Of course the best solution to saving energy on clothes drying is to hang them outside. HOWEVER: I have been informed at a conference that the same is not true for hanging them indoors. For those of us that need to heat our homes in the winter/cold seasons, drying clothes inside which adds extra humidity into the indoor air will actually cost more money and use more energy than drying them in a dryer. The reason for this is that more humid air is harder to heat, as you are heating both the air and the humidity. Your furnace will have to use a lot more energy to heat your house to the point where your clothes will dry inside than what you would have used if you had put your clothes in the dryer, which presumably has an air tube to send the humid air out into the outdoors, so that this harder-to-heat humid air does not enter your home and require additional heat from your central heating.
Feel free to correct me if you feel that I am wrong.
