Construction Of Mini Hydroelectric Projects At Home
Hydroelectric power, or hydroelectricity, is renewable electrical energy that comes from the conversion of hydropower into electricity.
The kinetic energy of the water current, natural or generated by the difference in level, is transformed into mechanical energy by a hydraulic turbine, then into electrical energy by a synchronous electrical generator.
In 2020, the installed capacity of hydroelectric power plants reached 1,330 GW, producing approximately 4,370 TWh, or 70% of global renewable energy production and 15.6% of global electricity production in 2019.
The advantages of hydroelectricity are its renewable character, its low operating cost and its low greenhouse gas emissions; the storage capacity of its reservoirs contributes to offsetting variations in demand as well as those of intermittent energies (wind, solar).
However, it has social and environmental impacts, particularly in the case of dams located in non-mountainous regions: population displacements, possible flooding of arable land, fragmentation and modifications of aquatic and terrestrial ecosystems, blockage of alluvial deposits, etc.
The main producers of hydroelectricity in 2020 are China (31.0%), Brazil (9.4%), Canada (8.8%) and the United States (6.7%), whose plants are among the most powerful.
