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.
The coastline has to be suitable, for example a large bay with a narrow outlet to the sea. Some kind of barrage or dam is erected there which will allow the incoming tide to fill the bay. 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.
First, tides ebb and flow spinning turbines underwater. Since the turbines are on top of a gearbox shaft, it spins fast enough to create electricity. Then the electricity is carried out by cables and into your house
Hi, 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.
As 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.
the waves of the tides create such force that scientists have created wave machines, and they put water in these machines to create the force of the waves, and that is how they create the electricity.
Energy cannot be created or destroyed, only changed from one form to another. The moving water of a tide possesses kinetic energy. This can be used to turn the turbines of a power station, which move the generator to produce electricity.

What does tidal energy mean?
Tidal energy is a form of renewable energy that harnesses the power of tides to generate electricity. It works by using the kinetic energy of the moving water, such as tidal currents or the rise and fall of the tides, to turn turbines or other devices that generate electricity.
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.
What is the parts of tidal electricity?
Tidal electricity generation typically involves three main components: tidal barrages, tidal turbines, and tidal fences. Tidal barrages use a dam-like structure to capture and release water to generate electricity. Tidal turbines are similar to wind turbines but operate under the water to harness tidal currents. Tidal fences are long barriers that contain turbines to capture energy from tidal flow.
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.
Where the energy comes tidal energy?
Tidal energy is created by the gravitational forces of the moon and sun on the Earth's oceans, causing tides to rise and fall. This movement of water generates kinetic energy that can be harnessed and converted into electricity using tidal energy technologies such as tidal turbines or barrages.

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.
What two ways can tidal energy be used?
Tidal energy can be used to generate electricity through tidal stream systems, which harness the kinetic energy of moving water, or through tidal barrage systems, which use the potential energy of changing water levels to turn turbines and generate power.
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.
How does tidal energy produce heat and eletricity?
Tidal energy is harnessed using tidal turbines or tidal barrages that capture the energy of moving water as tides come in and go out. This movement drives generators to produce electricity. The process of converting kinetic energy of the moving water into mechanical power and then electrical energy does generate some heat as a byproduct, but the primary output is electricity.
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.
How much electricity does tidal energy make in a day?
The amount of electricity generated by tidal energy in a day can vary depending on the location and specific tidal energy technology being used. On average, tidal energy projects can generate anywhere from a few megawatt-hours to tens of megawatt-hours per day.
