Why don't we use the motion of waves in the oceans to generate electricty?

Answer 1

We do

Answer 2

Why don't you market that idea and make a billion dollars! That's a good plan... kind of like solar.
I suppose the main problem is getting the electricity generate by those "wave turbines" back to main land so it can be stored. A huge network of cables would probably be expensive, and more difficult than coal or nuclear. Remember, power companies are like any other company...out to make moola $$$.

Answer 3

This is being carried out or experimented with in some countries. Unfortunately, the amount of electricity generated from renewable sources such as waves, tides, wind, and solar energy make a tiny part of the total amount of electricity produced and consumed by these countries. Electricity generation from renewable sources frequently runs into problems with planning permissions and the public's objections to having their view of the sea or a field ruined by a bunch of wind turbines. Fishermen also object to wave or tidal generators as their use would mean that they would not be able to fish in certain areas (as their nets would get entangled within the generators' mechanisms). Also, companies that specialise in production of fossil- or nuclear-fuelled power stations frequently influence governments' decisions on power generation through their financial power.

There are also technical and cost problems with many forms of electricity generation through renewable sources. For example, to produce electricity with waves in the sea/ocean, the generators would have to be installed far away from the shore and the generated electricity would have to be transmitted (through cables), for some distance, before it reaches land, where it can then be distributed. The generators will also have to be built to be very sturdy to withstand strong storms. All of this adds to the cost of electricity produced.

Humanity has the means for producing clean energy to save itself and the Earth from climatic chaos. But the higher cost of clean electricity and humanity's selfish behavior (in trying to have a nicer view, the ability to net more fish, or make greater financial gains) prohibits it from doing so. Unfortunately, it is unlikely that clean electricity will overtake more traditional and polluting sources of electric power in the near future. For the short-term, we should be concentrating on energy efficiency (e.g. installing better insulation, using energy efficient light bulbs, and switching off equipment that are not being used) and try to reduce our reliance on mains supplied electricity by installing our own sources of clean energy for use at home (e.g. solar panels and wind turbines). Controlling population growth is also an important (if not the main) solution to the problem. The more of us there are, the more energy will be needed. We cannot solve the problem by waiting for someone else to come up with a solution for us. Be more energy efficient (and have less children).

Answer 4

Some places do use this though its usually not cheap then the power in the lines. The initial cost (investment) is typically to high for a reason rate of return. This has been explored many times if you have a good system in mind and the investor(s) for it, it can be done.

Answer 5

The waves push a set up windmill, making it spin, the spinning result creates friction adversarial to some thing, generating electricity. Then the electricity is kept and in a position to apply for some thing.

Answer 6

We can use it.But it involves lot of controls over it.Because the motion of waves are not uniform.The speed and attitude were varying from time to time.
The force exerted from the waves are small compared to other systems and cost involved also high .These things are major constraints for this.

Answer 7

I don't think it's powerful enough in a small space. It would take years to make a profit with all the equipment it would take to construct a plant. Your question is one I would call...

Una pregunta excelente

Answer 8

We can, and some places do.

Answer 9

it's not economical & the efficiency of electrical produce did not outpace other type of power plant (eg hydroelectric).

Answer 10

You've never heard of hydroelectric power?

Answer 11

They are already doing that in britain
