According to the Saving Electricity website, a medium-sized window air conditioner consumes approximately 900 watts of electricity hourly. A floor fan, on the other hand, generally only uses 100 watts per hour. Given these figures, it takes nine fans to equal the energy used by a single room air conditioner.
