Grid investments
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores grid investments. Why is energy efficiency important for grid investments? As we enter the Age of Electricity, global electricity demand is rising rapidly – and so is the demand for the expansion of electricity grids. Energy efficiency can help close the gap between supply and demand, but often at a lower cost, and more quickly, than new generation and grid expansion. Key facts On average, energy efficiency costs less than half the amount it would cost to build new generation capacity and grid infrastructure, per unit of…

World Energy Outlook 2025
The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi…

The Implications of Oil and Gas Field Decline Rates Executive summary
Discussions on the future of oil and gas often overemphasise demand drivers and underappreciate supply drivers Debate over the future of oil and natural gas tends to focus on the outlook for demand, with much less consideration given to how the supply picture could develop. This asymmetry is misplaced and a thorough understanding of the rate at which production from existing oil and gas fields declines over time is more important than ever. The International Energy Agency (IEA) has long examined this issue. Decline rates – the annual rate at which production declines from an existing oil or gas field – underpin…

Why the growth of energy service companies is uneven globally
ESCO The global annual ESCO market growth rate has more than doubled over the past five years Energy efficiency is one of the most cost-effective tools for enhancing energy security, reducing household energy bills and supporting countries’ efforts to reduce emissions. Energy service companies (ESCOs) – firms that develop and implement energy efficiency projects typically financed through verified energy savings – are playing a growing role in delivering energy efficiency improvements across buildings, industry and transport infrastructure worldwide. By integrating project development, financing and performance guarantees, ESCOs can offer a proven way to reduce upfront investment barriers and shift technical and…

Global Hydrogen Review 2026 Policy
A total of USD 41 billion in public funding has been identified in policy updates made since the Global Hydrogen Review 2025 (GHR-25). Nearly two-thirds of this funding is linked to legislation in force and almost 25% has already been disbursed to projects, triggering final investment decisions (FID). As in GHR-25, most of the funding comes from advanced economies and for every dollar going to demand, about 1.5 dollars go to supply.The number of national hydrogen strategies has stabilised at 66 globally, and recent updates have focused either on implementing strategy actions (Brazil, Mauritania, Romania) or revising targets…

Gas Market Lessons from the 2022-2023 Energy Crisis
The 2022-2023 energy crisis tested the resilience of the global gas and LNG markets with the most severe gas supply shock in history. During the crisis, natural gas-importing markets around the world felt the pressures of record-high gas prices, including the scale-back in access to energy, the impediment to economic activity and the extra burden on government budgets. Market responses varied but governments were quick to react as the challenges of security of supply became apparent. Post-crisis, markets must continue to adapt as the effects of the crisis continue to influence security of gas supply…

Financing CCUS at Scale
How to Mobilise Private Capital Carbon capture, utilisation and storage (CCUS) is an important area of attention for governments and financiers as both look to balance policy and investment goals. Recent financial investment decisions of major projects show promise in a sector that is gaining momentum, but its future success depends on viable business models and effective risk allocation across the value chain.In this context, Financing CCUS at Scale is the IEA’s latest report on what it takes to move CCUS projects from the drawing board to operation. Building on expert interviews with leading financial institutions, the report…

Southeast Asia Energy Outlook 2026 Executive summary
Southeast Asia is a very dynamic region that is set to be a major driver of global energy demand growth, but the Middle East conflict has provided a stark wake-up call for the region’s energy system. Southeast Asia accounts for 9% of the world’s population and 4% of its GDP, but nearly 20% of global energy demand growth to 2035 under today’s policy settings. The disruption in global fuel markets has exposed deep structural vulnerabilities linked to import dependence, limited diversification and concentrated supply routes. Before the crisis, around 60% of Southeast Asia’s imports of…

Luxembourg 2026 Executive summary
Luxembourg has established ambitious climate and energy objectives, but more targeted policy measures are needed to meet them. Luxembourg’s climate and energy goals are aligned with the European Union (EU) targets for a 55% reduction in greenhouse gas (GHG) emissions by 2030 and a 90% reduction by 2040, and it has legally enshrined net zero emissions by 2050. Despite rapid population and economic growth, energy-related emissions have already fallen by 40% since 2005, reflecting the success of early measures. Public support for climate action is also robust, providing a strong foundation for the next phase of the transition…

Electricity 2026 Flexibility
Evolving generation and demand patterns reshape power system needs The Age of Electricity is underpinned by rising investments in new resources. These include growing converter-based variable solar PV and wind, battery storage systems, as well as spatially and temporally concentrated demand from EVs, heat pumps and large loads like data centres. Combined with the expansion and upgrade of transmission and distribution grids, substantial increases in the flexibility of power systems are required for secure and cost-effective integration of generation, load and storage technologies that characterise this new era.Last year’s report, Electricity 2025, focused on measures to…
