Carbon-Free Electricity in G20 Countries
Status and the way forward In 2024, the Republic of Korea proposed the Carbon-Free Energy (CFE) Initiative to promote the use of technology-neutral, carbon-free energy to decarbonise the energy sector.In line with this initiative, Korea’s Ministry of Trade, Industry and Energy (MOTIE) commissioned this report to analyse the status and prospects of carbon-free energy in the electricity sector in G20 countries, and to provide policy recommendations to advance its progress.The International Energy Agency (IEA) and the Korea Energy Economics Institute (KEEi) jointly produced this report.

Southeast Asia Indicators Handbook for Just and Inclusive Transitions
Energy demand in Southeast Asia is growing, driven by rapidly growing population and economies, industrialisation and urbanisation. Many countries in the region have set out their own national decarbonisation targets and clean energy transitions commitments.Clean energy transitions in the region present unique opportunities to deliver broad socio-economic benefits, beyond emissions reductions, such as the creation of new decent jobs, economic diversification, reduced energy poverty and improved air quality. Tracking these benefits can help ensure that all parts of society benefit from these changes.In 2024, G20 leaders endorsed ten voluntary G20 Principles for Just and Inclusive Energy Transitions…

Energy and AI in East Asia
This report was commissioned by the Korea Energy Economics Institute and was carried out jointly by the International Energy Agency (IEA) and the Korea Energy Economics Institute. The study has three objectives in the context of East Asia. First is to explore the possibilities presented by AI for the energy sector. Second is to examine the expected increase in electricity demand by data centres, and the impact on grid planning and operation. Third is to provide policy recommendations for embracing the opportunities presented by the application of AI to energy, as well as policies for proactively managing the challenges presented by…

Integrating Solar and Wind in Southeast Asia
…However, integrating higher shares of VRE can present technical and regulatory challenges that require changes to system operation and planning. This report provides a comprehensive assessment of the readiness of Southeast Asia’s power sector to integrate higher shares of VRE - identifying opportunities and key considerations. It reviews technical and regulatory measures that are being implemented and applies the IEA’s six-phases of VRE integration framework to assess potential challenges within the context of each country’s power system. Drawing on this assessment, the report outlines practical actions for policymakers, regulators, utilities and regional entities from 2025 to beyond…

Asset values
…This is often known as a “split incentive.” However, evidence from the United States suggests that energy efficiency improvements are associated with reduced vacancy and tenant turnover, which reduces associated transaction costs and provide an incentive for landlords to invest.

Energy savings
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy savings. Why is energy efficiency important for energy savings? Energy efficiency measures reduce the amount of energy required to fuel and grow our economies. In economies where energy demand is set to grow significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors…

Grid investments
…on grid infrastructure. Demand response has seen rising uptake around the world, but further electrification and demand decarbonisation are expected to significantly increase its importance. For instance, in Australia, where various mechanisms have been successfully demonstrated, the value of demand response capacity could reach USD 11 billion per year by 2042. Globally, it could provide up to 50% of short-term flexibility needs in 2050. Need more information?

Responding to Satellite Notifications from the Methane Alert and Response System
…Nations Environment Programme’s (UNEP) International Methane Emissions Observatory (IMEO) introduced the Methane Alert and Response System (MARS), which uses satellite data (coupled with scientific expertise and artificial intelligence) to provide free notifications of large methane emission events to governments and companies.MARS satellite alerts provide rapid and actionable information that can enable quick mitigation action. Swift action on major leaks or releases detected via MARS can deliver significant benefits for governments, potentially reducing gas waste, boosting sales by domestic companies and improving national energy security while simultaneously decreasing air pollution, minimising local health impacts and increasing productivity. More broadly…

Portugal 2026
…Review was prepared in partnership between the Government of Portugal and the IEA. It draws on the IEA’s extensive knowledge and the inputs of expert peers from IEA Member countries to assess Portugal’s most pressing energy sector challenges and provide recommendations on how to address them, backed by international best practices. The report also highlights areas where Portugal's leadership can serve as an example in promoting secure and clean energy transitions. It also promotes the exchange of best practices among countries to foster learning, build consensus and strengthen political will for a sustainable and affordable energy future.

Policy Toolbox for Industrial Decarbonisation
…Policy Toolbox is divided into three broad areas with nine categories in total that group policy instruments according to their objectives. These broad areas are: Framework fundamentals, including (1) Establishing plans and policies for long-term GHG emissions reductions and (2) Mobilising finance and investment; Targeted actions for specific technologies and strategies, including (3) Managing existing assets and near-term investment, (4) Creating a market for near-zero emissions materials production, (5) Developing technologies, and (6) Accelerating material efficiency and circularity; and Necessary enabling conditions, including (7) International co-operation and a level playing field, (8) Infrastructure planning and development…
