I spent some downtime on the train over the last couple of weeks entering numbers into Excel to see where our energy dollars have been going over the last number of years. I have paper statements up until 2010, which is where I stopped (in preparation for scanning and shredding), and I put in our charges for electricity, gas, and the average temperature as provided by BGE. Natural gas prices in the winter have been the biggest cost by far; electricity goes up as we run A/C units but overall it doesn’t see the same peaks and valleys as natural gas.

The downward trend in 2010 is interesting, and I’d like to see where that goes if I add data from 2011 onward, or if it’s an anomaly of some kind. Guess I’ve got to see if BGE will let me download bills from that far backwards or not…
