While the most energy-efficient way to dry freshly laundered clothing is to line dry it, it's not the most practical for all of us -- especially as it gets colder. If you do use the dryer, one way to speed up the drying process is to throw in the towel -- literally. By adding a dry bath towel, excess moisture is absorbed from the wet clothes. This also helps freshen stale-smelling towels that may have been in the linen closet for too long. Also, be sure the lint trap is clean: A clogged trap isn't just a fire hazard, it also prevents air from circulating.
