Save $100 By Simply Turning Off Your Computer

Running your computer is pretty darn cheap when viewed at an hourly rate – approximately $0.02 an hour. This figure was obtained with the following assumptions: The typical desktop computer uses around 200 watts of energy per hour (with a 50% / 50% split of energy consumed between the computer and the display screen). We pay about $0.10 per kilowatt hour for electricity where I live (this varies across the US, so you can put in your actual rate here). From there you simply divide the watts used by 1000 (since electricity is charged at a rate in kilowatts – 1000 watts) multiplied by the rate charged: 200 divided by 1000 = 0.2 x $0.10 = $0.02.

With the cost of using a computer so cheap, many people believe that it isn’t worth the time to bother turning it off. When multiplied over time, however, it can add up. That $0.02 an hour comes to $0.48 a day, $3.36 a week, $13.44 a month and $175.20 a year if you leave your computer on 24 hours a day, 7 days a week.

That means if you turn off the computer for half the day while asleep, you have saved $87.50. Add in a few extra hours it will likely stay off on the weekends, and you have reached $100 a year in savings by simply turning off your computer. If you have a small business with 10 computers, making sure they get turned off at night means an extra $1000 to your bottom line (and if you work for a business that rewards employees that submit money saving ideas that get implemented, you could even earn a bit of money by suggesting this).
