As operational experience in designing and implementing large-scale, energy-efficient lighting programs using CFLs is being gained through projects sponsored by the World Bank and others in various countries, ESMAP of the World Bank initiated an activity in 2008 to help practitioners benefit from these experiences.

Energy efficiency (EE) is a proven and cost-effective measure to address rapidly increasing global greenhouse gas (GHG) emissions. This report identifies, analyzes, categorizes, and describes the main elements of institutional models and practices that have proved effective in promoting EE investments, particularly in the end-use (industry, buildings, residential) consuming sectors.
