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.

Energy Efficiency 2025
Market Report Energy Efficiency 2025 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, investment, employment and policy. The report provides sector-specific analysis on industry, buildings, appliances and transport and explores system-wide themes such as emissions reductions, energy security, affordability and competitiveness. This report is launched in parallel with an update to the IEA Energy Efficiency Progress Tracker, which can be accessed through the IEA website.

China’s Official Energy Finance in Emerging and Developing Economies
Evolving institutions, instruments and implications for clean energy transitions Global energy investment exceeded USD 3.3 trillion in 2025, but capital flows remain uneven. Emerging market and developing economies (EMDE) outside China attracted just 27% of total energy investment and 18% of clean energy spending, despite accounting for nearly two-thirds of the global population and the bulk of future demand. Addressing this imbalance requires mobilising more capital from diverse sources into EMDE energy systems.China continues to play a central role in global energy investment flows because of its large domestic investments and its large external capital spending on energy. Since…

Global Hydrogen Review 2025
…future prospects of hydrogen, and to inform discussions at the Hydrogen Energy Ministerial Meeting organised by Japan.The sector has progressed significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen production projects have gone from just a handful of demonstrations to more than 200 committed investments for projects that are increasing in number and in scale, reflecting the importance of hydrogen for climate goals, energy security and industrial competitiveness. Nevertheless, growth has not met all of the expectations raised at the start of the decade and remains uneven. Uncertainties about costs, infrastructure readiness and…

Global Energy Review 2025
…including oil, natural gas, coal, renewables and nuclear power. This growth was led by the power sector, with demand for electricity rising almost twice as fast as wider energy demand due to higher demand for cooling, rising consumption by industry, the electrification of transport and the growth of data centres and artificial intelligence. Nearly all of the rise in electricity demand was met by low-emissions sources, led by the record-breaking expansion of solar PV capacity, with further growth in other renewables and nuclear power. Gas demand also picked up substantially, while oil and coal consumption increased more slowly…

Global Methane Tracker 2025
Methane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, and rapid and sustained reductions in methane emissions are key to limiting near-term global warming and improving air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for more than 35% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker is an essential tool for raising awareness about methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents our latest…

National Climate Resilience Assessment for Algeria
…per decade, significantly driving up cooling needs. Between 2022 and 2024, residential electricity demand increased by 15%, much of which was due to higher usage and uptake of air conditioning. Future heatwaves and extreme temperatures could pose a risk to Algeria’s electricity security. By mid-century, more than 70% of Algeria’s gas-fired power plants are projected to face at least 40 days with a maximum temperature above 35 °C or more, in all global warming scenarios assessed. High temperatures decrease the nameplate capacity of gas-fired power plants and reduce the carrying capacity of the electrical grid. These…

Outlook for Biogas and Biomethane
A global geospatial assessment Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential…

Policy options to accelerate distributed solar PV in Ukraine
…storage deployment will support Ukraine in establishing energy security.In the year following the Russian Federation’s full-scale invasion of Ukraine in 2022, available dispatchable power generation capacity halved from roughly 38 GW to 19 GW. After severe attacks in spring 2024, capacity declined further, down to 12 GW. Towards the end of 2024 Ukraine was able to restore 3 GW and has worked to restore and add additional capacity throughout 2025, despite ongoing attacks.Distributed solar PV has played a key role, providing cost effective and rapid increases in electricity generation capacity, contributing to system resilience and overall energy security…

Blueprint for Action on Just and Inclusive Energy Transitions
Global Commission on People-Centred Clean Energy Transitions: Designing for Fairness June 2025 This year’s G20 President, South Africa, is placing a major focus on just and inclusive energy transitions. This builds on Brazil’s 2024 G20 Presidency which elevated just and inclusive energy transitions as a priority on the global agenda. Under Brazil’s Presidency, the G20 leaders endorsed ten voluntary Principles for Just and Inclusive Energy Transitions. The Global Commission believes these principles form a powerful framework for how governments, each navigating their own set of circumstances, can proceed with clean energy transitions that provide benefits and…
