World Energy Investment 2026 Regional dashboards
Despite the destabilising effect of the Middle East conflict, capital flows to the energy sector are expected to grow to USD 3.4 trillion in 2026, a 5% rise from 2025, mainly from China, the US, and the EU. Clean energy investment grows to USD 2.2 trillion, almost double that of fossil fuels. Investment in clean energy increases year-on-year by 7% in advanced economies and in China, while 4% in other emerging markets, reflecting regional differences with a shared focus on energy security.

World Energy Investment 2025 How we track investment in energy
Tracking energy investment The way investment is measured across the energy spectrum varies, largely because of differences in the availability of data and the nature of expenditures. This document highlights the methodology used to ensure that the estimates are consistent and comparable across sectors in the World Energy Investment 2025 (WEI 2025) report and other publications from the International Energy Agency.The IEA measures investment as the ongoing capital spending on assets. For some sectors, such as power generation, this investment is spread out evenly from the year in which a new plant or upgrade of an existing one takes…

Gaining an Edge Energy demand and competitiveness
Energy is at the centre of competitiveness amid high costs, growing demand, and rising trade pressures Energy is a vital input into all productive sectors of the economy. In an environment of fierce global competition and shifting trade patterns, energy costs are a major determinant of long-term investment, jobs and business competitiveness. Finding ways to reduce energy costs while producing more or better products is good for both profitability and overall economic growth. While energy prices are volatile in many countries, recent high prices combined with instability and fragmentation in energy markets have widened energy price gaps between regions…

World Energy Investment 2025 Executive summary
Despite elevated geopolitical tensions and economic uncertainty, this tenth edition of the IEA’s World Energy Investment shows that capital flows to the energy sector are set to rise in 2025 to USD 3.3 trillion, a 2% rise in real terms on 2024. Around USD 2.2 trillion is going collectively to renewables, nuclear, grids, storage, low-emissions fuels, efficiency and electrification, twice as much as the USD 1.1 trillion going to oil, natural gas and coal. Open questions about the economic and trade outlook means that some investors are adopting a wait-and-see approach to new project approvals, but we have yet…

Global Energy Review 2025 CO2 Emissions
Energy sector carbon emissions reached a new record in 2024 Total energy-related CO2 emissions increased by 0.8% in 2024, hitting an all-time high of 37.8 Gt CO2. This rise contributed to record atmospheric CO2 concentrations of 422.5 ppm in 2024, around 3 ppm higher than 2023 and 50% higher than pre-industrial levels. In 2024, CO2 emissions from fuel combustion grew by around 1% or 357 Mt CO2, while emissions from industrial processes declined by 2.3% or 62 Mt CO2. Emissions growth was lower than global GDP growth (+3.2%), restoring the decades-long trend of decoupling emissions…

Energy Efficiency Policy Toolkit Appliances
Introduction Appliances represent 45% of electricity demand in buildings and are responsible for almost 3 gigatons (Gt) of CO₂ emissions. Doubling the global annual energy intensity improvement by 2030 would require appliances to become 30% to 40% more efficient. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulations such as minimum energy performance standards (MEPS) can ensure that the least efficient equipment is not sold on the market. MEPS also encourage suppliers to increase the efficiency of the appliances they produce, accelerating the improvement of efficiency on the market. In…

Global Energy and Climate Model Stated Policies Scenario (STEPS)
The Stated Policies Scenario (STEPS) has a long pedigree in the International Energy Agency (IEA) family of scenarios. It was introduced in 2019 with this name, but it has much in common with the previous New Policies Scenario that dates back to the 2010 edition of the World Energy Outlook (WEO). The intention of this scenario is to reflect the prevailing direction of travel for the energy system based on a detailed reading of the latest policy settings in countries around the world. It takes into account specific energy, climate and related industrial policies that have been adopted or put…

Global Hydrogen Review 2026 Executive summary
The conflict in the Middle East has disrupted global production and trade of hydrogen-based products The Middle East is a major producer of hydrogen-based products, and the conflict has strongly impacted their production. The Middle East is home to around one-sixth of global hydrogen production, the majority dedicated to the production of chemicals, fertilisers and refined oil products. The region accounts for more than 10% of global refining capacity, ammonia and urea production, and close to 17% of methanol production. Several refineries and petrochemical plants have halted operations due to supply disruptions and the impossibility of exporting…
