- 9,500 hours of monitoring
- 1,440 KWH of power consumed
- $262 expended
- Average of 152 watts/hour
So why do I bring this up? Pretty much to make the point that PCs need to be turned off when not in use -- especially high-end desktops, which consume huge amounts of power. It also makes me ponder the viability of a desktops in the first place.
My new MacBook Pro consumes less than 85 watts of power when it is on, and has pretty impressive graphic performance (good enough for all but the leading-edge games). If I were to simply dock that to a large monitor I would have a computing experience that was almost identical at a fraction of the power (probably 1/5). So that would be $190 a year in my pocket in terms of power savings.
Now the power consumption I am reporting is for the Monitor and Desktop itself. I did NOT measure the power consumed by the UPS, which as I have mentioned before, depending on model, can be quite inefficient -- especially on stand-by. Another advantage of a laptop is that a UPS is no longer required (the battery in the laptop performs that roll). So the laptop avoids the first cost of purchase of a UPS and saves just about another $50 a year.
