RENEWABLE ENERGIES
RENEWABLE ENERGIES AND CLEAN TECHNOLOGIES
Those energy sources are based on the use of natural resources: sun, wind, water or biomass of plant or animal origin. They are characterized by not using fossil fuels, but natural resources capable of unlimited renewal. Renewable energies are known as alternative energies or green energies.
Clean technologies are those technological practices that try to minimize the environmental impact that is normally generated in all human activity.
