Finally, the local cost of electricity influences the general cost of running your air conditioner. This is something you have no control over, however, you can control your own cost by saving energy.

Here is a general look at the difference of running an air conditioner vs. running a Ceiling or oscillating fan, at medium speed.

Running a central air conditioner that is three ton (and of average efficiency) for 8 hours per day for 15 days per month, with the average rate per kWh (kilowatt per hour) being 0.17, the average cost per month for the air conditioner alone will be $97.92. Amazing isn't it? This does not even include washer, dryer, lights, refrigerator, or stove, only the air conditioner.

On the other hand, running a ceiling fan or oscillating fan at medium speed, for 8 hours per day, for a full 30 days, at an average rate per kWh of 0.035 is only $1.43. With this comparison you could run 68 ? fans for a full month before you would reach the cost of the central air conditioning unit.
