You'd be surprised by just how much power people could save by turning off the lights! On average, one light bulb uses sixty watts of energy per hour. Let's say you turn off a certain light for one hour daily. After a year, you'll end up saving over 22,000 watts of energy. Electricity is saved if lights are turned off every time you leave a room for more than a few minute, but the surge of power required to restart the light when it is switched back on may cancel any saving if the light has been turned off for only a few seconds.

Turn on one of the switches and leave it on for a few minutes. Then turn it off and turn on another switch. Proceed upstairs and touch the light bulb. The bulb that is warm corresponds to the switch you turned on first, and the bulb that is off and not warm corresponds to the switch you turned on second.
