Project: Power Bars

In combination with the energy meter I've been using, I was able to determine which devices in my house use phantom power even when the item is off. By connecting all of the items to a power bar and turning it off when not in use, you can turn that phantom power to zero. A good move.

The good news is that any cheap power bar will do the trick. The return on investment (ROI) is less than a year since you will save $10 - $15 or more per set. Spend less than that amount on your power bar, and your ROI is even shorter. You can buy a fancy power bar if you want to though. Some will even turn off peripheral devices when you power down the main machine.

This is one of those really simple things that you can do immediately with little or no investment (you probably have a few power bars already!). It's only a small drop, but it is enough to remove roughly 0.15 tonnes of CO2 from your footprint per year!
