The price of electricity is usually quoted per kilowatt-hour. If your hair dryer uses 2,000 watts for 30 minutes, that is one kilowatt-hour.

So take the wattage rating of your hair dryer and divide by 1000 to get kilowatts. You specified 30 minutes, which is 0.5 hours; multiply the kilowatts by the hours to get kilowatt-hours. Then multiply the price per kilowatt-hour of your electricity to get the total cost.

For example: 1500-watt hair dryer for 30 minutes at $0.12/kW-h

1500 watts ÷ 1000 = 1.5 kilowatts

30 minutes = 0.5 hours

1.5 kilowatts x 0.5 hours = 0.75 kW-h

0.75 kW-h x $0.12/kW-h = $0.09

To calculate the cost, first convert the hair dryer's power consumption to kilowatts: 1500 watts = 1.5 kW. Then, calculate the daily energy consumption: 1.5 kW * 0.5 hours = 0.75 kWh. Finally, determine the total cost: 0.75 kWh/day * 30 days * $0.12/kWh = $3.60.

How much water does a tumble dryer use?

A standard tumble dryer typically does not use water during the drying process. Instead, it releases moisture from the clothes into the surrounding air, which is then vented outside through a dryer vent. Some newer models have steam settings that may use a small amount of water for steam refresh cycles.
