This infographic, "Our Elec-tree-city," illustrates how Indonesia's current reliance on fossil fuels—accounting for 87% of its electricity—directly impacts national development and drives climate change. To address these challenges, the CASE project outlines five strategic pillars for reform: providing long-term investment certainty for renewables, enhancing system flexibility, safeguarding system adequacy, managing the retirement of carbon-intensive assets, and ensuring affordable electricity for all consumers. 

The Kamus Kosakata Transisi Energi (Energy Transition Terminology) is a specialized guidebook developed by the Project Clean, Affordable and Secure Energy (CASE) for Southeast Asia to support journalists, media professionals, and beginners in navigating the complexities of climate change and energy transformation. This resource provides clear definitions and illustrations for critical terminology—ranging from Adaptation and Resilience to technical concepts like AMDAL (Environmental Impact Assessment) and Biofuels—to ensure accurate and informative reporting. By bridging the gap between scientific knowledge and public discourse, the glossary aims to shift the narrative in Southeast Asia toward evidence-based energy transitions and higher climate ambitions in alignment with the Paris Agreement

This ASEAN Energy in 2026 is the latest edition of one of the flagship reports by ACE. Since 2022, the annual ASEAN Energy series analyses the key insights into Southeast Asia's energy landscape each year.

This policy paper provides a comprehensive overview of no-regret uses of hydrogen in Thailand’s energy transition. It outlines global trends in hydrogen development, examines the role of climate-neutral hydrogen in achieving a net-zero future in Thailand, and identifies priority applications for the energy sector where hydrogen can deliver clear and strategic value. The paper also presents policy recommendations to guide Thailand’s hydrogen deployment in the energy sector (power generation, industrial, and transport) in a cost-effective, secure and competitive manner.

The white paper Industrial Transformation in ASEAN: A Cluster-Driven Model for Regional and Global Collaboration examines South-East Asia’s rapid industrial growth while navigating rising energy demand and the energy transition. ASEAN is home to over 670 million people and is the world’s fifth-largest economy. As its economies expand, dependence on fossil fuels, fragmented policies and high financing costs risk undermining energy security, competitiveness and resilience.

This Policy Brief examines recent developments in global and regional LNG markets, with particular attention to Southeast Asia. It analyses the structural drivers of price volatility, including Europe’s increased reliance on LNG, China’s expanding and fluctuating gas demand, and the growing role of the United States as a major LNG supplier.

This study, conducted up to December 1st 2024, addresses the challenges of financing energy efficiency (EE) projects in Indonesia, focusing on perceived high risks, low profitability, and limited awareness of energy savings as a business case. It highlights a lack of market demand for EE, small transaction sizes, and insufficient evaluation capacities among local financial institutions (LFIs) as key barriers. These challenges hinder the implementation of EE measures, which could otherwise reduce electricity demand, save costs, and help achieve Indonesia’s climate commitments. The study’s purpose is to evaluate global and local EE financing mechanisms, identify best practices, and provide actionable recommendations for Indonesia.
