Generally uses hydroelectric power potential of waterthat comes from natural causes from a falling slope that passes through a hydraulic turbine which transmits power to a generator turning it into hydroelectric power. Some forms of work is through areservoir, where water reserve and then use the aforementioned method.
The ancient Romans and Greeks took advantage of the energy and water, hydraulic wheels used to grind wheat. During the Middle Ages,large wooden wheel hydraulic develops a maximum of fifty horses. Hydroelectricity was very important during the Industrial Revolution. Hydro helped the growth of new industrial cities were created inEurope and America until the construction of canals in the mid XIX.
Projects powerful dams can cause irreversible environmental changes in a very large geographical area, therefore, have thepotential to cause significant impacts. Environmental and social costs can be avoided or reduced to an acceptable level, if carefully evaluate potential problems and corrective measures are implementedthat are expensive. The catchment area of a dam extends from the upper limits of the reservoir to the estuaries and coastal areas and offshore, and include the reservoir, dam and river basin. Theindirect effects of the dam include those associated with the construction, maintenance and operation of the dam.
The benefit of the hydroelectric project is the electric power, it can support economicdevelopment and improve quality of life in the area served. Hydroelectric projects require much labor and so offer a variety of employment opportunities. In addition, the generation of hydroelectricpower provides an alternative to burning fossil fuels or nuclear energy, which can meet energy demand without producing hot water, air emissions, ash, radioactive waste and CO2 emissions
