Conclusion: BUSTED.
This eco-myth was sent in by a SustainLane community member:
"Shutting down a computer causes more harm to the hard drive and other components than the worth of the energy saved. This myth keeps so many of my friends and co-workers machines on 24/7 (even over 4-day holiday weekends).”
Truth: Years ago, the accepted belief was that frequent starts and stops to your hard drive made it more prone to crashing. But with improved technology, it’s perfectly safe to start and stop your hard drive. Experts now say that the biggest threat to your hard drive is actually heat, which will cause your hard drive to age prematurely. Keep your computer as cool as possible as often as possible: shut it down when it’s not being used.
Powering down your computer at night will extend the life of your hard drive and conserve electricity. To save even more power, switch your computer monitor off when you leave your desk for long periods of time, like for lunch breaks or meetings.
Have a friend who swears turning off the light when you leave a room actually wastes energy? Does your uncle tell you Hummers are more eco-friendly than hybrids? Whatever the eco myth, we'll help you get to the bottom of it. Submit your myth to SustainLane Greenbusters.
