摘要: This study assessed technical potentials for energy efficiency improvement in 2050 a global context. The reference scenario is based on the World Energy Outlook of International Agency 2007 edition and assumptions regarding gross domestic product developments after 2030. In scenario, worldwide final demand almost doubles from 293 EJ 2005 to 571 primary supply increases 439 867 (excluding non-energy use). It estimated that, by exploiting potential sectors, this growth can be limited 8% or 317 473 2050. corresponds demand-side 44% 2050, comparison use. addition, exists improving transformation sector. 2005, as much 33% lost distribution energy. that share reduced 19% by, e.g. fossil-fired power generation (assuming no changes fuel mix generation). Including total would then decrease 10% 393 contributes 55% supply.
