Adoption of air conditioning is increasing globally, leading to peaks in electricity consumption and related environmental concerns. Compiling recent data on population and temperature, this study ranks 219 countries and 1,692 cities based on a measure of cooling demand to improve our understanding of future trends.

Air conditioning adoption is increasing dramatically worldwide as incomes rise and average temperatures go up. Using daily temperature data from 14,500 weather stations, we rank 219 countries and 1,692 cities based on a widely used measure of cooling demand called total cooling degree day exposure. India, China, Indonesia, Nigeria, Pakistan, Brazil, Bangladesh and the Philippines all have more total cooling degree day exposure than the United States-a country that uses 400 terawatt-hours of electricity annually for air conditioning.
