Tidal and Waves Energy By: Paola Cevallos and Micaela Moncayo
≈MICPA ≈ S.AA company which is based on renewable energy, solutions
for the near future.Development is not a synonym of destruction.!
What is a wave? Creating energy with the oceanA wave is a reaction of movement to the mixture
of certain subtances found in the wind and the oceans surface.
We are able to use that constant movement to create energy.
What is tidal? A tidal is the movement of currents along the ocean, the rising
and falling of large bodies of water. A tidal is form because of the moons gravitational atraction. Since the moon and the earth atract each to other, the moon pulls
everything on earth towards it, the earth holds on onto everything except the ocean.
DescriptionThis type of energy (tidal & waves) comes
from seas & oceans that are usually recovered from water turbines with the movement of waves and tides that are produced in the water. In Ecuador it should be a good idea putting this turbine technology in any coast of the country.
Renewable or Non-renewable energy source? Tidal and waves is a renewable energy because it uses
water which is at least 70% of the Earth´s surface and is not a limited resource for example like fossil fuels. This form of energy is a motion type of energy because it needs the power from the movement of waves and tides to create energy recovered with water turbines.
Where and how can we harness itThis energy source is found on the movement
from water in oceans and seas. With this movement produced, they invented a thing called water turbines that use this motion from water (tides and waves) and when they pass through this turbine they create movement that motors the generator inside that produces energy for a whole population.
Stored and Release energyThe energy is stored in the
oceans as thermal energy, also as kinetic energy (waves and currents) and in chemical and biological products.
Tidal and waves energy is released with the motion from the water that later transforms to other types of energies. For example it is transform to sound energy from the movement of waves that crush with the coast.
History TIDAL ENERGY: 787: simple technique of a waterwheel by the Spanish, French, and British 1966: “La Rance” tidal power plant went in operation. 2001: British Parliament states “the world can no longer neglect the
massive potential of wave and tidal energy” 2002-present: Large investments in research and prototypes spark
proposals in Turkey, China, and United States; among others WAVE ENERGY: 1799: First patent of a device designed to use ocean waves to generate
power 1910: First oscillating water column was built by Bochaux-Praceique to
power his house 1940s: Yoshio Masuda experimented with many concepts of wave power 2004: Wave power was delivered to an electrical grid for the first time
Today Barrage Tidal Power: Rance coast Station: Located on Rance Coast, France
750 meters long24 TurbinesCapacity of 240MWAnnual output of 600GWh Supplies 0.012% of Frances power supply.Opened 1966
Advantages and disadvantagesAdvantages:1) Potential-The planet we live in is mostly ocean2)Quantity-Produces a lot of energy no matter how small the
wave is,3) No visual difference-
Disadvantages :1) Because of the climate conditions it cant work 2)Sometimes a wave can change its size, it can be higher
and depending on the device, this may damage-money3) the energy somehow has to be transported to land or cities
by using an underwater cable. This underground cable is not easy to put and maintain. It is expensive.
Economic impact Implementing energy and tidal waves turbines, is a project that should last
at leat ten year. It will actually cost a lot of money that will come from the government or
the company. Natural disasters or harsh climate conditions can damage the device, the
generator. When this happens companies lose money in a device which nature just
damaged. All of this has big possibilities of happening or not happening, but there are other things that are negative aspects for this energy source application.
Mainly since the energy source can be located either on shore or on the ocean itself, the energy somehow has to be transported to land or cities by using an underwater cable. This underground cable is not easy to put and maintain. It is expensive. Because of this the investment increases in a 20% of the total amount. But the resutls are magnificent because it can provide a hole town with energy and evade other expenses for the government. The consumer will have to pay the same amount of energy as usual as for electicity.
Environmental impactThis energy source interacts with the environment in
a good way because: it doesn’t pollute earth in any step of the process This energy source is not like fossil fuels plants that
produce green house gases, acid rains or global warming
This type of energy source is beneficial to our environment because it’s a way of producing energy for us without damaging our home.
Now a days there are studies been done to determine if the device that is use to generate power affects any kind of fish or the food chain.
Future of the energy sourceIn the future, the coming of the
environmental crisis will make waves and tidal energy one of the most productive renewable sources.
Energy taken from waves and tidal movement will much expensier and everyone would look to have it.
On of the major renewable sources, specially in Ecuador.
ECUADOR-≈MICPA≈ Where? . In Ecuador it isa good idea putting this
turbine technology in any coast of the country. For example,
Esmeraldas, Manabí, Guayas, Machala or Loja are possible habitats in which this plan can be done.
Out of all this places, we think Manabí is the best place because
it has 350 kilometers of costal line which ¼ of it is not developed like the main beaches.
Additionally it has powerful waves that help to harness more energy than other beaches. This space would be great to include the turbines in order to support or even replace the main source of energy in Ecuador that is fossil fuels and rather depend on a renewable source like tidal and waves.
How?
With the help of ≈MICPA ≈ and Ecuadors government.
Why Ecuador? FutureSince Ecuador is a country
which its population is growing at a very fast rate, soon we won´t be able to depend only on fossil fuel (non-renewable) that is the main resource of power for the whole country. This idea of having water turbines in the ocean and replacing or using as an auxiliary resource when fossil fuel are gone or little amount is left, is the best to fulfill Ecuador´s shortly coming future.
Why ≈MICPA≈ Our company should be
chosen over other companies that use different energy sources because our proposal resource is tidal and waves that is an renewable energy which means it would fulfill Ecuador´s energy needs until our grand-grand children are born or even more.
Second, it is little expensive to build water turbine equipment at first, but in long term this last for many decades and operating costs are low and usually come from maintenance making the population develop while they receive lots of energy to progress. Third, the energy is free – no fuel needed, no waste produced of any kind from this company or the water turbines itself.
