Global Energy and Climate Model About the Global Energy and Climate Model
Overview Since 1993, the IEA has provided medium- to long-term energy projections using a continually evolving set of detailed, world-leading modelling tools. First, the World Energy Model (WEM) – a large-scale simulation model designed to replicate how energy markets function – was developed. A decade later, the Energy Technology Perspectives (ETP) model – a technology-rich bottom-up model – was developed for use in parallel to the WEM.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…

Global Hydrogen Review 2025 Five key questions about hydrogen
Is the slow progress of projects derailing the hydrogen sector? Recent headlines reporting project delays, cancellations and downward revisions of ambitions for the adoption of low-emissions hydrogen, have led many to question whether the industry has hit another “hype cycle” like those in the 1970s, 1990s, and early 2000s. However, a deeper analysis reveals a different story. Despite falling short of the ambitious targets from the early 2020s, the sector is achieving remarkable milestones that demonstrate clear progress.The scale of electrolyser projects is growing fast. In 2021, the world's largest reached 30 MW. In 2025, a 500 MW project…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap Unlocking the opportunity - A roadmap for action
Highlights Hydrogen represents a long-term opportunity for Ukraine, but action is required in the near term to unlock the full benefits. Work over the first 2-3 years after the war ends can lay the foundations for future market growth without large commitments, such as through studies, planning for regulation and de-risking. In a second stage (5 years) pilot projects would be built to develop experience in the private sector and inform policy. A final stage (10-20 years) would incorporate lessons learnt, with a focus on standardisation, replication and simplification to support large-scale deployment. Each stage…

Uzbekistan
Despite being energy self-sufficient thanks to its gas sector, Uzbekistan's ageing infrastructure struggles to meet growing domestic demand. Losses, overuse and financing remain problematic. Wide-ranging reforms focused on improving and diversification the energy sector are being introduced and the government has adopted the Strategy of Actions 2017-2021, which prioritizes improving energy efficiency and increasing generating capacity and use of renewables. Uzbekistan is part of the EU4Energy Programme, an initiative focused on evidence-based policymaking for the energy sector.

Oil Market Report - June 2026
The IEA Oil Market Report (OMR) is one of the world's most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights Global oil demand is forecast to decline by 1.1 mb/d y-o-y in 2026. This represents a downgrade of 700 kb/d compared with our May Report, as 2Q26 deliveries plunged by 5 mb/d y-o-y in the face of higher…

Financing the ASEAN Power Grid
The Association of Southeast Asian Nations (ASEAN) has a long history of electricity system connectivity, and the development of the ASEAN Power Grid (APG) is central to achieving a sustainable, secure and affordable energy transition across the region. Delivering the APG will require a significant step‑change in investment over the coming 15 years, and unlocking financing from a diverse range of sources will be essential for this to happen. Yet financing approaches and business models have not evolved at the pace required to support an increasingly ambitious and complex pipeline of interconnector projects.This report examines how interconnectors are approached…

Renewables 2025 Renewable electricity
Renewable electricity additions for 2025-2030 total 4 600 GW – equal to the combined installed power capacity of China, the European Union and Japan Globally, renewable power capacity is projected to increase almost 4 600 GW between 2025 and 2030 – double the deployment of the previous five years (2019-2024). Growth in utility-scale and distributed solar PV more than doubles, representing nearly 80% of worldwide renewable electricity capacity expansion. Low module costs, relatively efficient permitting processes and broad social acceptance drive the acceleration in solar PV adoption.Distributed solar PV applications (residential, commercial, industrial and off-grid projects) account for 42…

Israel
Israel endorsed a target of generating 10% of the country’s electricity from renewable sources in 2020. Solar thermal and photovoltaic power plants are expected to account for over 70% of total generation, with the remainder deriving from household PV units, wind energy and biomass.
The statistical data for Israel are supplied by and under the responsibility of the relevant Israeli authorities. The use of such data by the OECD is without prejudice to the status of the Golan Heights, East Jerusalem and Israeli settlements in the West Bank under the terms of international law.- Overview
