Renewable energy is the basis of sustainable development, because their use does not affect the natural resources.
Allow to reduce CO2 emissions and at the same time reduce our dependence on fuels fossili.Le renewable energies are not only clean but also are generated from sources that regenerate and therefore are almost limitless.
The main sources of renewable energy are the light of the sun, the force of the wind, marine currents, the heat of the Earth, etc even if a precise classification is very difficult and depends on many factors, not all of a scientific.
The European Union has set for the year 2020 an important goal of reducing emissions to which the individual governments of the Member States are adapting to ensure a sustainable future for generations to come.
