The diagram shows a simplified overall process for hydroelectric power generation.
The process starts by utilizing natural resources, mainly seawater, which undergo constant evaporation through exposure to natural sunlight. This will eventually form rows of clouds that move and eventually precipitate as rainfall.
Massive amounts of rainfall are then collected into dedicated reservoirs with specially designed dams constructed around it. Pipes are then connected from those reservoirs into hydroelectric power plants, specifically designed to utilize gravity to create water flow into hydroelectric turbines.
Immense water flow will force the hydroelectric turbines to spin and thus generate hydrokinetic energy. This energy is later converted into electric energy, which runs through high-power cables and into transformer units. The number of transformer units inside multiple transformer stations are connected to cables that run underground.
These cables are responsible for the redistribution of the hydroelectric power received from the transformer units to worst population centers and public facilities.
