Grid investments
…or over a decade for nuclear. Key analysis IEA analysis of nine major regions shows that increasing electricity generation and grid capacity by one terawatt-hour (TWh), will require investments of USD 30 to 110 million in emerging economies and USD 75 to 150 million in advanced economies. In order to save the same amount of electricity, energy efficiency measures would cost only between USD 10 million and 50 million. A closer look at grid management The deployment of energy efficiency measures typically requires less time than the implementation of most new generation and grid infrastructure. On average, new generation and grid infrastructure can take years…

Economic growth
…1 spent on energy efficiency programmes would generate between USD 4 and USD 7 in GDP between 2017 and 2030. In the United States, a study funded by the Department of Energy estimated that doubling energy productivity could result in a net GDP increase of USD 922 billion between 2015 and 2030. Increase in labour productivityAn analysis of over 15 000 European firms found that those investing in energy efficiency can see increases in labour productivity – the amount of economic activity per unit of labour – between 1.4% and 3.6% compared with firms with no investment in energy efficiency.Improvement…

Scaling Up Transition Finance
Scaling Up
Transition
Finance Actions by emissions-intensive sectors, companies and countries are crucial to placing the world on a sustainable pathway. Yet investments that could deliver meaningful reductions in their environmental footprint often do not receive sufficient financial support. Currently, finance is drawn heavily to certain “green” assets and activities. While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost-competitive. This is where transition finance comes in: it can help emissions-intensive countries, companies and sectors shift over time towards…

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…

Clean Energy Transitions Programme 2024
…the Conference of the Parties (COP) and the Group of 20 (G20), ensuring that clean energy goals are integrated into international dialogues. The impact of the CETP extends to critical areas like energy efficiency, critical minerals, climate resilience, mobilising investment and reducing methane emissions, which are central to the global energy transition.Through innovation and multilateral collaboration, the CETP exemplifies the IEA's strategy of promoting clean energy transitions that are not only secure and sustainable but also inclusive and affordable. It remains a cornerstone of global efforts to accelerate the clean energy transition, driving tangible, transformative change across the world.

Tracking SDG7: The Energy Progress Report, 2025
…These goals will demand a fundamental shift in energy production, distribution, and consumption, supported by greater investment, enabling policies, continued innovation, enhanced ambition and long-term planning. Addressing uneven progress and regional disparities requires collaboration among governments, the private sector, international organizations, and civil society, including on ensuring access to adequate financing and technical assistance. To foster inclusive transitions, particular attention is required to help women and marginalized communities benefit from the energy transition. Empowering people—especially young people—with the skills and knowledge to engage in the energy sector fosters a forward-looking mindset that is crucial for long…

The Implications of Oil and Gas Field Decline Rates
…and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new report – based on analysis of the production records of around 15 000 oil and gas fields around the world – explores the implications of accelerating decline rates, growing reliance on unconventional resources, and evolving project development patterns for the global oil and gas supply landscape, for energy security and for investment. It also provides regional insights…

Delivering Sustainable Fuels
…and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a path to nearly double from 2024 levels by 2030 and quadruple by 2035. Progress must occur on multiple fronts to increase uptake and foster a large and diverse set of sustainable fuel pathways. This calls for a shared global vision for sustainable fuels, along with targeted policies to bridge costs gaps with conventional fuels, innovation to expand production potential, robust and mutually agreed carbon accounting methodologies to ensure that sustainability criteria are met, long-term investment in infrastructure, and…

State of Energy Policy 2026
The IEA State of Energy Policy 2026 report provides with a unique review of policy progress made in 2025 across all energy sectors and instruments, 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…
