Did you know that you can save energy by using a ceiling fan? They can save energy in both the summer and the winter. You simply need to change the direction of the fan each season. Most ceiling fans have a switch that allows you to reverse the direction of the fan.
In the winter, reverse the motor and operate the ceiling fan at low speed in the clockwise direction. This produces a gentle updraft, which forces warm air near the ceiling down into the occupied space.
In the summer, use the ceiling fan in the counter-clockwise direction. This blows the air down on to you and cools you off, much like a floor fan does.
