Residential air conditioning uses about 2,000 kWh of electricity each year per U.S. household. It represents 12% of total residential electricity use, yet global cooling energy demand has climbed to about 2,000 TWh after doubling since 2000. Inefficient systems waste around 1.2 trillion kWh annually, while average new U.S. ACs reach a SEER rating of 14.3 in 2023.
