Multiple Benefits of Energy Efficiency
As energy efficiency continues to gain attention as a key resource for economic and social development across all economies, understanding its real value is increasingly important. The multiple benefits approach seeks to expand the perspective of energy efficiency beyond the traditional measure of energy savings by identifying and measuring its impacts in full bloom.

Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

World Energy Investment 2025 Southeast Asia
In the past, Southeast Asia’s rapid economic growth was mostly driven by fossil fuels but clean energy now accounts for almost half of energy investment Southeast Asia is a rapidly developing region, with GDP per capita increasing by more than 30% since 2015. During the last ten years, energy demand has increased by over 35%, with electricity demand rising by more than 60%. Driving this is a 12% increase in electricity access rates, growing consumption in industry, urbanisation and rising incomes creating demand for cooling and other appliances. Historically, this rising energy demand has been met by fossil fuels…

Global Methane Tracker 2026 Policy trends
Existing policies and regulations would cut energy sector emissions by 25% by 2035 – far short of high-level goals National ambitions to lower emissions have grown significantly in recent years, with many new countries signing onto methane commitments. High-level methane pledges now cover around 80% of global fossil fuel production, up from around 50% in 2021. This includes the Global Methane Pledge (GMP), which today includes more than 150 countries and covers more than 50% of emissions from human activity worldwide. Launched in 2021 at the 26th United Nations Climate Change Conference (COP26), the GMP commits participating countries to…

World Energy Employment 2025
The World Energy Employment (WEE) report series provides comprehensive tracking and analysis of the global energy workforce, including estimates of its size and distribution across regions, sectors, and technologies. It also assesses how energy labour requirements evolve to 2035 across all IEA scenarios.The WEE 2025 – the fourth edition – examines how skilled labour needs and shortages have changed since the series first highlighted these issues in 2022, and explores their implications for education and training systems, wages, policy, and the global buildout of energy infrastructure. This year’s report introduces, for the first time, detailed occupation-level estimates that offer…

Global Energy and Climate Model Policies
Policies database Underpinning the scenario analysis of the GEC Model, an extensive effort is made to update and expand the list of energy and climate-related policies and measures that feed into our modelling. Assumptions about government policies are critical to this analysis and are the main reason for the differences in outcomes across the scenarios. A summary of some of the key policy targets and measures for different sectors by selected countries and regions can be found in the Annex B of WEO-2025.Although all care has been taken to ensure accuracy, completeness and clarity of content in…

Southeast Asia Energy Outlook 2026 Energy in Southeast Asia
Southeast Asia is becoming an increasingly important part of the global energy system. The region accounts for 9% of the world’s population and 4% of its GDP. Energy use has risen sharply since 2015, supported by industrialisation, urbanisation, rising incomes and expanding mobility needs. This growth has helped underpin economic development and wider access to modern energy, but it has also increased exposure to global fuel markets and added to emissions. The current Middle East crisis has tested Southeast Asia’s energy security and affordability, exposing the limits of short-term responses. The region was heavily exposed to Middle…

Energy Efficiency 2024 What is required to scale up energy efficiency investments by 2030?
Governments should develop comprehensive investment strategies tailored to their unique circumstances In the NZE Scenario, investment in end uses such as more efficient buildings, transportation and industry triples from around USD 650 billion per year today to about USD 1.9 trillion per year by 2030. The IEA highlights in its Taking Stock to Taking Action report how a comprehensive approach to energy efficiency action is the most effective way to accelerate progress, with an array of available diverse measures tailored to each country’s specific circumstances. In emerging economies, where many people are getting access to new modern accommodation and appliances for…

Manufacturing and Trade Model
The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy…
