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…

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.

Energy Efficiency Policy Toolkit
The Energy Efficiency Policy Toolkit is an interactive online tool that has been updated and expanded ahead of the 11th Annual Global Conference on Energy Efficiency in Montreal, Canada. It aims to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information and incentives. It also features a wide range of case studies, offering practical insights into the successful implementation of energy efficiency policies across diverse national and sectoral contexts.The Toolkit builds on earlier IEA work to advance energy efficiency policy. In 2022, the IEA introduced Policy Packages for Energy…

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…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

Competitiveness
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores competitiveness. Why is energy efficiency important for competitiveness? Increasing energy efficiency can improve competitiveness at both the firm level – by reducing costs, improving operations and increasing product value – and at the country level, by reducing the amount of energy required to produce economic output. Key facts Today the world’s industries produce nearly 20% more value added with a given amount of energy, compared with two decades ago. In the industrial sector, energy management can lead to more than 10% in annual energy cost savings within…

National Climate Resilience Assessment for Algeria
Algeria’s energy system already faces significant disruption due to extreme weather events. Critical infrastructure has been impacted in recent years by flash floods, drought-induced wildfires and heatwaves. With the climate projected to warm more rapidly than the global average, these risks are likely to intensify. Proactive measures to enhance the resilience of Algeria’s energy system could offer substantial benefits.Algeria has experienced significant warming, averaging 0.49 °C per decade from 2000 to 2023 and exceeding the global average of 0.37 °C per decade. Temperatures are expected to rise further, reaching up to 5.6 °C above pre‑industrial levels…

Autonomous vehicles
GEVO 2026 - Chapter 8 Progress in AI and computing power is disproportionately benefiting EVs, particularly for automated driving and integrated vehicle control. Sensors and chips integrate well with the stable, high-voltage power supply of EV batteries. Electric vehicles lead in automation and advanced driver assistance Driving automation is at the forefront of software developments for cars today. While fully autonomous cars (Level 5 automation)) are not currently in sight, electric driverless taxis (Level 4) are already operating commercially in more than 20 cities worldwide. Moreover, automated driving systems are not limited to self-driving cars – they are also rapidly gaining…
