The diagram illustrates the generation of electricity by water power.
This difficult process includes technical cycle and natural water circulation as well.
Firstly, water after evaporation falls in rain form into the dam reservoir which is controlled by valve.
When the valve is opened, water goes through the turbine that generate water power to electricity.
From the turbine water flows to the pump and returns to the reservoir.
Electricity coming from the turbine goes through high voltage cables to transformer station.
Finally, electricity inputs into houses and buildings through underground cables.
To conclude, hydro-electric power generation is a multi step process which requires both technical and natural resources.
Additionally, hydro-electric generation is ecologically friendly process using renewable natural resource.
