Energy Efficiency 2023

INTERNATIONAL ENERGYAGENCY The IEA examines thefull spectrumof energy issuesincluding oil, gas andcoal supply anddemand, renewableenergy technologies,electricity markets,energy efficiency,access to energy,demand sidemanagement andmuch more. Throughits work, the IEAadvocates policies thatwill enhance thereliability, affordabilityand sustainability ofenergy in its31member countries,13associationcountries and beyond.

It explores recent trends inenergyintensity,demand and efficiency-related investment,policy andtechnology. This tenth edition of the market report also features a new spotlightsection, focused on key issues facing policy makers this year. In particular, thereport details what is entailed with the proposed global target to double energyefficiency progress and what will be gained by achieving it. This year’s report comes amidst the ongoing effects of the energy and climatecrises in what is expected to be the hottest year on record. In this context, 2023global energy efficiency progress, as measured by primary energy intensity, isexpected 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 inenergyefficiency and clean energy more broadly,with many governmentsintroducingnew,or strengthening existing,policies and energy-savingprogrammes.These policies are leading to faster deployment of efficienttechnologies and are contributing towards an expected peaking of fossil fueldemand in the coming years. Acknowledgements Energy Efficiency 2023 was prepared by the Energy Efficiency and InclusiveTransitions 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), ConorGask (China and sector analysis), Pauline Henriot (systems efficiency), KristinaKlimovich(PACE and behaviour),Natalie Kauf(Southeast Asia,systemsefficiency), 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), KseniaPetrichenko (buildings and systems efficiency), Cornelia Schenk (investment,India), and Brendan Reidenbach (investment in digital). Further support and inputwere provided by Juliette Denis-Senez Jappe, Caroline Fedrine, Lisa MarieGrenier, Andika Hermawan, Yujun Huang and Orestis Karampinis. Mitsidi Projetosand Ian Hamilton also provided much valued analytical support. Lead authors for special spotlight sections were as follows: Lucas Boehlé andFederico Callioni (energy intensity progress); Hadrien Loyant, Jack Miller andFabian Voswinkel (doubling efficiency progress); Clara Camarasa, Arnau RisquezMartin and Fabian Voswinkel (cooling in the hottest year on record); PaulineHenriot, Silvia Laera, Natalie Kauf and Arnau Risquez Martin (benefits of systemsefficiency); Lucas Boehlé, Ian Hamilton, Hadrien Loyant and Ksenia Petrichenko(gas and residential heating); Simrat Kaur, Cornelia Schenk, and Arnau RisquezMartin (cooling in India). Brian Motherway, Head of EEIT provided overall strategic direction to the report,along with Vida Rozite, Energy Analyst. Melanie Slade, Senior ProgrammeManager, also gave expert advice and management support to the report. Keisuke Sadamori, Director of Energy Markets and Security (EMS) providedimportantexpert guidance and advice.Valuable comments,feedback andguidance were provided by other senior managers within the IEA and in particular,Toril Bosoni, Laura Cozzi, Dan Dorner, Paolo Frankl, Tim Gould, Timur Gül,Dennis Hesseling and Nick Johnstone. This year’s market report benefited from a special analysis conducted by EMScolleagues Joel Couse and Louis Chambeau drawing on fuel reports from acrossthe directorate. Par
