5.5: Pumped Storage Hydroelectric Plants (PSHP)
One great advantage of hydropower technology is that it makes it possible to build plants in which large amount of energy can be stored and used later "on demand". Such complexes are called "pumped storage plants".
Hydraulic energy: what it is, how it works and its advantages
Clean and sustainable energy: hydraulic energy does not generate polluting waste, it uses a renewable energy source and greatly reduces CO2 emissions. Very safe : it can be said that hydroelectric power plants use water as their "fuel" to generate electricity, this makes them very safe compared to other types of power stations.
