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.
