Transcript of Ocean Wave Power

Ocean Wave Power Wave power devices
extract energy directly
from surface waves or
from pressure fluctuations
below the surface. Wave power is the transport of energy
by ocean surface waves, using that energy
to do useful work, such as: electricity generation,
water desalination, or the pumping of water. benefits & advantages
- reduces the dependence upon fossil fuels
- is free, renewable, and clean source of energy
- produces clean electricity, no production of green house gases or pollution.
- highly efficent resource disadvantages & shortcomings
- not cost effective
- leads to displacement of wild life habitats
- it only produces electricity during tidal surges
- problems exist with the transportation of hydroelectricity wave energy technologies can replace fossil fuel - based power plants in the peak to medium scale baseload. ocean wave power was
originally founded in Rhode
Island, U.S.A. in 1978. It is being used
in other places as well. Are opinion of
this source of energy:
Yes, we should try and
use this source more because
it is clean, renewable source of
energy. It also does not produce
pollution. it has been estimated that improving technology and economies of scale will allow wave generators to produce electricity at a cost comparable to wind driven turbines, they produce energy at 4.5¢ kWh.

the best wave genarator technology in place in the UK
is producing energy at an average projected cost of 7.5¢ kWh.
in comparison electricity generated by large scale coal burning power
plants cost 2.6¢ kilowatt-hour. Installations have been built or are under construction in many countries, including: Scotland, Portugal, Norway, the U.S.A., China, Japan, Austrilia, and India.
