Renewable Energy Developments and Potential for the Greater Mekong Subregion This report was produced under the technical assistance project Promoting Renewable Energy, Clean Fuels, and Energy Efficiency in the Greater Mekong Subregion (TA 7679). It focused on renewable energy developments and potential in five countries in the Greater Mekong Subregion (GMS): Cambodia, the Lao People’s Democratic Republic, Myanmar, Thailand, and Viet Nam. It assessed the potential of solar, wind, biomass, and biogas as sources of renewable energy. Technical considerations include the degree and SUBREGION MEKONG IN THE GREATER AND POTENTIAL DEVELOPMENTS ENERGY RENEWABLE intensity of solar irradiation, average wind speeds, backup capacity of grid systems, availability and quality of agricultural land for biofuel crops, and animal manure concentrations for biogas digester systems. Most GMS governments have established plans for reaching these targets and have implemented policy, regulatory, and program measures to boost solar, wind, biomass, and biogas forms of renewable energy. Incentives for private sector investment in renewable energy are increasingly emphasized. About the Asian Development Bank ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to the majority of the world’s poor. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. Based in Manila, ADB is owned by 67 members, including 48 from the region. Its main instruments for helping its developing member countries are policy dialogue, loans, equity investments, guarantees, grants, and technical assistance.
