National Geographic has built a pretty interesting online resource for looking at your personal energy consumption compared to your friends and neighbors. The tools are all part of The Great Energy Challenge designed to help you understand your current energy situation.

The tools range from easy-to-digest mini-calculators to the more comprehensive personal energy meter. I found all of the tools educational, but learned the most from the mini-calculators. Personal note: I need to take care of the energy vampires that lurk in my house!
