Ceiling Fan
A ceiling fan can be a good alternative to air conditioning in areas where it doesn’t get insanely hot. At 35 watts of consumption, leaving your ceiling fan on all day will cost you about 8 cents, but shutting it off when you’re not in the room will cost even less. A reversible fan is the best choice since it can pull warm air up out of the room in summer and push it down into the room in winter.
