They are built on flat land because the dams in the power station cannot be tilted.This is because the dam would be tilted and wouldn't be secure to build.
I don't know about hilly areas (many stations are next to dams), but they have to be built where the water flows through the turbines by gravity (i.e., does not have to be pumped).
because the conditions for a hydroelectric power stations in the uk aren't right so only a few can be built.
There are hundreds of hydroelectric power stations in England.
for the passage of flood discharge
A power station that harnesses power from running water.
Hydroelectric power stations certainly have their advantages and disadvantages, as do all forms of electrical generation. Probably the best solution is to use a combination of different means of producing electricity, with hydroelectric stations as part of the mix.
Moving water can be used to generate electricity in hydroelectric power stations.
There is electricity in much of the urban areas of Zambia. Hydro power is provided from the power stations at Kariba North, Victoria Falls and Kafue. Many rural parts of the country run on diesel power stations and many are now coming onto solar power.
hydroelectric power.
Hydroelectric power is created by water falling against a turbine by the force of gravity. If the water doesn't have a high place to fall from, there won't be any power.
No, they can't, they have to be powered up and down over several hours - especially nuclear power stations. This is why hydroelectric power stations are so useful to deal with surges in power demand, they can go from zero to full in seconds - Dinorwig Hydroelectric powerstation is the fastest, taking 12 seconds to go from 0 - 1,320 mw.
i don't now so haaaaaaaaaaaaaaaa
