Geek Tip: The Cost Of Leaving Your Computer On

Ever guesstimate how much it costs to leave your computer on 24/7?

According to coding, it cost the average household 14.28 cents per kilowatt-hour when their computer is left on. Keep in mind that this figure has been determined by the power rate in that given area (this example being in California) as well as what the power draw in watts is (by using a special device to measure this). At 14.28 cents per kilowatt-hour, this would mean that it will cost a total of $200 per year or $16.68 per month. This can be quite the money grabber and not to mention energy sucker!

I have to use my computer all day for school. But I do turn it off at night.

Ok, I just read the article and he's talking about a server here. Servers usually have several hard drives going and are in near constant use (not just powered up but actually working hard). The average home computer will be more like his media PC (~$7/mo for a total of $81/year in the article). While that does suck if you aren't using it a lot, it's still not the reported $17/mo. I would say that if you are leaving your computer on unplug (often just turning something off isn't good enough) anything that you aren't using often, invest in an LCD monitor instead of CRT (I saved dollars a month that way), and put anything you can on standby when not in use.

It's just as hard on your computer to leave it on all the time if you aren't using it. Furthermore, letting your computer sit on a network without being near it to do updates is asking for problems with security. I've left my computer on since we created it about 4 years ago and everything goes out on that darn thing (power supply, hard drives, fans, etc.) Especially a fan spinning constantly at that speed will eventually crap out. The not turning it off myth is similar to the letting your car run during errands/sitting at the drive through myth, it's only energy efficient and good for the parts if the time between use is extremely minimal. As for this information, computer power consumption varies dramatically depending on if you have a laptop or desktop, what kind of power supply you have, etc. I have a 350W power supply running 24/7 in Colorado. My entire electricity bill for a month varies between $12-$20 and that includes a stove, fridge, computer/computer components, 5 light bulbs for most of the evening, tv/tv components, and alarm clock at minimum. Energy costs must be ridiculous where this study was conducted.

I have heard it is better for your computer to leave it on 24/7. The logic has something to do with most hardware malfunctions happening when you power up or down. Perhaps someone can shed some light on this?

You should also use a surge protector for all your plugs and turn that off as well. All direclty-plugged-into-the-wall appliances, even when off, drain just the smallest bit of energy (and that adds up).

I've always wondered and worried about this. My comp is on for about 16 hours a day and I know it's a major drain.

This is an eye-opener. Better for the wallet and probably even the environment to just turn it off when you aren't using it.
