Day by day, to Satisfy their energy needs, industrial societies pollute our environment. Around 90% of the world’s fossil fuel production is yearly extracted from the subsoil. In 1989, 3.5 billion tons of coal,3.1 billion tons of oil and 1.4 billion tons of gas were extracted. The transport of fuels accounts for around half of the maritime traffic. A significant proportion of the eight billion tons/year flow of fossil fuels is burned, and the combustion products are discharged untreated into the environment, mainly into the atmosphere. The challenge of producing the energy needed to satisfy world consumption without depleting resources and damaging the planet’s environment. However, it is necessary to focus on renewable energy solutions: wind power, solar energy power biomass and other renewable energy. nevertheless, the current share of this promising new form of energy in global products is around 15%.
