Global Energy Review 2026 Technology: Solar PV and wind
In 2025, global annual renewable capacity additions increased by 16%, reaching 800 GW despite challenges linked to supply chain strains, grid connection delays, financial pressures and policy shifts. This marked the 23rd consecutive year that renewables set new expansion records. Solar PV accounted for more than three-quarters of new renewable capacity additions worldwide, followed by wind (20%). The remaining share was made up by hydropower, bioenergy, geothermal, concentrating solar power and marine energy. Solar PV capacity additions in 2025 rose by around 12%, surpassing 600 GW for the first time. This expansion brought cumulative solar PV capacity to around…

IEA Guide to Reporting Energy Technology RD&D Budgets
This manual, developed by the International Energy Agency (IEA), provides comprehensive guidance for national experts responsible for reporting energy technology research, development, and demonstration (RD&D) budgets. It outlines the methodology and classification system used to collect and structure RD&D data across IEA member countries, ensuring consistency and comparability. The manual is divided into two main sections: fundamentals of RD&D budget reporting and a detailed classification of energy technologies. It defines RD&D in alignment with the OECD Frascati Manual and clarifies the scope of public and private sector reporting. It also provides instructions for completing the IEA…

Coal Mid-Year Update 2025 Trade
Global coal trade reached an all-time high in 2024 Global coal trade reached a new all-time high in 2024, with total volumes estimated to be 1.55 Bt, surpassing the 1.5 Bt mark for the first time. Thermal coal trade rose by 28 Mt to reach 1 180 Mt. This growth was primarily driven by strong import demand in Asia, especially from China. The country experienced growth in imports, with coal imports reaching new highs. Imports increased by 14% up to 548 Mt, resulting in total annual imports surpassing 500 Mt for the first time. This volume is more than…

Global Hydrogen Review 2025 Southeast Asia
Highlights Hydrogen demand in Southeast Asia reached 4 Mt in 2024, almost 4% of the global total. Hydrogen production accounted for about 8% of the regional gas supply and 1% of regional CO2 emissions. Indonesia represents over a third of regional demand, followed by Malaysia (22%), Viet Nam (15%) and Singapore (12%). Nearly half of all demand is for ammonia, of which two-thirds comes from Indonesia alone. Refining accounts for a third of demand, with 40% located in Singapore; methanol represents the remaining 20%, with 69% in Malaysia. The region currently exports ammonia (15% of production) and imports methanol.Indonesia, Lao…

Renewables in District Energy
This report examines how renewables can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat…

Affordability
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores affordability. Why is energy efficiency important for affordability? Energy efficiency measures can reduce energy bills for households, decrease energy poverty, and make access to energy services more affordable. Key facts Energy efficiency measures can reduce average household energy bills in advanced economies by up to one-third. In emerging economies, they can also improve access to energy services. For many products, such as refrigerators, highly efficient models use less than half of the energy of inefficient models. A best-in-class model can save up to…

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 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…

Southeast Asia Energy Outlook 2026 Southeast Asia’s energy challenges and emerging opportunities
The Middle East crisis has exposed Southeast Asia’s vulnerability to fossil fuel supply shocks and the limits of short-term emergency responses. Before the crisis, around 60% of the region’s crude oil imports and a third of its gas imports came from the Middle East, while 45% of its oil product supply was linked to Middle Eastern crude once refinery feedstocks and indirect product trade are included. Governments have responded with demand-reduction measures, tax relief, subsidies, price caps and targeted support to cushion households and firms from higher fuel and electricity costs. However, these measures add to…

Household Energy Affordability: Data and Indicators
A methodological framework for national monitoring Effective policy requires robust monitoring of household energy affordability, yet no unified methodological approach currently exists. The upcoming IEA report Household Energy Affordability: Data and Indicators, to be published in July, addresses this gap. This executive summary presents its key elements, including a robust methodological framework structured around dimensions, indicators and data to support policy discussions and national monitoring efforts.
