Abstract
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.
