Some of you may remember that last year, when we first moved into the house, I was hit with a $500 gas/heating bill that sent me into convulsions. I hired an energy consulting firm to do an audit and they found some things (most notably that my contractor's team had kicked a duct in the attic loose and thus I was efficiently heating my attic for 2 months and not my house.) In addition, some other energy saving tips. I've sinced begun downloading my bill and tracking Therms consumed (since $/therms change) to see if we're making progress.
I'm proud to report that we are. The data (in an Excel pivot chart) is presented here.
