Hydroelectric power plants.
In a hydroelectric power plant, the functioning is basically the same as in the other power plants we have seen so far: kinetic energy-turbine-transformer.
But in the case of the hydroelectric power plants, kinetic energy is produced by the natural movement of the water stored in a reservoir.
In Spain, the hydroelectric energy production is very limited. It only covers 15% of the electric consumption (that is, 2,6% of the total energy consumption).
