Saturday afternoon I did a yearly sweep of my accounts and downloaded all statements into categorized folders, archiving 2020 into one place. Among the records, I’ve got a record of all of our gas and electric bills from the day we bought the house until now, save a period from March 2010 to October 2013, because BG&E doesn’t save stuff that far back. In 2014 past I plotted our energy usage against the average temperature to see what the pattern was.

Looking back at that graph I realize now that I was plotting the wrong thing: I was interested in cost, which made sense back then, but because pricing fluctuates over time it wouldn’t tell the story I’m more interested in now—about any improvements made in insulation. This would be reflected in the total therms or KWh used, which BG&E helpfully includes on their statements (as well as the average monthly temperature). I dug up some further statements and spent a couple of hours plugging data into the old spreadsheet.

What I found was interesting. Apparently our gas usage has trended downwards by about 50 therms over 17 years, which means that some of the improvements I’ve made in this drafty sieve have made a difference. The scary revelation is that our energy usage has trended upwards dramatically by about 250KWh over that same time period—no doubt the spike in daily usage during 2020 did not help that average. But it tracks; there are three people in the house using appliances and devices and air conditioners instead of two, and we’ve added multiple rooms since 2003.

The big takeaway is that we’re still spending more in the winter to heat the house than we do in the summer to cool it, so my continual quest to insulate and weatherproof will continue. I think nine new windows for the upstairs rooms would help with the drafts as well as some other upgrades—I’m looking at you, front and back doors—and eventually a central air unit that would be four times as efficient as four old window units sucking dollars out of the house.

While we’re on the subject of drafty houses, Finley has been working from her fort while she’s in class. The high is around 48˚ and there’s no insulation out there, so I ran an extension cord from the garage and put my shop heater on a plank of wood to try to combat the cold. She used some Christmas money to buy a small laptop stand and a whiteboard at Target, and over the weekend went out to set things up. Back in the summer the neighbors gave us an old carpet which fit pretty well on the floor, so she’s not sitting on a bare wooden plank, but that’s it for amenities. I dusted off our old Airport base station, reset it for bridge mode, and tucked it up above the workbench in the basement. The new router sits in the living room roughly where the old one did, but if I draw a straight line from that to the fort there are two surfaces covered in aluminum siding in the way, which means the signal is shit out there. So the Airport should keep her Zoom game strong.

I’m a little wary of letting her work out there by herself, but we told her she could do it as long as her grades stayed up and her work got done. So we’ll see how things go.
