Hydroelectric Power Stations

What is the process of making energy in a Hydroelectrical Power Station?

A Hydroelectric Power Station is a power station that generates its energy by the movement of water. The water is then rotated in a turbine shaft that is connected to a energy genorator. The generator alters the energy of the movement of the water to electricity which is transferred to our homes by wires, linked to our homes.


What is an advantage of an Hydroelectric Power Station?

One advantage of a Hydroelectrical Power Station is that it does not produce any green house gases and so does not pollute our atmosphere. If electricity is not necessary than the sluice gates may be closed to stop the generation of electricity. The lake that is formed behind the dam can be used for other purposes.


What is a disadvantage of an Hydroelectric Power Station?

The dams are very expensive to build and need to be of high standard. If the dam does flood over than the people living nearby need to evacuate out their houses. This means that their homes will be destroyed. Although large dams can cause major geological problems like the one in the USA. The Hoover Dam caused many earthquakes.
