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...
If you want to take it a step further you can transition to solid state hard drives. They're more expensive than normal drives but remarkably faster and absolutely silent. They are more energy efficient but aren't as large as regular ones (gigabytes).
Please let me comment what I already have implemented. If you have further ideas, please share. It is interesting to see where this little brainstorming exercise leads to.

Again, thanks for your input sofar - keep it coming.
Things such as small wind turbines can be effective but depend greatly on the geography and size of your property. You could also look into solar power, but that can turn out to be a very expensive option!
It costs about fifty bucks for the local computer hardware genius to do it for me. I'm lucky to have found this guy's store. Possibly a good measure of someones work quality is by how busy their shop is. This guy consistently has clients at his counter all day long.
My wife's computer is a year old and I'm taking it down to the guy who built it for me so he can swap out the power supply. After experiencing the silence of the 750 Watt PC Power & Cooling PSU in my own computer, it's worth it to upgrade hers to a 450 watter that's energy efficient and quiet.
Any idea how much less a 19 inch LCD saves compared to a CRT?
However, bear in mind that your hardware will generally use very little power when you compare it with the energy you need to heat or cool your workspace. So look into your options for insulation, double glazing, and draught-proofing. If you swap your fridge, get an A+ rated one. I know I'm straying from your home office to the home in general, but these are the areas that will probably be costing you the most.
A couple of the practical things I do include:
Fitting one of those power cutoff smart sockets to shut down all the power bricks (powering injet printers, LCD monitors, etc.) when the PC is off.
Shut things down when not in use.
All the lights are CFLs (with a few specialist exceptions), along with an occupancy detectors in an area where we used to forget the light was left on.
I work on following: Not using the power in the first place, followed by energy saving measures such as those mentioned previously.

energy consumption meter and ... It's been a useful educational tool
1 watt == 1 joule of energy used/generated per second.
1 kilowatt (KW) == 1000 joules per second or 1 kilojoule (KJ) per second.
1 kilowatt-hour (KWH) = 3600 kilojoules.
By definition, power is the rate at which energy is converted from one form to another. The unit of power is the watt and the unit of energy is the joule. Capitals should only be used for the abbreviated forms (J, KJ, MJ, and W, KW, MW, etc.).
Hope that clears things up.
Have a good weekend!
