Mac vs PC power consumption

I bought a new toy. A P3 International P4460 Kill A Watt EZ Electricity Usage Monitor. I want to know how much power various devices use. I am pretty good about turning off power strips and devices when we don't use them. There are some items that stay plugged in all day.

The device arrived today. The first two things I tested were my laptop versus Kelli's current laptop. My computer (Macbook Pro) has a faster dual core processor, faster hard drive and larger LCD screen. One would think mine would be more power hungry.

Below is a photo of what it cost my computer for one year.....$27.19


Now what it cost to run Kelli's laptop for one year.....$56.41


The difference is almost $30!

Both computers were tested in "high power" mode. Crazy.

The device is very user friendly. I am able to set the actual rate per kilowatt that we pay. More test to come.

  1. If I hand the fundage I would buy a mac - I've wanted one for a while but your glowing commentary on them just makes me want one all the more!!
    When I finally (if I finally) get around to getting one, I'll be running to you for assistance with my purchase!!
