why are Electrical Power stations located by the sea?

Answer 1

because the electric comes from salt water

Answer 2

Yes, they use water for cooling, but large lakes also have plenty of water. The real reason is that it provides a place for this generated heat to dissipate without affecting the local ecosystem. Cooling towers add humidity to the air. That kind of human-induced humidity is what is changing Phoenix from a hot dry desert to a hot humid swamp. Raising the temperature of a lake changes what lives in the lake.

Nuclear power stations don't require a continuous supply of bulky fuel, and they don't produce harmful or annoying combustion products, which adds some freedom as to where they can be located.

Answer 3

Not all power stations are near the sea, just the nuclear ones as the pumps are under there, most powerstations use lots of water (cooling towers) or cloud makers as i used to call them the source is usually underground, in the case of nuclear it is the sea.

Answer 4

If it's a nuclear power station, they require a lot of cooling water for the reactors. The sea is the most viable source.

Answer 5

Powerstations by the sea are almost always nuclear. They are located there because they need lots of water for two reasons. Fisrt of all they use sea water to cool the containment ponds which are used to store spent fuel. Secondly, they also use sea water to cool the reactors.

Answer 6

You are right that some HVDC applications use earth as the return path. This is possible because HVDC involves controlled sources. In your example, the North-South circuit involves terminals at the two ends that control the amount of current that can flow in that circuit. Likewise, the terminals at the ends of the East-West circuit control how much current flows in that circuit. The fact that those two circuits happen to share the earth return is irrelevant - current flow is controlled. As a practical matter, most HVDC today is bi-polar, meaning that there are metallic conductors for both polarities of the circuit. It is generally undesirable to circulate current through the earth on a continuous basis because that can accelerate corrosion of underground structures such as piping. However, in case of an emergency in which one of the conductors is unavailable, the system can operate on a monopolar basis with earth return.

Answer 7

They need to cool down their units so that they don't erupt in a massive explosion, or have a nulclear explosion in nuclear plants, and the sea water right there is almost a limitless sourse of water. Lakes can run dry during a drought, but the sea is always there.

Answer 8

if you mean the nuclear power stations its because they use the sea water for cooling the reactors, most of the others are inland.

Answer 9

For Hydro power used to generate the electricity.

Answer 10

if you are talking about dungeness and sellafield power stations. this because they are nuclear and they are connected to pumps under the sea for emergence containment. other power stations are powered by windmills or oil.

Answer 11

Well, people who own land surrounding possible locations of power stations will complain about devaluation of property etc, but the sea can't complain!
