摘要: The goal of this study was to develop energy demand scenarios for the update of the Greenpeace Energy [R] evolution scenario. The energy demand scenarios cover energy demand in the period 2005-2050 for ten world regions. Two low energy demand scenarios for energyefficiency improvement have been defined. The first one is based on technical energyefficiency potentials and is called “Technical”. The second scenario is based on more moderate energy savings taking into account implementation constraints in terms of costs and other barriers. This scenario is called “[R] evolution”.
