Hydropower is one of the most important sources of alternative energy that has a positive environmental impact, since it has a very low pollution rate.
This energy source is based on the exploitation of the process of converting gravitational potential energy, which resides in a given body of water that flows from a certain height into kinetic energy which climbs over a certain altitude. The kinetic energy is converted through an alternator connected to a turbine and turned into electricity.

Perhaps few people know that even the Romans in the ancient world as well as other people were trying to exploit the power of water and energy in order to use in the mills, for example, and which produced a large amount of kinetic energy. Then in addition to grinding grain, water power was used to irrigate the fields and used in the cleaning of many areas. Following the completion of the hydraulic network, it was possible to exploit the potential of this energy source thanks to the construction of the driving machine built by a paddle wheel that revolved around an axis that over time became more and more advanced.
Over time the plants to exploit the kinetic energy produced by this jet of water became more refined and today hydropower is obtained by using the rivers with the construction of dams that can be constructed in different ways.
The river water is collected by means of pipes which allow the transformation of potential energy into kinetic energy which in turn is converted into electricity by the use of an induction generator and electromagnetism.Energy produced from hydropower plants, pumped or generated can be stored. First, pump water in special tanks to obtain the maximum performance from such an action. Often in such systems the stored energy is then set aside to be used when there is a need for it. As was mentioned before, hydropower is a very viable alternative energy source and has a very positive impact on the environment, it is also renewable and can be made constantly available to man in order to meets his energy needs.Another important fact is that the construction of hydroelectric power involves getting the most from the motion of the waves, but also from the currents of the sea, known as tidal energy.Usually hydropower plants are characterized by the presence of a range of machinery used for the exploitation of the kinetic energy that comes from moving water and are connected to other equipment through which electricity is produced.In our country, hydropower meets approximately 15% of our energy needs of the entire national territory. We hope that we can continue to invest in an area like this that can provide more clean energy that respects the environment, nature and human life.
