This synthesis of the energy issues discussed in the national reports of Rio+20 are intended to help strengthen implementation of the Rio+20 directions and commitments. The report identifies lessons and best practices across all regions, underscoring the nexus of energy-related concerns with other sustainable development factors. It addresses in particular the issues relating most directly to the three focal areas of the UN Secretary-General's Sustainable Energy for All initiative: access to energy services, improving energy efficiency, and increasing the use of renewable energy sources.
