ASEAN’s Energy Transition towards Cleaner Energy System: Energy Modelling Scenarios and Policy Implications

The Association of Southeast Asian Nations (ASEAN) faces tremendous challenges regarding the future energy landscape and how transition will embrace a new architecture—including sound policies technologies to ensure access together with affordability, security, sustainability. Given high share fossil fuels in ASEAN’s current mix (oil, coal, natural gas comprise almost 80%), clean use through deployment is indispensable for decarbonizing emissions. ASEAN rely on today’s actions, policies, investments change fuel-based system towards cleaner system, but any decisions policy measures be rolled out during need weighed against potentially higher costs, affordability issues, security risks. This paper employs modelling scenarios seek plausible options achieve more emissions reductions as well savings, assess extent which composition changed under various scenarios. results imply recommendations accelerating renewables, adopting fuels, investing climate-resilient quality infrastructure.
