Affordability
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores affordability. Why is energy efficiency important for affordability? Energy efficiency measures can reduce energy bills for households, decrease energy poverty, and make access to energy services more affordable. Key facts Energy efficiency measures can reduce average household energy bills in advanced economies by up to one-third. In emerging economies, they can also improve access to energy services. For many products, such as refrigerators, highly efficient models use less than half of the energy of inefficient models. A best-in-class model can save up to…

Assessing emissions from LNG supply and abatement options
Drawing on the latest and best available data, this report provides a comprehensive estimate of greenhouse gas (GHG) emissions across the global liquefied natural gas (LNG) supply chain, including from upstream production, processing, and pipeline transmission to liquefaction, shipping, and regasification. It also discusses the significant emissions reductions that are technically feasible with today’s technologies including through methane abatement, electrification using low-emissions power, process efficiency improvements, and the elimination of routine flaring, as well as carbon capture, utilisation and storage (CCUS) for managing the naturally-occurring CO2 from LNG supply. Introduction Around 550 billion cubic metres (bcm) of natural…

Prospects for Natural Gas Certification
This report offers an overview of the role of certification in natural gas supply chains, provides a broad mapping of existing initiatives, highlights selected regulatory and market developments, identifies areas where improvements may be needed, and presents recommendations to support the development of credible certification frameworks.Certified natural gas refers to gas whose environmental and social attributes – such as greenhouse gas (GHG) emissions performance, water use, local community impacts and worker safety – have been independently verified against defined criteria or benchmarks. In 2024, around 7.5% of global natural gas production was certified, with volumes primarily originating from North America…

Key Questions on Energy and AI
Following the publication of the IEA’s landmark Energy and AI report in 2025, this report examines how the energy and AI nexus has evolved amid surging investment in data centres and rapid advances in model capabilities. Drawing on fresh datasets and analysis, it explores where electricity demand is rising, how quickly grids and supply chains can respond, and what these shifts mean for energy security, affordability and sustainability.

Energy security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

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…

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…

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…

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…

Vehicle software and software-defined vehicles
GEVO 2026 - Chapter 8 The transition from mechanical to software-based vehicle control has been underway for decades and has accelerated dramatically with the rise of EVs. Pure-play EV makers have pioneered the shift towards high-level, continuously updateable software-based vehicle control, speeding up the development and rollout of new features. Vehicles are evolving into software platforms for which users can access subscription‑based premium features, in the same way as for smartphones. A new design paradigm is emerging, with EVs at the forefront The digital transformation of the car industry is most evident in the emergence of software…
