Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…

Critical Mineral Traceability for Energy and Economic Security
Amid rising risks linked to the high concentration of critical mineral supply chains, the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for policymakers seeking to create diversified and responsible supply chains.This report provides insights from a first-of-its kind survey on traceability conducted by the IEA and OECD. More than 80 respondent companies active across supply chains of the six focus minerals (copper, lithium, nickel, cobalt, graphite and rare earth elements) provided results between October and December 2025. Drawing on…

Efficient Grid-Interactive Buildings in India
Status and opportunities This report assesses the opportunities for efficient grid-interactive buildings (EGIBs) to support India’s clean energy transition. EGIBs unite energy efficiency, smart digital technologies and demand-side flexibility, allowing them to optimise energy use, shift or reduce peak demand and better align consumption with renewable energy generation.The buildings sector is central to clean energy transitions in a context where rapidly increasing electricity demand is driven by cooling and appliance use, 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…

Mozambique 2024
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 Mozambique and the IEA. It draws on the IEA’s extensive…

Manufacturing and Trade Model
The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy…

Energy Efficiency 2025
Market Report Energy Efficiency 2025 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, investment, employment and policy. The report provides sector-specific analysis on industry, buildings, appliances and transport and explores system-wide themes such as emissions reductions, energy security, affordability and competitiveness. This report is launched in parallel with an update to the IEA Energy Efficiency Progress Tracker, which can be accessed through the IEA website.

Designing Energy Efficiency Policies to Enhance Affordability
Examples from G7 countries Energy affordability has emerged as a critical concern in the context of rising global energy prices and growing inequality in energy access. Lower-income households spend a significantly higher share of their income on energy than wealthier households, leaving them exposed to price shocks and especially vulnerable when energy prices increase. Energy efficiency can play a key role in delivering lower energy bills, reducing emissions, and enhancing resilience. However, ensuring that all households benefit requires targeted, inclusive policy design.This issue was a central focus of an IEA workshop held in January 2025 with G7 country…

Universal Access to Clean Cooking in Africa
Progress update and roadmap for implementation Clean cooking access is a defining challenge for Africa’s prosperity. While the number of people without access to clean cooking has halved globally since 2010, the number in sub-Saharan Africa continues to rise. This harms health, economic development, and the environment – contributing to 815 000 premature deaths annually and significant deforestation.In a new report, Universal Access to Clean Cooking in Africa: Progress update and roadmap to implementation, the International Energy Agency (IEA) provides an updated picture of where things stand today, where efforts are gaining ground, and where urgent action is…

Outlook for Biogas and Biomethane
A global geospatial assessment Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential…
