Writing Feedback / Hydro-electric power generation [3]
Hydro-electric power has become very familiar in our life today. Let's find out where it comes from and how it is produced.
Hydro-electricity comes from water, an unexhausted natural resource. Water from the sea is heated by the sun and evaporates up to the sky, where it meets cold air making it turn into clouds, then falls down to the earth through the rain. A part of water from the rain drops down into reservoirs where people build many dams to keep it in for the purpose of creating electricity which we call hydro-electricity. Hydro-electricity is producing by letting water flow through a turbine, which changes water power into electric power. Water after going through the turbine will be returned back to the reservoir by a pump, while the electric power is carried up to high voltage cables, then to a transformer station to transform it from high voltage to the voltages lower, appropriate to many different using purposes. After that, the underground cables will supply these electric currents to assuming places, such as factories, hospitals, schools or each household.
Although in today's world, people have been finding more methods of creating electricity, we can't deny that hydro-electric power is still very important because of its available, unlimited resource and incomplex producing method in the comparison with the other electric power such as thermo-electricity or nuclear-electricity.
