The diagram outlines the principal stages involved in hydro-electric power generation. This process has its origins in the natural water cycle and concludes with power being provided to relevant infrastructure.
At first, solar energy heats water in the ocean, causing it to evaporate. As the water vapour rises, it condenses and forms into clouds which move over the land. Eventually, the clouds will drop rain, some of which will fall into a reservoir. The water stored in this area is kept back by a dam, which contains a valve to open and close it. When the valve is released, water flows down a steep incline and its momentum spins a turbine, producing power. At this point, most of the power is transferred through high-voltage lines to a transformer station, which converts the power into a voltage that is suitable for the electricity needs of the local area.
Finally, it is important to state that some of the surplus power generated by the turbine is used to pump the water back up into the reservoir so that it can be used to meet electricity demands in the future.
