Ocean Waves Power 2
EXECUTIVE SUMMARY
The ocean wave energy is produced as a result of the winds interacting with the ocean
surface. The process of extraction of wave power does not emit carbon dioxide or generate any
waste. The wave power can be generated in the entire year compared to other renewable energy
sources. The attainable energy flux in the wave energy is greater than the energy flux attainable
from wind or solar renewable sources. Specifically, a small quantity of the wave power is used
for the commercial generation of electric power currently out of the huge quantity of energy
stored in the waves. The extreme waves under the sea and ocean water do not modify the coastal
and marine ecosystems at the sites in which they impact but may also produce larger-scale
effects through the alteration of connectivity, the movement of energy, materials, and organisms
between habitat units within seascapes. One of the available technique techniques of deriving the
efficient location for setting up the plant of energy generation which can provide minimum
maintenance and setup cost with maximum power is the use of wave energy converter (WEC).

INTRODUCTION
The consumption of power all over the world is estimated to increase over the coming
years. The traditional methods of power generation are contributing to the extreme
environmental effects that are still ambiguous. The problems associated with the use of fossil
fuels have brought the technologies of renewable energy under the spotlight. Some of the
emerging energy sources for the renewable energy include geothermal, biomass, ocean, solar,
and wind. The ocean energy sources are one of the most imminent energy source for biomass,
solar, and wind sources. Approximately 70% of the surface of the earth is covered with oceans
which involve the abundant quantity of energy in the form of thermal gradient, marine current,
tidal, and wave.
The wave power can be generated in the entire year compared to other renewable energy
sources. The attainable energy flux in the wave energy is greater than the energy flux attainable
from wind or solar renewable sources. The literature review below evaluate the available past
and present literature regarding the ocean wave power generation and provides the possible gaps
and information to do development implementation, and further research in the future (Baddour,
2010).
LITERATURE REVIEW
The waves referred to in this proposal are ocean waves generated by the wind. During the
shinning of the sun on the world, there is heating of the air resulting to the difference in pressure
that are the engines that propagate the winds. The energy from the sun can then be concentrated
in or transferred to the wind. The wave energy can be captured at either onshore or offshore.
There are numerous types of potentially efficient devices that have been identified which require

not larger compared to the commonplace in shipbuilding. There are numerous methods that can
be used in concentrating ocean wave energy which is commonly known as Wave Energy
Converters. The generators can be positioned on the seashore to protect it from extreme waves of
the sea surface (Charlier, 2011).
At Uppsala University in Sweden, the Renewable Electric Energy Conversion project
using the permanent magnet linear generated positioned on the coastal region where the wave
energy converters are impelled by point absorbing floating buoy to produce electricity. In the
current experiment, a wave energy converter has been joined to the diverse resistive loads, ultra-
capacitors, and diode rectifier. The outcomes denote that the generator loads is beneficial when
the generation of power is to be maximized. The average power absorbed increases with a
decreasing resistive load (Danielsson, 2008).
Some of the factors that have affected the development of the systems of wave energy
include testing huge prototypes under severe environmental conditions, deploying, and high
costs of construction. The efficient power or energy pulling from the waves composed of
practical and technical; challenges and the most perplexing is to derive the wave behaviour
accurately as it relies on the friction between the surface water and wind of the ocean. The
extracted power from the ocean waves by the WEC depends on the control strategy, power off-
shore site, hydrodynamic characteristics of the device, and also the wave conditions at the site
off-shore (Gerald, 2009).
The process of energy harvesting is attained through converting the wave energy of
Transverse Ocean to the electrical energy through the piezoelectric patches attached on the
cantilevers secured on the buoy. A point absorber wave extractor is then established with two
systems of the coaxial cylinder. The system is composed of the outer cylinder which oscillates
