Energy efficiency may be named as energy consumption decrease keeping same energy services, without reducing comfort and quality of life, protecting environment, guaranteeing supply plus proping-up a sustainable behaviour in its use.
Moreover, Renewable Energy, is deemed nowadays as alternative to so called conventional energies even though they are not new energies. Its use has been widely spread until alternative energy sources arrival, so presently we want to abolish, such as petroleum, and this contributed to its withdrawal. It represents 20% consumed energy and is also called soft or clean energies being its most meaningful advantage its respect towards environment.
Its main advantages: no waste generation difficult to remove so considered “clean”; its environment impact reduced, for no CO2 emissions nor other atmosphere polluting gases; produced in continous form so unlimited; they self-generate, avoiding interregional dependence as well as policy conflicts fuel supply derived; they are complementary; balancing interterritory maladjustments and driving local economies 5 times more than conventional ones via job creation.
Energy efficiency and renewables has gained an ever increasing importance to achieve energy policy targets: supply guarantee, competition and environment respect. Energy efficiency priority and strategy character plus renewable energies plus national targets compliance medium and long term require new rules that complete, integrate and improve present legal frame, giving stability to energy efficiency boost plus renewable energy development.
