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…

COP28 Tripling Renewable Capacity Pledge 2025: Update Key Findings
New Nationally Determined Contributions (NDCs) show limited reflection of the pledge to triple global renewable capacity by 2030 agreed at COP28 Between COP28 and the end of COP30, only about two-thirds of NDCs have been updated (128) and fewer than half of these (53) explicitly reference the global tripling goal. Even fewer (32) contain quantifiable renewable capacity ambitions for 2030. NDCs continue to under-represent current government ambitions for installed renewable capacity by 2030 The NDC 3.0 round does not fully capture countries’ 2030 renewable capacity ambitions in all submitted NDCs. Including 2030 ambitions from previous NDC cycles, total…

Electricity 2026
Global power demand growth continues to rise rapidly as the Age of Electricity gathers pace, supported by the increasing electrification of industry, transportation, and the buildings sectors. Growing consumption is also coming from some of the most dynamic segments of global economies, such as artificial intelligence (AI), data centres, and evolving technological innovations.Against this backdrop, Electricity 2026 – the IEA’s annual report on global electricity systems and markets – provides in-depth analysis of the recent trends and policy developments underpinning this new era. It includes forecasts for electricity demand, supply and carbon dioxide (CO2) emissions for select countries, by…

Responding to Satellite Notifications from the Methane Alert and Response System
In 2023, the International Methane Emissions Observatory launched the Methane Alert and Response System, the first global system to provide free satellite-based alerts on major emission events to governments. Prompt reaction to MARS notifications has led to the successful mitigation of methane leaks in several countries. However, the global response rate to MARS notifications remains relatively low, suggesting that further measures may be required to transform satellite alerts into actionable responses for governments.The IEA, in collaboration with IMEO, has prepared this technical guidance document to assist governments seeking to improve action on MARS notifications and reduce methane emissions…

World Energy Investment 2025 Eurasia
Eurasia has seen a significant decline in oil investment since 2015, although fossil fuels maintain their dominance in the region's energy mix Fossil fuels dominate the overall energy production and investment mix in Eurasia. Countries in the region face common challenges, including significant temperature swings from harsh winter conditions to warm summers, ageing infrastructure and often inefficient patterns of energy use: the energy intensity of Eurasia’s GDP is around 70% higher than the global average. Annual energy investment in Eurasia was almost USD 190 billion in 2015, but has since followed a downward trend, reaching its lowest point in the…

Ensuring a Strong Labour Dimension for Just and Inclusive Energy Transitions
IEA Clean Energy Labour Council Workers play a critical role in the global energy system, providing key services across many areas of the energy sector. To give a greater voice to the labour perspective in energy and climate policy discussions, the IEA Executive Director, Dr. Fatih Birol, convened the Clean Energy Labour Council in 2022. The Labour Council brings together representatives of the world’s most important national trade unions and trade union confederations, as well as prominent thinkers on the topic, to foster engagement between the IEA, energy policy makers, and the labour movement.The IEA Clean Energy Labour…

Portugal 2026 Executive summary
Thanks to steady expansion of hydropower, wind power generation and solar photovoltaics (PV) in recent years, Portugal has one of the lowest carbon intensities of electricity generation among IEA Member countries. Portugal is entering a mid‑transition that requires managing two interconnected energy systems that are moving in opposite directions: one is based on renewables and electrification and must scale up rapidly; the other is a legacy fossil fuel system that must decline in an orderly way to avoid stranded assets and price shocks. Electricity is becoming the central pillar of energy security and the main driver of emissions reductions.Portugal…

Critical Mineral Traceability for Energy and Economic Security
Amid rising risks linked to the high concentration of critical mineral supply chains, the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for policymakers seeking to create diversified and responsible supply chains.This report provides insights from a first-of-its kind survey on traceability conducted by the IEA and OECD. More than 80 respondent companies active across supply chains of the six focus minerals (copper, lithium, nickel, cobalt, graphite and rare earth elements) provided results between October and December 2025. Drawing on…

Global Energy Review 2026 Technology: Nuclear
In 2025, 3 GW of new nuclear capacity came online, with China, India and Russia each completing work on a new reactor. However, these additions were offset by the retirement of 3 GW of nuclear capacity, two-thirds of which was in Belgium. In total, global nuclear capacity remained at 420 GW at the end of 2025, with reactors in operation in over 30 countries. There were ten construction starts in 2025 – nine in China and one in Russia – with a total capacity of 12.2 GW. Over the past decade, 94% of nuclear reactors that started construction were of…
