Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…

State of Energy Policy 2026
…with a special focus on government spending, energy efficiency regulations, and the contribution of the energy sector to nationally determined contributions and long-term net zero pledges.This year’s report brings an extensive examination of energy security policies to the period 1973-2025, from oil and natural gas to clean energy technology supply chains and critical minerals. It also spotlights the policy momentum around energy access, most particularly in sub-Saharan Africa, taking stock of the policy progress since the IEA Summit on Clean Cooking in Africa in 2024.The State of Energy Policy series draw on the Global…

Delivering Sustainable Fuels
Pathways to 2035 Sustainable fuels – including liquid biofuels, biogases, low-emissions hydrogen and hydrogen-based fuels – offer multiple benefits for the energy sector. They complement electrification and energy efficiency in energy transitions, and are particularly important for sectors that continue to be reliant on fuel-based solutions such as aviation, shipping, and parts of road transport and industry. Sustainable fuels can also enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a…

Clean Energy Technology Supply Chain Data
Challenges and potential solutions Energy security in the Age of Electricity is inextricably linked to securing the supply chains for clean energy technologies and the equipment and materials used to manufacture them. As countries continue to pursue energy transitions and to direct investments to these technologies, guided by industrial strategies, a detailed understanding of their supply chains has an essential role to play. The availability of good-quality, timely data is crucial to gaining this understanding and to identifying and addressing supply chain vulnerabilities.This report is provided as an input to the discussions taking place as part of the…

Rare Earth Elements
Pathways to secure and diversified supply chains The critical role of rare earth elements in strategic applications, ranging from energy technologies and advanced electronics to aerospace and defence systems, combined with their highly concentrated supply chains, has elevated their importance in both energy and broader economic security discussions in recent years. This report assesses the current state of the rare earth elements market, examining demand and supply dynamics and key technological developments. It analyses the full value chain from mining to permanent magnet production, evaluates vulnerabilities across supply chains, and highlights the implications of potential supply disruptions. Based on these…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

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…

Coal 2025
Analysis and forecast to 2030 Coal is a cornerstone of electricity generation in many countries as well as the single largest source of carbon dioxide emissions globally, placing it at the centre of international dialogues on energy. At a time of uncertainty and change for energy systems around the world, a range of different trends could shape coal markets in the years ahead.On the one hand, recent policy changes supporting coal could drive consumption higher, as could surging electricity demand in economies across the world, since two-thirds of global coal use today is for power generation. On the…

Policy Toolbox for Industrial Decarbonisation
The Policy Toolbox for Industrial Decarbonisation is a repository of policy instruments available to assist governments as they design, develop and implement their strategies for industrial decarbonisation. This work, undertaken as part of the Climate Club's Work Programme, builds on the policy toolbox outlined in IEA’s 2022 Achieving Net Zero Heavy Industry Sectors in G7 Members report, with the addition of further details on the instruments and considerations for implementation.A robust industrial decarbonisation policy strategy is likely to include multiple different instruments, as governments choose the instruments that are most suited to their individual circumstances and objectives…
