Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Responding to Satellite Notifications from the Methane Alert and Response System
In 2023, the International Methane Emissions Observatory launched the Methane Alert and Response System, the first global system to provide free satellite-based alerts on major emission events to governments. Prompt reaction to MARS notifications has led to the successful mitigation of methane leaks in several countries. However, the global response rate to MARS notifications remains relatively low, suggesting that further measures may be required to transform satellite alerts into actionable responses for governments.The IEA, in collaboration with IMEO, has prepared this technical guidance document to assist governments seeking to improve action on MARS notifications and reduce methane emissions…

Portugal 2026
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Portugal and the IEA. It draws on the IEA’s extensive…

Ultra-fast charging batteries
GEVO 2026 - Chapter 8 New power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and therefore faster – charging systems. Advances in batteries and power electronics are improving EV performance Over the past decade, average EV battery pack energy density (Wh/kg) has increased by around 60%, while prices have fallen by roughly 75%. Moreover, in 2023, battery-related patents accounted for 40% of all energy-sector patents, suggesting that more developments are still to come. At the same time, new power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and…

Electricity 2026
Global power demand growth continues to rise rapidly as the Age of Electricity gathers pace, supported by the increasing electrification of industry, transportation, and the buildings sectors. Growing consumption is also coming from some of the most dynamic segments of global economies, such as artificial intelligence (AI), data centres, and evolving technological innovations.Against this backdrop, Electricity 2026 – the IEA’s annual report on global electricity systems and markets – provides in-depth analysis of the recent trends and policy developments underpinning this new era. It includes forecasts for electricity demand, supply and carbon dioxide (CO2) emissions for select countries, by…

Global Methane Tracker 2026
Around the world, many countries have made reductions in methane emissions a policy priority as part of their efforts to limit near-term global warming, enhance energy security, and improve air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for around 40% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker provides essential data on methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents the IEA’s latest sector-wide emissions estimates – based on the…

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…
