Water and energy

In addition, water is a renewable source of energy: the production of energy in hydroelectric plants does not involve real water consumption, but reduces the availability of water in other sectors (such as farming or civil sectors).
Water is also used in thermoelectric plants, where it is not directly used to produce energy, but only to cool machinery. Water from industrial uses can also be polluted, even if now many industrialised countries have issued strict laws that limit the concentration of pollutants in waste water, obliging the companies to send it first to special depurators that remarkably reduce its pollutants and send it back to lakes, rivers and seas when they are compatible with.
