Country-level energy demand for cooling has increased over the past two decades

E. Scoccimarro, O. Cattaneo, et al.

Discover how energy demand for cooling has transformed over the past two decades, revealing alarming trends in cooling degree days (CDDs) worldwide. Conducted by a team from the Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC) and the International Energy Agency (IEA), this research highlights the pressing need for sustainable cooling solutions, especially in emerging countries where humidity amplifies energy use.

Abstract
This paper investigates the changes in country-level energy demand for cooling over the past two decades (2000-2021). Using a new database jointly generated by CMCC and IEA, the study analyzes cooling degree days (CDDs), considering population weighting and humidity. Results show a general increase in CDDs worldwide, leading to higher energy consumption for cooling. The study also examines the temporal clustering of CDDs, revealing that intense CDD periods tend to cluster, particularly in emerging countries like India, Cambodia, Thailand, and Vietnam, where the impact of humidity is more pronounced.
