This document discusses bringing energy efficiency to developing countries. It notes that greenhouse gas emissions must be reduced to limit global warming to 2 degrees Celsius. Energy efficiency is one of the "four wedges" needed to transition to a low carbon development path. The document outlines the Sustainable Energy for All initiative's goals of ensuring universal energy access and doubling the global rate of energy efficiency improvement by 2030. It also discusses special issues for developing countries, such as removing fossil fuel subsidies and designing energy systems and buildings to incorporate decentralized renewable energy and energy efficiency standards.
