So I just recently got into watching Mythbusters. It's pretty darn entertaining, I have to admit. Although...some of the myths come as a surprise to me. I just saw an episode (although I think it was an old one) where they were looking into the myth which said it's more energy efficient to leave your lights on. The claim was that it took so much energy to turn the light on or off that a constant "turned on light" ended up being more efficient. Well, of course, that was not true at all for any light they tested. Definitely not for LEDs, not for CFLs, and not even for traditional incandescents. They tested a few others as well. The evidence overwhelmingly showed that you should turn the lights off when you don't need them.
First...has anyone ever heard this myth before? It seems so totally counterintuitive to me...however...I *have* heard the story that it takes more energy to turn your computer on and off than it does to leave it on.
