Use Less paper - Turn Off Your Printer!
There is very little that I look at on my computer that actually needs to be printed. In fact, my printer isn't even connected to my PC anymore, much less turned on. There is a printer in the house, connected to the PC my husband uses for his business, so if I absolutely have to print something, I can, but the inconveneince factor means that most of the time I simply save a copy of whatever it is where I can access it late if needed and forgo the option of printing it out. Screen capture programs and the ability to print to a file usually eliminates any need for printing. Most of the time, having a digital copy of something rather than a printed copy also makes it easier to move data from one place to another by cutting and pasting. This same idea can also be applied to other areas - if you make it inconvenient to yourself to do something, you will tend to do it less often! How can you apply this idea to your own home?
