About this report
Energy Efficiency 2022 is the IEA’s primary annual analysis on global developments in energy efficiency markets and policy. It explores recent trends in energy intensity, demand and efficiency-related investment, innovation, policy and technology while also discussing key questions facing policy makers.
This year record-high consumer energy bills and securing reliable access to supply are urgent political and economic imperatives for almost all governments. In response to the energy crisis countries are prioritising energy efficiency action due to its ability to simultaneously meet affordability, supply security and climate goals.
While efficiency investment has recently been increasing to reach new record levels, the pace of global energy intensity improvements had noticeably slowed in the second half of the last decade and virtually stalled during the first two years of Covid-19. With efforts to better manage energy consumption as a result of the crisis increasing the rate of improvement once more, the question as to whether 2022 will see a sustained efficiency turning point, and what more can be done, are key themes of this year’s report.
