Skipping A/C Saves Money

In a 2008 Time Magazine article, Lee Shipper of the University of California, Berkley estimated the cost of air conditioning usage to be 20 cents per kilowatt hour. He also estimated a savings of four percent for every degree you push up the thermostat.

You can lower your costs by using fans and ceiling fans, opening windows and creating cross-currents to cool your home. Also, use heat-producing appliances such as dryers during cooler times of the day and close your shades during the hottest part of the day.
