    A new report released by the International Institute for Applied Systems Analysis (IIASA), during the UN Conference on Sustainable Development (RIO+20), outlines 60 alternative sustainable energy pathways.

    The Global Energy Assessment (GEA) involved specialists from a wide range of disciplines interconnecting with energy themes: more than 500 scientists, policymakers, industry specialists, and energy experts, from 70 countries.

    This study detects 41 of them which offer viable, cost effective choices for policy and that simultaneously satisfy the following criteria: universal access to affordable energy, enhanced energy security at local and national level, attenuation of climatic change due to rising temperature, better human and environmental condition of health.

    The challenge requires an effective change of energy system, addressing  policy makers to achieve sustainability goals by 2050.

    Following the implementation of the EU Directive on Energy Efficiency could be obtained some important results in the sector.

    These changeover need strong investment in new energy infrastructure, improvements in efficiency, particularly in building and transport, transition from fossil-fuel based energy systems at others based on renewable energy sources.

    It would require an increase in annual investments from present levels of approximately $ 1.3 trillion (more than €1 trillion)  to $ 1.7 trillion (€1,35 trillion), about two percent of current world Gross Domestic Product (World GDP).

    However co-benefits will balance the up-front investments needed: energy efficiency, renewables, synthetic transportation fuels, cooking fuels, electricity with Carbon Capture and Sequestration (CCS), support goals related to economic growth, jobs, energy security,  health, climatic and environmental benefits.
