Compare the cost of running a fan versus an air conditioner.
A fan moves air for a fraction of the wattage an air conditioner draws. Multiplying each by the same runtime and rate shows how much cheaper fan-only cooling is. Using a fan to circulate AC-cooled air (or instead of AC on mild days) is one of the simplest ways to cut summer electricity.
