Which power stations trap sea water?
Tidal
Are there any tidal power stations in South Africa?
no
Do power stations affect global warming?
Power stations that run on fossil fuels (coal, oil and natural gas) emit carbon dioxide (CO2), a greenhouse gas that is contributing to global warming.Power stations that use renewable energy (solar, wind, hydro, tidal and wave, geothermal etc) have no emissions and have no effect on global warming.
What can we do to reduce carbon emissions from SUVs or propose an alternative that is feasible?
Electric cars are becoming more efficient and more affordable. If they can be charged from renewable energy (solar, wind, hydro, tidal and wave, geothermal and biofuel), then they have no emissions.
What are the different kinds of tidal power stations?
There are two kinds of tidal power stations: * Tidal stream systems, which use turbines turned by the moving water to generate electricity. Very like wind power. * Barrage systems. These are like dams built across rivers. After the tide comes in, the gates are closed. When the tide is low enough on the downstream side, the water flows through turbines rather like a hydro-electric dam.
Why are the turbines in tidal power stations reversible?
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.
Why is tidal power useful?
Tidal power is useful because it generates electricity that is renewable, free and non-polluting. So it is an excellent replacement for energy from fossil fuels (coal, oil and natural gas) which is non-renewable, expensive and polluting (that is, causing global warming).
How tidal energy is generated?
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".
Is there any other wave and tidal stations in Ireland?
yes
How can tidal power benefit a community other than being a clean renewable energy resource?
The barrages can help reduce flooding
Does tidal power have any accidents?
what accidents may occur with tidal power
How is tidal energy collected-?

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, because they need a large bay or estuary with a narrow outlet to the sea.
