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.

What is it called when you have extra high tides and extra low tides?
Spring tides, tidal surges.
Tidal power how the energy source is turned into usable energy?
Tidal power harnesses the energy from the movement of ocean tides to generate electricity. This is typically done using underwater turbines that spin as the tides flow in and out, converting the kinetic energy of the tides into mechanical energy which is then converted into electricity through a generator. This electricity can then be transmitted to the grid for use by consumers.
What are the largest tidal movements called?
The largest tidal movements are called spring tides. Spring tides occur when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides.
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.
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 far apart are high tides in a typical tidal cycle?
High tides are typically about 12 hours and 25 minutes apart in a typical tidal cycle.
What does a tidal generating station require to be 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 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.
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
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 .

Why does the solent have four high tides per day?
The Solent experiences four high tides per day due to its unique geographical features and the interaction of tidal forces. These forces create a complex tidal pattern that results in two high and two low tides occurring approximately every 6 hours. The shape and orientation of the Solent play a key role in amplifying these tidal effects.
