The cost of using a hair dryer for one year can be estimated by calculating the power consumption in kilowatt-hours (kWh) based on the dryer’s wattage and the average usage time. For instance, a typical hair dryer operates at around 1,500 watts. If used for 30 minutes daily, this results in approximately 91.25 hours of use annually, leading to a total consumption of about 1,375 kWh per year. With an average electricity cost of $0.12 per kWh, the annual cost of using a hair dryer would be approximately $165.
