I think hanging wet clothes up inside can cause damp and mould. Fair enough if you can hang it next to a boiler or radiator and have the window open. I use a tumble dryer and the cost is better than seeing wet clothes hung up which I just don't like. In the warmer weather the clothes always go on the washing line outside. Obviously different things work for different people.
I think this is where the dehumidifier comes into its own. Dries the clothes and gets rid of damp. Dry air needs less energy to heat so they are can be " energy neutral "
