MYTH #1: Leaving a light on uses less energy than turning it off, then on again

Some people believe that if they leave the light on when they exit a room for a few minutes, it's better than turning the light off and then on again when they return. This is simply not true – it's always better to turn the light off.

There is no significant additional power draw when turning on a light bulb (other than the calories you use by flipping the switch). So, turn off the lights each time you leave a room, even if for just a couple of minutes.
