Temperature dips, bill goes up: What can I do?
Tracking your electricity use will show how well you're coping with the cold
The heat is on.
That's become obvious from my November BC Hydro bill, which will cost me an estimated $61 compared to the $32 I paid a month earlier. And the picture is particularly dramatic when I log in to bchydro.com and use MyHydro to plot my energy use against average outside temperature. I've included that graph at the top of this story, and it underlines the cold truth of winter energy bills in Canada.
I was still surprised, however, when I chose a comparison of this year's electricity use vs. the same period last year. This is what it showed.
Why did we use more electricity last month than a year ago?
I suspect that we may have cranked the heat up a little bit higher than usual when the colder days hit, in part because a couple of us were sick with a cold and really feeling the effect of the late-fall chill. There were even a couple days where we stayed home from work.
But why was our usage so much higher than a year ago?
Again, MyHydro had the answer. Below you'll see that temperatures during this period last year were significantly warmer than this year. Twelve days were above 10 C, and no days dipped below 5 C. But over the past month this year, we had just two days above 10 C, and five days with temperatures between .3 C and 4.2 C. And that’s when our usage really spiked, which you can see in the graph at the top of this story.
With the coldest days yet to come, how can we keep heating costs down?
We're going to pull out the sweaters and slippers and get more careful about turning down the heat when we're away. If we go away skiing for a few days and turn our thermostats down to 16 C before we head out the door, we're going to save a lot.
As one of my fellow BC Hydro writers discovered last winter, just maintaining a home's minimal warmth during the coldest days can be costly. So consider resetting your thermostats, manually or through a programmed schedule, regularly.
Here are some of the other things we're going to change or consider changing as the days get colder:
- Checking the draft proofing on our two entry doors. Is the draft proofing I did prior to last winter still doing the job?
- Applying plastic film to the inside of several windows. We may consider doing this if the temperatures really dip.
- Monitoring how much laundry we're doing. Our son tends to toss everything into the laundry hamper, even if it's not dirty and sometimes when he's just trying stuff on. If we limit the number of loads we do – and always wash full loads – we'll cut our costs.
- Adding the area rug to the living room. Wood and tile floors can make us cold, and convince us to crank up the heat. Grabbing the wool area rug for the living room out of storage should make a difference.
