The GEA is the first ever fully integrated energy assessment to analyze energy challenges, opportunities, and strategies, for the world’s economies. Conducted by 500 of the world’s leading energy experts in research, academia, business, industry, and policy from the developing and developed world, the GEA is supported by government and nongovernmental organizations, the UN system, and the private sector. The GEA clusters around four topics that are key to the current, much-needed energy transformation: review of major 21st
century energy challenges; assessment of current energy technologies; options and pathways to solutions; and policy recommendations and tools to achieve goals. The scientific assessment, writing, and peer review took five years and results were published in a 1882-page book in 2012.
The GEA database includes detailed quantitative information for 41 pathways to sustainability. Six GEA scenarios meet the three SEforALL objectives: i) providing universal access to modern energy services, ii) doubling the global rate of improvement in energy efficiency, and iii) doubling the share of renewable energy in the global energy mix. These six scenarios underpin all SEforALL scientific work. As Kandeh Yumkella, founder of SEforALL, says: “The IIASA Global Energy Assessment served as both the scientific basis for SEforALL, and the inspiration behind our aims.”
Work for the GEF has centered on the development of GEA scenarios, coordinated by IIASA researcher Keywan Riahi. Moreover, 42 GEA authors contributed to IPCC Fifth Assessment Report, published in 2014.
