The diagram illustrates how generical city processes water in order to product electrical power.
Everything starts from the sea, which water evaporates because of the heath of sun. Secondly, evaporated water creates clouds and then these produce rain. Consequently, when it rains, the water is accounted in big reservoirs, which are closed from a valve. When this one is opened, water starts moving very fastly because of gravity force, and reaches a turbine with high energetic energy and, thanks to this movement, a big amount of energy is transformed into mechanical power.
At this stage of the process, this hydro-electrical energy is transported to a transformer station with high voltage cables.
In the end, this essential energy is taken to houses, factories, hospital and schools with few underground cables and it is used in our daily routines.
