Is it true that tidal energy can be used only near an island where tides are very high and very low?

Tidal power comes in two flavours - tidal range, which uses the difference in height of the tide between high tide and low tide, and tidal stream, which uses the speed of the tidal water as it moves round the coast. Tidal stream power extraction is most often found near islands and headlands where the flow is funneled between landmasses. This accelerates the flow, giving areas of high energy that can be extracted.
Most tidal stream devices are more suited to these areas of high energy, however companies such as Minesto are concentrating on areas of lower energy, which are far more common and widespread.
So to answer your question - most devices need the high flows found near islands and headlands, but there are one or two that don't.

How is tidal energy effective?
Tidal energy can work in only certain locations. A tidal generating station must be in an area where the difference between high and low tides is very large. This means the tidal waters will have a great deal of energy.
What is it called when you have extra high tides and extra low tides?
Spring tides, tidal surges.
Where is tidal energy obtained from?
Tidal power operates by damming the mouth of a river or other water source that leads into the ocean. When the tides come in (tides are created by the gravitational pull of the moon) the dam lets water flow through. At the peak of high tide the dam is closed until the peak of low tide. Then the dam is opened and turbines are powered by the water flowing out into the ocean due to the water level difference. To learn more about how tidal power works check the related link.
How is tidal energy?
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
What is the difference in height between successive high and low tides called?
tidal range

Where is Tidal Energy found on Earth?
There is a large tidal energy scheme at Rance in northern France. There are smaller ones in other parts of the world. Tidal mills were once fairly common in Britain. Tides are caused by the gravitational forces of the moon. These forces translate into high and low tides, on the earth. Tidal energy is transferred from the moon to the earth by tidal torque. This results in tidal lock. This is why you always see the same side of the moon
What does a tidal generating station require to be effective?

What occurs when high tides are the highest and low tides are the lowest?
Tidal maximums and Tidal minimums. These two Incidents are not co-incidental.

Why is tidal energy not likely to be potential source of energy?
harnessing of tidal energy poses many problems . the rise and fall of water during tides is not high enough to generate electricity on a large scale . there are a very few sites that are suitable to build dams .

What is the difference in height between successive high and low tides called?
tidal range
What tide forms when water is drawn away from the area between high tides?
Tidal pools are formed when water is drawn away from an area between high tides.
What are the world-wide typical tidal variation between low and high tides?
