The World Economic Forum (WEF) launched the fifth edition of their Energy Transition Index (ETI), ranking 115 economies on how well they are able to balance energy security and access with environmental sustainability and affordability. The report considered both, the current state of the countries’ energy systems as well as their readiness to adapt to future energy needs. Six ASEAN countries came into focus based on their performance in the ETI: Thailand, Singapore, Malaysia, Indonesia, Vietnam and the Philippines. In the case of Thailand, the country improved on all three dimensions of the energy triangle which is made up of security and access, environmental stability, and economic development and growth. Thailand also improved on transition readiness.
