Policy makers in US and Europe are searching for viable strategies to produce alternative renewable energies: wind, solar, photovoltaic; geothermal and thè agricultural sectors can become important supplier of renewable energy to represent thè 20% of thè entire supply by 2020. Italy is a country with a large amount of imported energy, despite that, thè exploitation of new source of energy is slowly progressing and more investments are required to face thè energy shortage. In this paper we examine thè evolutive scenarios about production/consumption of thè main renewable energies: wind, solar, biomass and thè new organization required to exploit them conveniently. We conclude by examining some network organization: Grid and IFECO able to achieve thè three goals of thè renewable energy: positive energetic, economie and ecologie balance.
