My kids gave me a "kill a watt" for Christmas. This is a neat little gadget that you plug into an outlet and then plug into it an appliance to see how much power it consumes.
I used it on my washer and gas dryer. The washer used .26 kwh to wash a load and the gad dryer used .33 kwh.
My Homeowners association does not permit the drying of laundry outside so I am now drying it in the unused guest room. The space is limited so I occasionally have to wash an extra load, doing slightly smaller loads and using the water saver feature so as not to waste water.
Air drying saves not only gas but a surprising amount of electricity. It all so gives me a little extra exercise.
