The turbines in tidal power stations are reversible to optimize energy efficiency. This means they can generate power both when the tide is coming in (flood tide) and when it is going out (ebb tide). By enabling the turbines to rotate in both directions, tidal power stations can capture energy from the tidal flow in both directions, maximizing their overall electricity generation potential.
A simple turbine.
Air is drawn into the engine continuously and compressed by a series of rotating blades. Fuel is sprayed into the combustion chamber and burnt increasing the gas temperature to around 1200C.
The hot high pressure gas expands through a second set of blades mounted on the same shaft as the compressor blades. The energy of the gas is partially expended powering the compressor, but has a residual energy which is either expended as a hot jet (resulting in thrust) or which drives a further independent set of blades to power a propeller or other device.

The Good thing about tidal energy is that is a very clean for of energy. Tidal energy is also renewable. Tidal energy plants could be place along the coast.
Located on the northeast coast of North America, the Bay of Fundy is 400 to 700 feet deep. The bay is 180 miles long and measures 62 miles wide at the mouth.
answ2. The tides are caused by the attraction of gravity.
On the side of the Earth nearest the Moon, the attraction of the Moon lessens the strength of the local perceived gravity field.
On the side of the earth farthest from the Moon, the ocean there sees the gravitational pull of the whole Earth-Moon system, but the effective centre of this system is further away than the real centre of the earth. Thus the gravity field is seen as slightly less and there will be high tides there as well.
When the Sun and the Moon are in alignment with the Earth, (New Moon), we have the strongest gravitational force and the tides are at their maximum height.
When the Sun is on the opposite side of the Earth from the Moon, (Full Moon) then we have a weaker gravitational force, and the high tides are not quite as high as for the New Moon case.
The limitation of tidal energy is that it works only twice a day. This is because it is caused by the gravitational pull of the of the moon and sun.
Another limitation is that, for it to be economical, it needs a large bay or river mouth with a narrow opening to the sea, so that the speed of the water can be harnessed. Suitable areas are not common round the world.
Do they CAUSE pollution? Not really. However, by obstructing the normal tidal flows of sea water, they allow pollutants to accumulate in the tidal basin, preventing the pollutants from flowing back out to sea.

Yes it can be stored but if you have massive ammounts going into the object that's holding the energy then it can only hold for a short ammount of time
A:
When the tide is high. It intakes water. When the tide is low. It releases the water, spinning turbines, therefore creating power.
typical power plant generators produce from 50KVAC to 150KVAC regardless if they are hydro, coal, natural gas, etc.
Tides are caused by the interaction of Earth, the moon, and the sun. Changes in the positions of Earth, the moon, and the sun affect the heights of the tides during a month.
It is clean, free and green. In other words, it uses the heat from deep below the earth to generate electricity that has no carbon dioxide emissions, which are harmful to the earth and are causing global warming.
Geothermal energy, and green technologies like it, are important because they are low-risk, low-impact energy sources for us to use without polluting the environment. Geothermal Technology is better for the environment and your home. There are many advantages of Geothermal Technology. The underground loop carry warranties of 25 to 50 years! According to the U.S. Department of Energy, if just 100,000 homes converted to a geothermal heating and cooling system, carbon dioxide emissions could be reduced by 880 million pounds.
Tidal power produces electricity, the same electricity that you use in everyday life.
Some countries are planning systems that will use the tides as a source of renewable energy. That is an extremely good idea.
It, depends on if you mean is it expensive to start up or to run, because once you have started the tidal energy up, it is free to run (costs no money to run)
Following advantages of high tides may be considered on priority.
1. It helps in navigation.
2. It is also helpful for producing more tidal energy to wider variation in wave guides amplitudes.
3. It also help for fishing, since more fish and prawns come at sea sore.
4. More items from sea like shells etc come out at sea sore during high tides which is advantageous to local business community.

it is caused by the shocks of an earthquake and the earthquake is caused by the movements of the plates at the bottom of the earth
