3. Introduction
 The ocean cover 75% of the world surface.
 It is the largest renewable energy source of
earth that can reduce greenhouse emissions.
 The ocean have power in different form i.e.
-wave energy
-tidal energy
-ocean temp. difference energy

4. OBJECTIVE
To reduce the use of fossil fuel.
Obtain the economical load scheduling.
For economical production cost choose as the base
load plant with diesel or gas power plant.
Reducing other auxiliary equipment i.e.-cooling
tower ash handling coal handling oil etc.
Avoid from various environmental issue i.e.
-greenhouse effect
-solid wastes
-acid rain etc

5. Broadly form of ocean energy
Wave energy
Tidal energy
[Ocean energy due to] temp. difference
of ocean water.
Note- we focused only above two topic

6. Wave energy

7. Tidal energy
Tidal energy is the potential difference
b/w tidal cycle head and tail. which is
carried by the action of sun and the
moon of the ocean water

8. Different techniques to make
useable of ocean energy
TIDAL BARRAGE

9. Utilization of wave energy
*It consist a
permagnet
shaft covered by
electrical coil when
magnet come in
motion flux
quantity varies and emf
Induced.

10. Wave capture device

11. How much energy and what types?
-250 Billion barrels of oil worth of energy coming into
ocean every day
-80 million barrels of oil per day produced
Theoretical global resource of 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 for ocean thermal energy
World’s electricity consumption 17,000 TWh/yr

12. Application
Power supplied light tower those navigates ship.
Power supplied cities those localized at shore of ocean.
Used for electrification of ship (floater power) .
Power supplied to grid.
 Individual power supplied for locally industries at the
shore of ocean (Tidal energy used)
Power supplied to communication tower that is used
for receiver, transmitter or repeater.

13. Advantages
Once you’ve built it then ocean power is free .
No greenhouse effect created.
No fuel requirement.
No any solid waste management problem.
 Reduces auxiliary equipment i.e. cooling tower
pre heater boiler etc.
Economical production cost.
Use as base power plant.

14. Disadvantage
Effect on marine ecosystem- as clean as
wave energy is it still creates hazards for
some of the animal near it.
Suitable to certain locations-the biggest
disadvantage to getting your energy from
the wave location. only power plants and
towns near the ocean will benifit directly
from it.

15. Conclusion
Ocean resources are immense yet diffuse
and expensive to exploit.
Its an energy that have big potential to be
more developed
In future this could represent another
solution in renewable source of energy so
that the management in this area could be a
more sustainable business.
