Saving Energy With Your Computer

Posted by on Jul 14, 2010 | 3 Comments

FlavioGomes asked the Lockergnome community how we can save money and energy with our computers. He has to leave his machines on all day, and he claims that it makes a big difference in his electricity bill each month. He’s hoping to find a way to cut that down, without having to turn off his machines. Any advice or tips you have will certainly be appreciated!

Generally speaking, the best way to save money is to not use your computer. If you are using it, you may not want to use it to its full potential. Notebooks have certain features which can keep the processor cool and clean, unless it needs to do something processor-intensive (such as video editing). The things you’re doing can save you money.

If you’re going to be away from your machine, you might think about turning off the screen. That can save you money without having to turn off the computer. You could also put the machine into hibernation or even shutting it down entirely. I know it’s a pain to have to wake the computer back up or power it up. However, you have to weigh the pros and cons. Do you want to spend a moment or two powering back up… or do you want to pay more each month on your electricity bill?

Turn off peripherals when you aren’t using them… especially laser printers. Those suckers eat up a lot of juice when they’re just sitting there.

If you have any other money-saving tips, please pass them along to the community — either here on the blog, or in the original thread on Lockergnome.

    if your computer perform tasks which shall run 24/7 (say download stuff, serve network storage and printers and whatnot) you should consider building a low-power pc for that… most of those tasks don’t need much computing power so you would be fine with onboard graphics instead of a discrete card and a low-power dualcode processor with activated energy saving features… even if there are demanding tasks (say video conversion) such a pc should suffice for it runs 24/7… however you should use energy efficient components across the board (mb, cpu, ram, hdds) and an efficient power supply (80%+) with fitting output (supposely max 300w)…

    also if you need to use different operating systems for your tasks make use of virtualization software… this way you can run those os on the same host…

    at least thats the way i do it… my home server pulls some 70 watts or something but it hosts a linux firewall (with all the bells and whistles) and a linux server in virtual machines and network storage as well as printing plus terminal services on the host os which is windows… that said i can easily expand functionality and even reduce the energy footprint further since my hardware setup includes an old pcie graphics card (g45 boards are more expensive than p45 ;) )

    Nice tips! Few years ago I was on a business trip and always kept wondering why my notebook’s battery isn’t lasting more than 2 hours…

    I think a good idea for home PC’s is to plug the PC and peripherals (printer, speakers) into a Power Strip or Surge Protector. Then turn the strip off at night which will shut everything down and stop any power drain ($). Even “off” items use some electricity when plugged in to a normal elec outlet, a power strip will stop that when turned off.
