Global Energy and Climate Model Understanding GEC Model scenarios
Overview The IEA’s medium- to long-term outlook publications – including the World Energy Outlook (WEO) and Energy Technology Perspectives (ETP) – use a scenario approach relying on the Global Energy and Climate (GEC) Model to examine future energy trends.Each scenario has the same starting point and is based on the latest data for energy supply and demand, markets, technology costs and policies, as well as the same pathways for future population and economic growth.The energy system described and explored in each scenario evolves in a distinctive pathway that delivers energy services with a different mix of technologies and…

Scaling Up Transition Finance What is transition finance?
Developments and current status Many energy investments defy a simple binary classification between “clean” and “dirty”: there are also the “in-between” investments that can deliver material emissions reductions but that do not bring emissions to zero. These investments have historically been difficult to categorise due to differences in energy pathways and timeframes across regions and have been the subject of debate, including over whether and how they should be supported.Transition finance refers to financial activities that can contribute to emissions reductions, particularly in hard-to-abate sectors as well as in emerging market and developing economies (EMDE) where…

Energy Technology Perspectives 2026 Executive summary
Despite headwinds, the markets for clean energy technologies and fuels are expanding rapidly Deployment of many clean energy technologies, fuels and materials has been growing fast, but shifting policies, economic conditions and technological progress are creating uncertainty about their prospects and economic potential. Against this backdrop, the IEA’s flagship technology publication Energy Technology Perspectives (ETP) aims to separate the signal from the noise, by providing timely data, scenarios and analysis across deployment, manufacturing, trade, competitiveness and security. At a time when misjudging the moment risks wasting capital or stalling momentum, this report has been designed to help decision makers…

Global Energy Review 2026 Oil
Oil demand growth remained subdued in 2025 Oil demand increased in 2025 by 0.65 mb/d (million barrels per day) or 1.2 EJ, but this 0.7% rise marked a further slowdown from 2024’s already-muted 0.75 mb/d of growth. The increase in both years was in line with IEA projections. The 2025 increase fell well short of the 2010-19 average annual rise of 1.4 mb/d, offering further evidence of a structural deceleration in oil markets.This slowdown mainly reflected weaker growth in petrochemical feedstock use. Demand for naphtha, liquefied petroleum gas…

Ensuring a Strong Labour Dimension for Just and Inclusive Energy Transitions Just and Inclusive Energy Transitions
Workers play a critical role in the global energy system, providing key services across many areas of the energy sector. To give a greater voice to the labour perspective in energy and climate policy discussions, the IEA Executive Director convened the Clean Energy Labour Council in 2022. The Labour Council is made up of representatives of the world’s most important national trade unions and trade union confederations, as well as prominent thinkers on the topic, to foster engagement between the IEA, energy policy makers, and the labour movement.One of the main topics for the IEA Clean Energy Labour…

Gas Market Lessons from the 2022-2023 Energy Crisis Conclusion and lessons learned
Market environment is structurally and geopolitically more fragile One of the primary and most fundamental consequences of the energy crisis is the shift into a structurally more fragile natural gas market environment, compounded by geopolitical uncertainty. The drastic reduction in Russian pipeline flows to Europe also represented a loss of traded gas volumes in the global market. Concurrently, this drove an equally significant reduction in the availability of swing production capacity that had previously provided a degree of price-responsive supply modulation to both the European and global markets. In turn, this led to an increased reliance on LNG trade…
