What could I save by hanging laundry outside instead of using a gas dryer for 14 loads a week?

The savings from hanging laundry outside instead of using a gas dryer can be calculated by determining the price per load of the gas and subtracting the costs of air drying. For a dryer that uses 3.3 kilowatt hours of gas, the weekly savings for 14 loads would equal $5.04.

While the exact cost of a load of laundry varies based on the price of gas, a 45-minute load at the price of 11 cents per kilowatt hour equals $0.36 per load. In comparison, the price of hanging laundry includes the one-time purchase of reusable clothing lines and pins, and increased labor time can decrease the estimated savings.
