We just bought our house a few months ago, so this is something I'm doing as well. I'm buying all energy-efficient appliances, and going 100% LED lights. I won't know my total energy costs until I fully move in, though, hopefully soon.

I became aware of this because last year I was hit with an electricity bill of $300 in a month because I ran a space heater every morning. After I did more investigation I realized I was paying about $40/month in electricity keeping my dual-CPU 8-core Xeon server running 24x7. The box alone ended up pushing me into the highest tier, so I was paying the highest rates for the last 5-6 days of the month, so it forced me to reevaluate my electricity use from the ground up.
