The schematic diagram demonstrates all the steps involved in the generation of hydro-electric power using water in great details.
Overall, there are six different steps in the process which involves natural as well as artificial ones. Moreover, the system is optimally designed to efficiently use water as it can be reused after pumping back to the reservoir.
In the beginning, the water in the sea evaporates due to the heat of the sun. Then, the water vapor accumulates to form clouds which condense back to water and fall down as rain. The rainwater is stored in a reservoir with the help of a high-rise dam.
When the valve of the dam is opened, the water flows downhill to the power station where it rotates the turbine to generate electricity. Afterwards, the water flowing out of the power station is pumped back to the reservoir. Meanwhile, the electricity generated is first transferred to the transformer station via high voltage cables. Finally, the electricity is distributed to end users such as individual homes, factories, hospitals or schools through underground cables.
