The provided diagram illustrates the stages of electricity production by means of a hydro-electric power plant.
Overall, the whole process consists of five main stages namely, evaporation and rain, reservation of water, electricity generation, and power distribution.
The process begins with evaporation of water by rays of sun, which then transforms into storm clouds and rains. The water of rain is stored in reservoir dam. When the drain valve opens, the stored water flows by force into a turbine chamber, that results in electricity production and gets pumped back into the reservoir. After this stage, the electricity generated by turbine is transferred into transformation station using high voltage cables. In this station the voltage of the electricity is lowered, before it is distributed among houses, factories, and public services like schools and hospitals, through the use of underground cables.
