Energy savings
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy savings. Why is energy efficiency important for energy savings? Energy efficiency measures reduce the amount of energy required to fuel and grow our economies. In economies where energy demand is set to grow significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors…

Indicators Handbook for Just and Inclusive Energy Transitions
Global Commission on People-Centred Clean Energy Transitions: Designing for Fairness The Indicators Handbook is based on the voluntary G20 Principles for Just and Inclusive Transitions, endorsed by G20 leaders in November 2024. The principles, which reflect varying perspectives, contexts and experiences, form a framework for approaching transitions that maximises benefits and mitigates the risk of unintended consequences. Designed as a technical resource, the Indicators Handbook provides guidance for governments and other stakeholders on identifying relevant indicators as a first step towards tracking policy design and implementation in line with the G20 Principles for Just and Inclusive Transitions. The Handbook…

Southeast Asia Indicators Handbook for Just and Inclusive Transitions
Energy demand in Southeast Asia is growing, driven by rapidly growing population and economies, industrialisation and urbanisation. Many countries in the region have set out their own national decarbonisation targets and clean energy transitions commitments.Clean energy transitions in the region present unique opportunities to deliver broad socio-economic benefits, beyond emissions reductions, such as the creation of new decent jobs, economic diversification, reduced energy poverty and improved air quality. Tracking these benefits can help ensure that all parts of society benefit from these changes.In 2024, G20 leaders endorsed ten voluntary G20 Principles for Just and Inclusive Energy Transitions…

Copper
Outlook for key energy transition minerals This report provides an outlook for demand and supply for key energy minerals including copper, lithium, nickel, cobalt, graphite and rare earth elements. Demand projections encompass both key energy technologies and other uses under different IEA Scenarios. Supply projections are based on a detailed review of all announced projects. They show how today's geographical concentration evolves over time, for both mining and refining and how expected supply compares with primary supply requirements.

Korea 2025
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Korea and the IEA. It draws on the IEA’s extensive…

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…

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…
