…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 region and worldwide. This year the forecast period has been expanded to five years, 2026-2030, compared with the previous three-year…

Grid investments
…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 energy.Energy efficiency measures can typically be deployed in under a year, while generation and transmission projects require between one and seven years to build on average, depending on technology, or over a decade for nuclear…

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
…and clean cooking can lead to higher comfort and quality of life. As a result, the energy savings of efficiency measures can be initially lower than expected. In India, time-saving appliance ownership, such as of washing machines or refrigerators, is associated with a 15% increase of employment among women and an increased school attendance by older children.As people gain access to electricity, they acquire new equipment, often starting with light bulbs, followed by televisions, and finally fans, particularly in hot locations. As available power increases and electricity becomes more reliable, refrigerators are installed as well. For many products…

Ensuring a Skilled Renewable Energy and Energy Efficiency Workforce
…and energy efficiency. It highlights the increased demand for skilled workers in these sectors and the need to address skilled labour shortages. The report identifies barriers which are currently hindering energy education and training. It also discusses policy measures aimed at attracting more people to the renewable energy and energy efficiency sectors and providing them with the necessary training. The report includes new IEA analysis on online job postings in renewable energy and energy efficiency, and IEA modelling on energy employment from 2024 as the last full year of data available at the time of publication. The analysis also draws…

Heat Pump Taxonomy
A common framework for heat pumps classification and data Heat pumps are a cornerstone technology for achieving secure, affordable and sustainable heating. They have become one of the most common heating technologies and have the potential to impact significantly future trends for energy consumption in buildings and beyond.Tracking and analysing the pace of heat pump deployment compared to that of conventional heating technologies is essential for understanding future needs with regards to energy demand, investments in electricity infrastructure and fuel supply.Despite their growing importance, data on heat pump installations, as well as on their performance and cost, remain…

…is putting additional strains on power grids and leading to new peak demand records and resiliency challenges. In 2019, 1°C in outdoor temperature increase was associated with a 5 GW increase in peak electricity demand; with rising air‑conditioner ownership and increasing temperatures, this value rose to 7 GW in 2024 and could further rise to 12 GW in 2030 without further efficiency action. If India were to experience similar heatwaves as in recent years – with temperature anomalies of over 4°C – the additional peak load would amount to 47 GW. However, if all new air conditioners in India were highly efficient (e.g. through increased…

Global Energy and Climate Model
…energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global Energy and Climate Model…

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…
