When I first used to think of conserving CO2, I started to think about electric and low mpg vehicles. My household appliance use remained off the radar until we started discussing LEED vs. Energy Star in our Habitat Development meetings. The argument between LEED and Energy Star not withstanding, the point is, appliances with a better efficiency rating will save you money when you’re using them.
The rest of this original post has been moved to a new blogsite I'm using to discuss energy, processes, and special projects. See more about my appliance usage matrix there: http://leandisciplinedsystems.blogspot.com/
