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…

Energy Efficiency Policy Toolkit
…for Energy Efficiency to help governments deploy coordinated policy approaches across these three pillars. The Energy Efficiency Policy Toolkit was subsequently developed to also integrate concrete, sector-specific guidance, along with best practices from around the world.Ten strategic principlesBased on the IEA’s analysis of best practices and the work of the Global Commission for Urgent Action on Energy Efficiency, the following strategic principles can help guide policymakers to enhance and expand their energy efficiency policies and programmes, and to accelerate energy efficiency gains through new and stronger policy.Prioritise cross-cutting energy efficiency action for its economic, social and environmental benefits…

Energy Efficiency in China’s Buildings Sector
…progress in achieving them. Regulation for new buildings in China, such as building codes, is relatively strong. However, as the rate of construction is slowing, policy priorities are shifting towards retrofitting existing buildings. Here, the IEA estimates that through strong policy action and best-in-class technology, China could reduce energy consumption by up to 65% in buildings constructed between 1995 and 2010, representing energy savings of over 8 000 Petajoules.The report includes examples from across China and the world on leading regulatory instruments, financial incentives, and information-based tools that can drive energy efficiency in the buildings sector.

Efficient Grid-Interactive Buildings in India
…and the share of variable renewable energy in electricity generation is continuously growing. Without targeted action, unmanaged peak loads and variable supply could jeopardise grid stability and increase system costs. EGIBs offer an important solution for optimising electricity use, reducing peak demand and enhancing system flexibility.Applying a structured framework, this report assesses India’s policy landscape and opportunities across efficiency, decarbonisation, smartness, resilience, materials and building-to-grid interaction. It concludes with recommendations for a comprehensive policy package that encompasses regulations, incentives and information. Scaling up the adoption of efficient grid-interactive buildings would enable India to align its…

Best Practices and Insights to Expand Clean Energy Access and Adoption
…follow low-emissions practices and are resilient and inclusive. It draws on international evidence, including workshop discussions, IEA analysis and a wide range of global case studies, to identify key impacts and lessons learned from evidence and practice. It highlights how behaviour change is most effective when supported by coherent policy frameworks, targeted measures addressing affordability and structural changes across sectors such as buildings, transport and appliances. By identifying good practices and practical insights, the report provides guidance to support policymakers design inclusive strategies that enable sustainable lifestyles and ensure the benefits of the energy transition are shared by all.

Overview graphic: key technology trends for EVs
…control. Sensors and chips integrate well with the stable, high-voltage power supply of EV batteries. At the same time, the benefits of AI and increased computing power are not exclusive to EVs. AI‑enabled energy management systems are increasingly used to optimise hybrid vehicles, and AI techniques are accelerating the design, testing and optimisation of all vehicles.Finally, technologies enabling EV-grid integration are becoming increasingly available, allowing EVs to play a larger role in the energy system and improving their value proposition. With the rollout of smart and bidirectional charging, EV owners can reduce charging costs and, in some cases…

Ensuring a Skilled Renewable Energy and Energy Efficiency Workforce
…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 from stakeholder input from two in-person Future of Energy Skills workshops co-ordinated by the IEA and the European…

Renewables in District Energy
…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 pumps and thermal energy storage…

Household Energy Affordability
Energy is one of the top expenses for millions of households, making energy affordability an important policy concern for governments. The impacts of the global energy crisis on consumer prices have been significantly felt in household budgets. Despite coming down from their peak in 2022, prices remain elevated compared to pre-crisis levels and households continue to grapple with higher living costs.This report sets out to identify key trends that are shaping the state of energy affordability around the world today. It explores how system drivers and household energy consumption influence the makeup of energy bills and opens a…
