The Cost of Air Conditioning Vs. Fans

- A good window AC unit 

   * Runs on 1.2 kilowatts and costs 14 cents an hour to run.

- A three-ton central air unit (a common cooling system), 
   * Runs on about 3 kilowatts and costs about 36 cents an hour to run.

- A good ceiling fan
    * Draws only 30 watts to run, costing about 1 cent per three hours of use.
    * Uses less  than 1% of the energy of AC units.

Running the Cost Figures Over a Month

- A window AC unit 
$50.40 per month

- A central AC unit 
$129.60 per month

- Each ceiling fan 
$1.20 per month

Save over $128 per month by putting up a ceiling fan and weening off of AC.

Additional Benefits to Getting Rid of AC

- 25% of all electricity consumed at home in the U.S. is to power AC units.
   * Most of that electricity is coming from carbon-rich coal.
