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…

Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…

Grid investments
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores grid investments. Why is energy efficiency important for grid investments? As we enter the Age of Electricity, global electricity demand is rising 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 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…

Breakthrough Agenda Report 2025
Accelerating sector transitions through stronger International collaboration Breakthrough Agenda Report 2024 Since its launch at COP 26, the Breakthrough Agenda has become established as an annual collaborative process centred around the Conference of the Parties (COP) meetings of the United Nations Framework Convention on Climate Change (UNFCCC). It is currently supported by over 60 countries representing over 80% of global GDP, and by over 150 initiatives working to enhance collaboration within major emitting sectors. Countries can endorse Breakthrough goals to make clean technologies and sustainable practices more affordable, accessible and attractive than their alternatives by 2030 in the power, road transport…

Scaling Up Transition Finance
Scaling Up
Transition
Finance Actions by emissions-intensive sectors, companies and countries are crucial to placing the world on a sustainable pathway. Yet investments that could deliver meaningful reductions in their environmental footprint often do not receive sufficient financial support. Currently, finance is drawn heavily to certain “green” assets and activities. While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost-competitive. This is where transition finance comes in: it can help emissions-intensive countries, companies and sectors shift over time towards…

Global Methane Tracker 2025
Methane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, and rapid and sustained reductions in methane emissions are key to limiting near-term global warming and improving air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for more than 35% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker is an essential tool for raising awareness about methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents our latest…

What Next for the Global Car Industry
An Energy Technology Perspectives Special Report The global car industry has operated under relatively stable conditions for decades. The world’s largest car manufacturers are based in the European Union, Korea, Japan and the United States, and – more recently – in China, and the car industry is a major contributor to the economy in these countries. The strength of many of these car makers is built on decades at the forefront of technological innovation around the internal combustion engine (ICE), as well as highly integrated and optimised supply chains that allow for vehicles and their components to be produced at low…

Gaining an Edge
The Role of Energy Efficiency in Enhancing Competitiveness Energy efficiency delivers more than energy savings and emission reductions – it can also improve the competitiveness of countries and firms. From increased profitability to job creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.The report analyses historical progress in industrial energy efficiency and its role in enhancing industrial competitiveness. It includes comparisons of firm-level energy efficiency, identifying performance gaps and opportunities for further improvement. Drawing…

Financing Electricity Access in Africa
Access to electricity is a cornerstone for economic development, poverty reduction and social equity. However, almost 600 million people in Africa lack access to electricity today, with progress falling far behind targets set by both African governments and the international community. Reaching universal electricity access will require a rapid scale-up of investment and financing to USD 15 billion per year, enabling the expansion of generation capacity, grid networks and decentralised solutions while ensuring that progress remains inclusive and sustainable.In a new flagship report, Financing Electricity Access in Africa, the International Energy Agency (IEA) undertakes its authoritative energy analysis…
