I like to know numbers when it comes to household operations. I track metrics on utilities because I like knowing how and why the bills are what they are. I’ve seen something on my utility statement that’s always kind of bothered me, but that I’d never bothered to investigate in detail.


You see, every 7-8 days I have a surge in the amount of electricity that I use. For a long time I wrote it off as the increased demand caused by my being home on the weekend. I took a closer look, though, and realized that the spikes in use don’t exactly correspond to the days when I just happen to be home all day. If they did, I should see three columns out of every seven standing out instead of just the periodic one day spike. I thought briefly that the spikes might be tracking the day I work from home – when I tend to have two or three computers fired up, the furnace running, and maybe a load or two of laundry snuck in to the mix. Those are all things that logically I understand consume electricity.

The problem is, that none of the usage spikes corresponded to anything like that. Some hit days when I was here. Some didn’t. Being slightly obsessive, I still wanted to know why.

I wish I could tell you I slipped off the toilet while standing on it to hang a picture and had a vision of the Flux Capacitor, but alas that isn’t the case. The culprit showed himself when I was laying out a couple of chicken breasts for a long cook. It turns out every spike in electrical draw showing on my most recent bill actually corresponds to a day when I had dinner cooking away in the crock pot.

I just assumed that the little fella sat there on the counter and cooked up a nice hot meal without drawing off as much power as I use to tend to every other electrical appliance and device operated in this house on any given day. I feel like this is something I should have known kind of intuitively since by definition the thing is sitting there drawing power for eight or more hours at a time, but honestly I’d never given it much thought.

If I were all green and earthy I might consider altering some of my crock pot recipes for oven-based cooking… but as in most things, there’s a prince to pay in terms of convenience. As it turns out it’s a price I’m happily willing to pay. I’m just glad that I now know I’m paying it… though it might just be time to go out and see if I can upgrade my 15 year old slow cooker to something newer and (maybe) more efficient.
