Das Projekt "Global Energy Scenario - Energy Revolution Update 2008" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt, Institut für Technische Thermodynamik, Abteilung Systemanalyse und Technikbewertung durchgeführt. The project develops an update of the Energy Revolution scenario developed in 2006 (see www.energyblueprint.info). The Energy Revolution scenario is a global energy scenario based on the assessment of energy demand and supply patterns and the renewable energy potentials available in ten world regions. The normative scenario is developed in a back-casting process, driven by ambitious CO2-reduction targets and the world-wide phasing-out of nuclear energy. The project develops energy demand projections based on key macroeconomic indicators, and elaborates supply scenarios for the heat and electricity sector. The mobilisation of renewable energy technologies takes into account their respective technical potentials, actual costs, cost reduction potentials, and technology maturity. The time horizon of the scenarios is until the year 2050. Scenario development includes in-depth discussions with counterparts from the ten world regions on specific regional energy policy framing conditions, and with the renewable energy industry on the expected market development in the different technology branches. The update of the Energy Revolution Scenario will take into account the most recent trends in global energy demand and supply and CO2 emissions. Compared to the previous version, it will provide a more detailed assessment of the transportation sector.
