ASEAN has set shared target for renewables to form 23% of the energy mix by 2025, and while many will see this as ambitious, the International Renewable Energy Agency (IRENA) and the ASEAN Centre for Energy’s (ACE) 2016 report showed this is achievable with significant potential from solar PV, wind power and geothermal capacity to contribute to the existing renewable power capacity. In order to meet the region’s growing needs for energy supply, transmission and efficiency, the IEA has estimated that US$2.7 trillion investment will be required. ASEAN nations must develop the policy and regulatory frameworks that will facilitate the transition to a lower-carbon future and encourage the international support and active participation of the private sector who are so vital to achieving successful outcomes. Integration and collaboration, meanwhile, are important tools in lowering energy costs, diversifying supply, and tapping into renewable and low carbon energy resources. On 3-5 September 2019, Thailand, as ASEAN Chairman for 2019 will host the ASEAN Energy Business Forum (AEBF) in conjunction with the 37th annual ASEAN Ministers on Energy Meeting (AMEM) at the The Athenee Hotel, Bangkok, Thailand.
