Energy Efficiency 2023 INTERNATIONAL ENERGY AGENCY The IEA examines the full spectrum of energy issues including oil, gas and coal supply and demand, renewable energy technologies, electricity markets, energy efficiency, access to energy, demand side management and much more. Through its work, the IEA advocates policies that will enhance the reliability, affordability and sustainability of energy in its 31 member countries, 13 association countries and beyond.

It explores recent trends in energy intensity, demand and efficiency-related investment, policy and technology. This tenth edition of the market report also features a new spotlight section, focused on key issues facing policy makers this year. In particular, the report details what is entailed with the proposed global target to double energy efficiency progress and what will be gained by achieving it. PAGE | 3 I EA. CC BY 4.0. This year’s report comes amidst the ongoing effects of the energy and climate crises in what is expected to be the hottest year on record. In this context, 2023 global energy efficiency progress, as measured by primary energy intensity, is expected to be slightly below the long-term trend in a slow down from 2022. However, the report makes clear that a profound transformation is underway in energy efficiency and clean energy more broadly, with many governments introducing new, or strengthening existing, policies and energy-saving programmes. These policies are leading to faster deployment of efficient technologies and are contributing towards an expected peaking of fossil fuel demand in the coming years. Energy Efficiency 2023 Acknowledgements Acknowledgements Energy Efficiency 2023 was prepared by the Energy Efficiency and Inclusive Transitions Office (EEIT) in the Directorate of Energy Markets and Security (EMS) and in collaboration with other directorates of the International Energy Agency (IEA). The report was designed and directed by Nicholas Howarth, Energy Analyst (EEIT). Other lead authors were Lucas Boehlé, Federico Callioni, Hadrien Loyant, Jack Miller and Fabian Voswinkel. Diane Munro edited the report. Principal authors (in alphabetical order) were: Clara Camarasa (cooling), Conor Gask (China and sector analysis), Pauline Henriot (systems efficiency), Kristina Klimovich (PACE and behaviour), Natalie Kauf (Southeast Asia, systems efficiency), Simrat Kaur (India), Silvia Laera (systems efficiency), Emma Mooney (behaviour, industry and EEOs), Alison Pridmore (transport), Sungjin Oh (government spending and policy updates), Josh Oxby (employment), Ksenia Petrichenko (buildings and systems efficiency), Cornelia Schenk (investment, India), and Brendan Reidenbach (investment in digital).
