A common misconception about saving energy is that leaving
lights, computers, and other electric appliances turned on when you are not
going to be away for very long is a good idea. Switching them on and off all
the time wears them out more quickly, and also produces sudden power spikes
that negate any supposed energy savings.
If there were ever any legitimacy to this idea, there isn’t
anymore. Switching sophisticated modern appliances and electrical devices on
and off frequently will not reduce their life span, and any power surges that
might occur are likely to be minuscule. The bottom line is that if you aren’t
using an electrical device, it should be turned off; period, case closed.
