The diagram describes the production process of hydro-electric energy. It is important to note that natures are involved in the early process, while the latter roles are taken by mechanics. In conceptual, mechanical energies are converted into electrical energy.
Firstly, water in the sea are heated by the sun before being evaporated and transformed to cloud. Due to low pressure, which temperature follows the same, the cloud condenses and becomes rain. Then the rain will be stored in a reservoir surrounded by a dam, which its flowrate is set by the valve. The mechanical energy is begun when the valve is opened and then the water flows to the path to turn on the turbine. Following this, the water are pumped to reservoir again and will be re-circulated.
The change of energy happens since the turbine is rotated. Its mechanical energies are converted into electrical energies, then are delivered through high voltage cables and stored in transformer station. Next, electrical energy will be transported to consumer such as industrial/residential area using underground cables.
