In terms of equipment, there isn't a whole lot you can do (that will make a real difference). However, good habits can have a noticeable effect (such as not leaving computers running screen savers for hours on end).

If you have halogen lights, consider replacing some with LEDs. If you have filament lights, consider replacing all with energy savers. If you have air-conditioning or heating use it less.

Returning to equipment, a 19-inch monitor will normally use less energy than a similar 22-inch one. You can also get desktops built around mobile (low power) CPUs. The last time I looked, mobile AMD Semprons and Mobile Intel Celerons weren't bad, however the saving is likely to be less than 50 watts (but a quiet PC is nice).

Since this is a home/office, it's hard to see how you might justify green claims unless your whole house is green, and you drive a small car, and recycle etc...
