Hydroelectricity-what is it?

Mobile phones, cars and washing machines. What do all of these have in common? They run on electricity. Electricity obviously plays a big role in our lives, making it easier and helping us with our advanced home appliances. As well as home appliances, electricity also enables us to use the devices of the 21st century. As you can see, electricty enables us to use and do a lot of things. Without it, we wouldn't be able to use modern devices and our lives would be much more complex.

The word 'hydro'. What does it mean? The word hydro means of, pertaining to, or furnishing water. In this case, 'hydro' is the root word in 'hydroelectricity'. Therefore, hydroelectricity is electricity- electricity produced from water.

How does a hydroelectric power station work?

Hydroelectricity is created via falling water.

The water that is stored from reservoirs flow throught the penstocks that are connected to the reservoir as well as the power station. The water then triggers a hydraulic turbine, which then turns a generator, thus producing electricity.

After this process, the water is then directed to an exit that is called a 'tailrace'. Next, the water goes back to the river below the dam as it returns to its natural detination.
