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.

Sustainable Transport Policy for Armenia: A Roadmap
As a part of the EU4Energy Programme, the Armenia Energy Policy Roadmap on Sustainable Transport presents a comprehensive, evidence-based framework for transforming the country’s mobility system into a sustainable and efficient transport system. The strategy seeks to deliver significant reductions in CO₂ emissions while strengthening regional connectivity, fostering economic development, and enhancing energy security. While Armenia has made notable progress in rolling out electric vehicles and electrifying its rail network, it still struggles with a high dependence on imported fossil fuels, a lack of data transparency and weak co-ordination among government agencies. This roadmap is structured to…

Critical Mineral Traceability for Energy and Economic Security
Amid rising risks linked to the high concentration of critical mineral supply chains, the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for policymakers seeking to create diversified and responsible supply chains.This report provides insights from a first-of-its kind survey on traceability conducted by the IEA and OECD. More than 80 respondent companies active across supply chains of the six focus minerals (copper, lithium, nickel, cobalt, graphite and rare earth elements) provided results between October and December 2025. Drawing on…

Economic growth
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores economic growth. Why is energy efficiency important for economic growth? Energy efficiency allows countries to generate more economic activity using the same amount of energy. It is also linked to increased labour productivity and other economic benefits. Key facts Compared with 2000, today’s global economy produces 36% more GDP per unit of energy. Energy efficiency progress over the last 20 years means that close to an extra USD 50 trillion can today be produced using the same amount of energy. This energy efficiency bonus is equivalent to…

Energy security
…For instance, more efficient air conditioners in India could lower the impact of heatwaves on peak demand by 20% by 2030 and help reduce the risk of blackouts. Key analysis Energy efficiency policies in different sectors have been effective in reducing fossil fuel imports. In the European Union, the strongest reduction was in gas imports, driven by strong energy efficiency improvements in the industrial sector. Meanwhile, in Japan the strongest reductions were in oil imports, due to some of the most stringent fuel economy standards both for passenger and commercial vehicles. A closer look at electricity security Energy efficiency and…

Energy Efficiency Policy Toolkit
The Energy Efficiency Policy Toolkit is an interactive online tool that has been updated and expanded ahead of the 11th Annual Global Conference on Energy Efficiency in Montreal, Canada. It aims to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information and incentives. It also features a wide range of case studies, offering practical insights into the successful implementation of energy efficiency policies across diverse national and sectoral contexts.The Toolkit builds on earlier IEA work to advance energy efficiency policy. In 2022, the IEA introduced Policy Packages for Energy…

Powering Ireland’s Energy Future
Approaches for a secure, renewables-led electricity system to 2035 Ireland has emerged as a frontrunner in integrating wind power, which supplied around a third of its electricity in 2024. As this power system transformation continues, electricity is set to be the backbone for achieving Ireland’s climate, energy and socio-economic ambitions, making electricity security critical to realising progress in key areas including housing, digital infrastructure, transport and heat. Going forward, Ireland faces strategic choices on how to align its ambitions while ensuring secure electricity supply to 2035.This report assesses the outlook for Ireland’s energy security to…

Manufacturing and Trade Model
The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy…

Global Energy and Climate Model
Scenario analysis of future energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global…
