Hydropower

Electricity is one of the infrastructures needed to develop a nation. Electricity can be produced from many kinds of resources, such as gas, coal, oil, wind and water. The electricity generated from a turbine ( =engine) and generator turned by flowing water is called hydropower.


Hydropower is a clean, renewable and affordable (= cheap for most people) energy because of the water cycle- the continuous movement of water that includes evaporation, condensation and precipitation, which means that the water supply for electricity generation (= production) can be refilled by rain.


Hydropower generation can also prevent floods because dams are built on rivers to store water.
