With electricity at 15 cents per kilowatt hour, a dryer costs 33 cents to run for one-half hour. The amount increases if the electricity rate is higher. For example, at 25 cents per kWh, the expense for the load is 55 cents.
At 15 cents per kWh, if one load of laundry is dried for one-half hour each day, the yearly cost is $120. This increases to $200 if the cost of electricity is 25 cents per kWh. Hanging some laundry outside or on indoor racks helps to cut this expense. Also, in some areas, gas is cheaper than electricity, so a gas dryer is more economical. In addition, cleaning the lint filter increases a dryer's efficiency, which reduces costs.
