffuse
and expensive toexploit.
Itsan energy that have big potential to be
In future this could represent another
solution in renewable source of energy so
that the management in this areacould be a
more sustainable business.
