Understanding Energy Consumption of Cooling Devices

Joe Hari discusses the energy consumption of air conditioners during summer and the associated costs. He explains that running a standard 1200-watt AC for 12 hours daily from June to September can cost around $120 per month in New York. To reduce costs, he suggests using a 100-watt box fan or a 75-watt ceiling fan, which are more energy-efficient alternatives. Alternating between AC and fans can help circulate cold air and lower energy bills.
