turbines are placed under the sea in areas which have high tidal movement. these turbines are designed to capture the energy produced by the tidal movement and is then transformed into electricity.
The tide moves a huge amount of water twice each day, and harnessing it could provide a great deal of energy - around 20% of Britain's needs.
Although the energy supply is reliable and plentiful, converting it into useful electrical power is not easy.
There are eight main sites around Britain where tidal power stations could usefully be built, including the Severn, Dee, Solway and Humber estuaries. Only around 20 sites in the world have been identified as possible tidal power stations.
A few years ago, "tidal power" meant "tidal barrage".

Tidal energy is harnessed by using underwater turbines that are placed in areas with strong tidal currents. As the tides flow in and out, the turbines rotate and generate electricity. This mechanical energy is then converted into electrical energy through a generator attached to the turbine.

When the tides come in or out the water moves fast through the narrow opening. There you can build a barrage, like a dam, which will allow the water to move in and out. Turbines in the barrage will then spin in the moving water and generate electricity which can be fed into the grid.

∙ 15y agoHi, the tidal power topic is a sub-topic in the GCSE chemistry syllabus as it is all to do with using the earths natural resources. Others include, wind trbines, solar pannels etc. There is no chemistry theory behind tidal power it is just the transfer from kinetic energy to electrical energy.

∙ 11y agoAs the tide rises and falls, there is movement of water.
This movement is harnessed by making it turn an impeller, (or turbine), immersed in the moving water.
The turning of the impeller or turbine blades, is connected to an electric generator by a shaft.
The efficiency is enhanced, by selecting or creating, an area of trapped water, such as in an estuary. The movement of the water can then be forced through a barrage (or dam), creating more power.
There are two tides a day (high water and low water). the height varies over a cycle of about 28 days, caused by the gravitational pull of the moon.

Two ways which energy can be extracted from the ocean?
Two ways to extract energy from the ocean are through wave energy, using the motion of ocean waves to generate electricity through specialized devices, and tidal energy, harnessing the power of tidal movements to turn turbines and create electricity.
How is tidal energy gathered and collected?
Tidal energy is gathered using tidal turbines placed underwater in areas with strong tidal currents. These turbines capture the kinetic energy of the moving water and convert it into electricity through a generator. The electricity generated is then collected and transmitted to the grid for distribution.
Energy from tides can be used to generate power?
Tidal energy is a form of renewable energy that captures the energy from the natural rise and fall of ocean tides to generate electricity. This is typically done using tidal turbines that are placed in locations with strong tidal currents. The movement of the tides turns the turbines, which then generate electricity.
How can people get electricity from sea?
People can get electricity from the sea by harnessing the power of waves, tides, or ocean currents using technologies such as wave energy converters, tidal turbines, or ocean thermal energy conversion systems. These technologies can convert the kinetic or thermal energy of the sea into electricity, providing a renewable and sustainable source of power.
What is the definition of tidal energy?
Tidal energy is a form of renewable energy generated by harnessing the energy from the natural rise and fall of tides in the ocean. This energy is captured using methods like tidal turbines or barrages to produce electricity. Tidal energy is considered a predictable and reliable source of renewable energy.
What are some examples of tidal energy being used?
Tidal energy is being used in various ways, including generating electricity through tidal power plants, supporting marine research with autonomous tidal energy platforms, and powering small-scale devices like buoys and tidal stream turbines. Additionally, some countries have implemented tidal energy technologies to contribute to their renewable energy goals.
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 current uses of tidal energy?
Electricity
What are the advantages of using tidal electricity?
It can be relied on and also it produces electricity reliably. tidal energy is a renewable energy, when compared to solar and wind energy it is more efficient source.
What type of resources can tidal energy be put?
Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity. Tidal energy is a renewable energy source.
When was electricity first produced using tidal energy?
in briton
How can people get electricity from sea?
People can get electricity from the sea by harnessing the power of waves, tides, or ocean currents using technologies such as wave energy converters, tidal turbines, or ocean thermal energy conversion systems. These technologies can convert the kinetic or thermal energy of the sea into electricity, providing a renewable and sustainable source of power.
How long does tidal energy last?
Tidal energy is considered a renewable energy source because the gravitational forces of the moon and sun that create the tides are continuous and predictable. As long as the Earth has these celestial bodies and continues to rotate, tidal energy will persist.
In what ways can you use tidal energy?
Tidal energy has been used in the past to run mills, but now the main way to use it is to generate electricity.
How does tidal energy produce heat and eletricity?
tidal electricity is simply a turbine that runs underwater and when it turns with the ebb tide it creates electricity. Then it carries the electricity through pipes back to land
What are the positive affects tidal energy do for the environment?
tidal energy is good because it is a renewable source that doesn't pollute the environment. It is often used to make electricity.
Who Uses Tidal Energy?
Tidal energy is primarily being used by countries with suitable coastal conditions for tidal power generation, such as the United Kingdom, France, and Canada. Some companies are also investing in tidal energy projects to generate clean electricity for local communities.
