Saving Power in your Home Office
cweditor writes "Rob Mitchell shows how he measured energy use of all his home office equipment, and then targeted the energy pigs for replacement. With better equipment choices, he'd save $90/year. If you've got more than a couple of computers and printers at home (and if you're a Slashdot reader, you probably do), the savings would be a lot higher. Includes detailed formulas as well as a spreadsheet on monitor energy usage."
A typical slashdotter will likely save way more both nature and money in a year by just not buying one of the gadgets..
Ofcourse saving electricity is good, but often the total enviromental cost of disposing of the previous thing and the making of the new more energy efficient thing is way above any savings made by the new one..
How much money does it cost to save that much energy as well? I kind of scanned the article, but one thing I did notice was that $200 was spent on a new LCD monitor to replace the CRT. If we assume 100% of the energy savings came from that one purchase (which it didn't), it will take more than 2 years to recoup the money spent on that one purchase, and there was no indication that there was anything wrong with the older monitor other than that it used too much energy.
I would advocate buying newer more energy efficient equipment as your old equipment dies, but I would not advocate going out and replacing perfectly good equipment with more energy efficient (and more expensive) alternatives. It will not only cost you a lot of money, but will also mean more waste from throwing out perfectly good equipment that will likely end up in a landfill.
Craigs List? Or any other classifieds variants. You're making the presumption that both of those are going to waste when in both cases you'll be passing them on to someone else who would've gotten them from another source otherwise (which could be new or used)
