Global Energy Review 2026
Global Energy Review 2026 This edition of the Global Energy Review provides the first full assessment of trends across the entire energy sector in 2025, with data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions.The report covers estimates of energy demand by region and by source and fuel in 2025; developments in electricity demand and supply; deployment of selected energy technologies; and estimates of energy-related CO2 emissions. The report also assesses trends in energy intensity and analyses the impact of factors, such as weather effects, on energy demand and…

Country
United Kingdom
The United Kingdom has been an early player in the energy transition, being among the first countries to set a net zero target by 2050 and to put in place carbon budgets. UK emissions have already fallen by around 50% since 1990, indicating a strong start. Looking ahead, an important pillar of the energy transition will be decarbonising the power sector through sizeable new investments in renewables and nuclear while also focusing on new technologies such as CCUS, hydrogen and small modular reactors. As a historic oil and gas producer, the UK is looking to address declining North Sea production…

Mozambique 2024
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Mozambique and the IEA. It draws on the IEA’s extensive…

Economic growth
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores economic growth. Why is energy efficiency important for economic growth? Energy efficiency allows countries to generate more economic activity using the same amount of energy. It is also linked to increased labour productivity and other economic benefits. Key facts Compared with 2000, today’s global economy produces 36% more GDP per unit of energy. Energy efficiency progress over the last 20 years means that close to an extra USD 50 trillion can today be produced using the same amount of energy. This energy efficiency bonus is equivalent to…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap The hydrogen opportunity
Highlights Ukraine has 18-38 Mtpa of technical renewable hydrogen potential, though economic constraints would result in lower potential. Most potential is in regions with scarce water resources and competition from other industrial activities. Domestic demand for use for steel and fertilisers could reach 2.2 Mtpa, if pre-invasion capacity is restored, and the government target has set a target of 7.2 Mtpa of production by 2050. Most hydrogen production projects proposed prior to the invasion are close to the border with the European Union.Ukraine has a technical potential for solar PV and onshore wind equivalent to 9‑14 times its pre…

Ramping up Heat Pumps in Moldova: A Roadmap Executive summary
Moldova’s new National Energy and Climate Plan (NECP) lays out the country’s ambition to improve energy efficiency, reduce fossil fuel demand and decarbonise its economy. Buildings account for more than half of Moldova’s final energy consumption, with three-quarters of that used for space and water heating. Currently, these needs are met chiefly by imported natural gas and domestic biomass – two fuel sources that suffer from availability and sustainability issues. Heat pump technology offers Moldova an effective means of accelerating the transition in building heating. This roadmap discusses the status of Moldova’s heating sector, the potential…

United States
The United States introduced major energy and climate policy reforms which put the country on a path towards a clean, secure and affordable energy system for a net zero economy. The reforms aim to strengthen infrastructure deployment and resilience, include a major focus on clean energy manufacturing, improving diverse supply chains and affordability, enhancing equity and the creation of high-quality clean energy jobs.
The US plays a significant role in supporting international energy security as the world’s largest producer of oil and exporter of liquified natural gas. A wave of clean energy investment means the US is today…- Overview

Energy Efficiency Policy Toolkit
To accelerate action on energy efficiency, the IEA created the Policy Packages for Energy Efficiency in 2022 to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information, and incentives.The IEA then developed an Energy Efficiency Policy Toolkit that integrates the Policy Package for Energy Efficiency, with concrete examples for each end-use sector. The Toolkit shares strategic principles to guide policy makers to enhance and expand their energy efficiency policies and programmes.Building on this foundation, the Energy Efficiency Policy Toolkit, updated on the occasion of the 10th Annual Global Conference on Energy Efficiency in…

Turkmenistan
Turkmenistan’s government is continuously investing in oil and gas, to modernise and expand the electricity and heat sector by 2020. Moreover, the energy sector is almost fully subsidised, with citizens receiving free electricity, heat and gas up to a certain level of consumption, until 2030, but the government is taking steps to reduce subsidies to curb domestic demand and increase exports. Turkmenistan is part of the EU4Energy Programme, an initiative focused on evidence-based policymaking for the energy sector.
