Sleeping does not always mean saving.
I read a compelling tweet this morning from @Dan_at_Avista that made me think. Fifty Six Dollars a year in energy costs annually for a home computer that isn’t in sleep mode, heck – even in sleep mode that’s $16 per year in energy costs.
I quickly started doing the math… I’ve got at least two to three computers running at any given time; a file server, a laptop and another that I use to test new software and tools on. Admittedly – I’ve not been the best at turning these off when I’m done, because afterall, it’s just a computer how much harm could it cause. I’ll tell you what – it’s a tank of gas, per computer, PER YEAR. That number doesn’t even include the monitor which is $9.20 for an LCD or $37.00 for CRT (not using sleep mode).
Other culprits include: Copiers, scanners and printers. These devices also use power while in sleep mode. I did the math – my home office costs me about $150.00 per year in unseen energy costs (works out to be a little over one month’s totall bill). Looks like my to-do list for the weekend just got bigger.
