In May 2011, the Intergovernmental Panel on Climate Change (IPCC) presented its report on potential of renewable energy (RE) which emphasizes
significant future role of RE in cutting greenhouse gas (GHG) emissions and powering sustainable development. A global team of technological experts and scientists reviewed over 160 scenarios on the potential of six RE technologies and compiled a report entitled ‘Special Report on Renewable Energy Sources and Climate Change Mitigation’ (SRREN) approved by member countries of IPCC. The present report is a short summary of approximately 1000-page comprehensive assessment done by 120 scientists for the IPCC Working Group III (WGIII).
