Somehow, I didn't get around to posting this for reasons of sheer laziness and nothing else - It took an entry on Treehugger to remind me that there is a very simple way people can figure out how much energy they use at home, and now, at work as well and how to reduce its consumption: http://www.treehugger.com/files/2008/10/energy-star-at-work.php
Consider that the original Energy Star @ Home and the new Energy Star @ Work programs were initiated by the Federal Government and you know that not all government departments are a dollar black hole. These guys need to be saluted for their good work!
Edit: Another government initiative from Switzerland and brought by Treehugger again: http://www.treehugger.com/files/2008/10/using-lca-to-promote-video-conferencing.php This one suggests something that I used very actively when I worked in the past - video conferencing. Saving on energy use in transportation is a big part of showing Fossil Fuel the Fist. Nice, very nice!
