Economic growth
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores economic growth. Why is energy efficiency important for economic growth? Energy efficiency allows countries to generate more economic activity using the same amount of energy. It is also linked to increased labour productivity and other economic benefits. Key facts Compared with 2000, today’s global economy produces 36% more GDP per unit of energy. Energy efficiency progress over the last 20 years means that close to an extra USD 50 trillion can today be produced using the same amount of energy. This energy efficiency bonus is equivalent to…

Ensuring a Strong Labour Dimension for Just and Inclusive Energy Transitions
IEA Clean Energy Labour Council Workers play a critical role in the global energy system, providing key services across many areas of the energy sector. To give a greater voice to the labour perspective in energy and climate policy discussions, the IEA Executive Director, Dr. Fatih Birol, convened the Clean Energy Labour Council in 2022. The Labour Council brings together representatives of the world’s most important national trade unions and trade union confederations, as well as prominent thinkers on the topic, to foster engagement between the IEA, energy policy makers, and the labour movement.The IEA Clean Energy Labour…

Stepping Up the Value Chain in Africa
Minerals, materials and manufacturing This report explores key opportunities for African countries to step up the value chain in the growing global market for energy technologies, identifying opportunities beyond a role centred around extraction and mining to one more focused on mineral beneficiation, material production and technology manufacturing. These opportunities would enable Africa to retain a greater share of the economic value generated across energy technology supply chains, and would simultaneously contribute to global efforts to enhance supply chain diversification and resilience.The economic benefits of the new energy economy are currently distributed very unevenly. Emerging markets and developing economies…

The Implications of Oil and Gas Field Decline Rates
Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new…

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…

Clean Energy Technology Supply Chain Data
Challenges and potential solutions Energy security in the Age of Electricity is inextricably linked to securing the supply chains for clean energy technologies and the equipment and materials used to manufacture them. As countries continue to pursue energy transitions and to direct investments to these technologies, guided by industrial strategies, a detailed understanding of their supply chains has an essential role to play. The availability of good-quality, timely data is crucial to gaining this understanding and to identifying and addressing supply chain vulnerabilities.This report is provided as an input to the discussions taking place as part of the…
