Global air conditioning demand projected to surge amid rising temperatures

Global demand for air conditioning is projected to rise significantly as temperatures increase. The International Energy Agency predicts that the number of air conditioning units worldwide could grow from approximately 2.5 billion in 2026 to 5.6 billion by 2050. This surge is expected to be driven largely by regions where AC ownership is currently low, such as Indonesia and India.

In the United States, research from the Harvard Joint Center for Housing Studies indicates that over 13 million households experienced uncomfortably hot indoor temperatures in 2023, even when they possessed cooling equipment. Common issues included system breakdowns, poor insulation, and aging hardware. Data from the Federal Reserve Bank of Philadelphia suggests that nearly 8 million U.S. households faced cooling-related repairs in 2023, with an average cost of $2,200 per unit.

The growing need for cooling presents a challenge for global energy systems. Experts note that meeting this demand sustainably will require a significant increase in renewable energy to prevent exacerbating global warming through increased electricity consumption, particularly during peak demand periods.
