Re: Use Less Electrical Energy.
Hydro electric does work and if like up here you dont know they are there. There is a small Hydro electric powerstation above Loch Earn and the only clue is the out flow at St Fillins as the main body is well hidden.
Power Stations
Hydroelectric Power.
A large river which falls down a steep slope
is suitable for generating hydroelectric power.
The river is dammed at the top and the valley is flooded
creating a large reservoir (lake) of water.
The water is let out through turbines at the bottom of the dam.
The turbines turn a generator which produces electricity.
The original source of the energy is the Sun
which makes the wind blow and the rain fall.
Gravity causes the falling water to turn the turbines.
Advantages of hydroelectric power.
1. It is renewable.
2. It is readily available.
If you need more energy,
you just let out more water through the turbines.
3. It does not cause pollution.
Disadvantages.
1. Flooding the river valley will destroy the local habitat
for many of the species which live there.
