Energy Efficiency

The main goal of this house was to reduce overall operating expenses (mortgage payment, utilities, insurance).  Thus, I am keeping a spreadsheet of monthly utility costs.  Utilities do not bill at exact 30 day periods; thus, I calculate a "30 Day Equalized Amount" so that I can easily compare changes.  The first 30 days total gas and electric cost was $107.94.  The second 30 day period dropped to $91.35 due to warmer temperatures.  Thus, my two month average is $99.65.  The Energy Trust of Oregon estimates an annual monthly utility cost of $76.  I would like to beat that.  We'll see!  So far, I am very happy.  I was on an equalized payment plan at the Merlin house of $214/month.  So, I am definitely savings money!
