World Energy Investment 2025 United States
Energy investment policies in the United States reflect its prioritisation of energy security Energy investment in the United States reflects its prioritisation of energy security, with a subsequent strategic push to establish a presence in emerging value chains and to supply international markets. Since becoming a net energy exporter in 2019, a remarkable turnaround from its high previous reliance on imports, the country has continued to expand its global energy role. In 2024 it was the world’s largest producer of oil and gas (20% of global output), as well as a major investor (25% of total investment). This growth…

Global Energy and Climate Model Policies
Policies database Underpinning the scenario analysis of the GEC Model, an extensive effort is made to update and expand the list of energy and climate-related policies and measures that feed into our modelling. Assumptions about government policies are critical to this analysis and are the main reason for the differences in outcomes across the scenarios. A summary of some of the key policy targets and measures for different sectors by selected countries and regions can be found in the Annex B of WEO-2025.Although all care has been taken to ensure accuracy, completeness and clarity of content in…

The Implications of Oil and Gas Field Decline Rates Executive summary
Discussions on the future of oil and gas often overemphasise demand drivers and underappreciate supply drivers Debate over the future of oil and natural gas tends to focus on the outlook for demand, with much less consideration given to how the supply picture could develop. This asymmetry is misplaced and a thorough understanding of the rate at which production from existing oil and gas fields declines over time is more important than ever. The International Energy Agency (IEA) has long examined this issue. Decline rates – the annual rate at which production declines from an existing oil or gas field – underpin…

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…

Fatih Birol
Executive Director. As Executive Director of the International Energy Agency, Dr Fatih Birol (@fbirol) has positioned the IEA at the forefront of global efforts to advance a secure, affordable and sustainable energy system. Since taking office in 2015, he has modernised the Agency by broadening its energy security mandate beyond oil to include electricity, natural gas, renewables and critical minerals, strengthened the Agency's global leadership in clean energy transitions and expanded IEA membership to include major emerging countries. As a result, the IEA’s share of global energy demand coverage has increased from 40% to over 80%. He has also played a central role in the global response to major energy security emergencies, including those triggered by the invasion of Ukraine in 2022 and the 2026 Strait of Hormuz crisis.Dr Birol joined the IEA in 1995 and steadily rose through the ranks from junior analyst to Chief Economist, where he oversaw the flagship World Energy Outlook. Throug...

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…

Fossil Fuel Subsidies
This approach compares average end-user prices paid by consumers with reference prices that correspond to the full cost of supply. The price gap is the amount by which an end-use price is short of the reference price. Its existence indicates the presence of a subsidy. In a given economy, the basic calculation of subsidies for a product is:Subsidy = (Reference price - End-user price) × Units consumedThese calculations require substantial data. End-user price and consumption data are drawn from IEA data and, where necessary, from government sources and other reports. The estimates are also sensitive to reference…
