Global Energy Review 2026 Global trends
Demand for all fuels and technologies grew in 2025 Global energy demand grew by 1.3%, or 8 exajoules (EJ), in 2025. This represents a notable slowdown in energy demand growth from 2024, when it increased by 2%. A range of factors explain this. Firstly, although the global economic expansion remained robust, the rate of growth was slightly slower than in 2024, with slower growth in energy-intensive industries in some regions. Secondly, lower temperatures relative to 2024 led to lower cooling demand. Thirdly, energy intensity improvements accelerated.All energy sources contributed to meeting global energy demand growth in 2025…

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…

Policy options to accelerate distributed solar PV in Ukraine Policy options and implications
Overview of policy instruments for distributed solar PV deployment Globally, government policies and incentives have been the main driver for distributed PV deployment. These instruments can be differentiated between 1) policies targeting investment costs and 2) policies focusing on consumption and the sale of electricity.Policies targeting investment costs usually take the form of direct financial incentives that aim to reduce initial investment costs and make distributed PV systems more affordable for consumers. They include:Grants and rebates: a fixed subsidy, usually with a one-time payment.Tax credits: amounts taxpayers can subtract from taxes, usually based on a percentage…

World Energy Investment 2025 Source, flows and destination of global energy-related investment spending
Most energy investment is supported by commercial finance and made by private sponsors, but the sources of finance vary widely by technology and region. Today, 75% of the available finance for investment in the energy sector is commercial finance, but domestic and international public finance play important roles that vary widely across regions and sectors.

Global Energy Review 2026 Natural gas
Natural gas demand growth slowed in 2025 Following a strong increase of 2.8% in 2024, global gas demand growth slowed significantly in 2025 amid weaker industrial activity and relatively high spot liquefied natural gas (LNG) prices in the first half of the year. Demand increased by 1% in 2025, translating to an increase of around 40 bcm (or 1.4 EJ) in absolute terms. Incremental demand was largely concentrated in the United States and the European Union – where it was supported by colder winter weather – and in the Middle East, where gas use in the power sector grew rapidly…

Gaining an Edge Unlocking the potential of energy efficiency
Efficiency opportunities at the firm level At the firm level, energy efficiency offers untapped opportunities to reduce costs in both light and heavy industries In a competitive environment, firms are seeking to reduce costs, support sustainable growth and meet dynamic market demands. Energy is an important component of production costs in many industrial sectors, although its share varies by industry. These differences are influenced by the type and complexity of production. Heavy industries, such as steel, cement and chemicals, tend to be more energy intensive due to the large-scale processes and high thermal demands. Light industries, such as electronics…
