The ten countries that make up the Association of Southeast Asian Nations (ASEAN) are exerting an increasingly important influence on global energy trends. Underpinned by rapid economic and demographic growth, energy demand in the region has more than doubled in the last 25 years, a trend that is set to continue over the period to 2040. Given Southeast Asia's role as a global growth engine, understanding what is shaping energy markets in this vibrant region and the implications for energy security and the environment is vital for policy makers and anyone with a stake in the energy sector.

The International Energy Agency, incollaboration with the Economic Research Institute for ASEAN and East Asia (ERIA), has prepared the Southeast Asia Energy Outlook 2015 in response to a request from ministers at the 7th East Asia Summit Energy in Bali, Indonesia in 2013. Drawing on the latest data, and policy and market developments, this report examines the current status and future prospects for energy markets in the region and their implications for energy security, the environment and economic development.
