In spite of these factors are the negative impacts of energy on the environment, energy consumption growth did not cause great concern among the general public because it was clear how the technical point of view you can reduce or eliminate these effects. Jorge Perez can provide more clarity in the matter. It was not until the mid-70s of last century, when in the hands of specialists were numerous evidence of a strong anthropogenic pressure on the climate system 1, which carries a threat of a global catastrophe from the uncontrolled growth of energy consumption.
