A little over a month ago, Eric started looking into solar panels for the house. The process yielded some interesting information.
I’d always thought of ourselves as relatively energy aware people. I mean, we don’t run the air conditioning much, don’t leave lights on and are generally mindful of how much power we are using. I didn’t think of our bills as ludicrously high.
I was wrong. Though it’s not entirely all our fault, you’ll see.
As it turns out, the average kilowatt hour usage monthly (averaged over the year) for a house of our size is 632 kWh/month. We had been using an average of 1033 kWh/month. Jeez. And now I feel like I’ve revealed something like my weight. Anyway. We got an energy audit from Xcel Energy, during which I learned that our biggest electricity drains were our electric dryer and our electric water heater. Seeing as how we do at LEAST one load of laundry a day, our dryer gets a lot of usage. (As a side note, you always assume that you’ll do more laundry after you have kids because you’ll have their laundry to wash. What no one tells you is that they also manage to make your clothes filthy as well, so your overall laundry quintuples.) I’d always thought our water heater was gas. Of course, this explains why our gas usage is so much below the average–34 therms instead of an average 70 therms. In the summer, our only gas usage is our stove and the pilot light for the fireplace and our bill is only 7 therms/month.
So, a few changes.
Using this tutorial, I put up a couple clotheslines. (The lady may be a jailbird, but she’s got some good ideas.) We started the time-honored activity of hanging our clothes out to dry. Of course, since Colorado is well-known for late afternoon thundershowers, we also got to engage in the time-honored activity of scrambling to pull your clothes off the line before they get soaking wet again. And there was a minor emergency when a wasp got stuck in the corner of a fitted sheet and popped out of hiding while I was making the bed. A few times, we left the clothes on the line overnight and forgot it was sprinkler night. And yes, that’s practically our entire backyard, but the clothes never seemed to get in the way of kids playing. We managed to use the dryer only once.
We also made a concerted effort not to turn on the A/C at all. We’d have to open the windows every morning when it was cooler, then shut them and close all the blinds when the sun came up. It kept it fairly livable, though we did turn on the air conditioning one day when my mother-in-law was here. (See? Not my fault. I was forced to use more energy for the sake of family peace.) We also turned our water heater down a bit more and turned the fireplace pilot light off because, well, it was idiotic to keep it on in the summer anyway.
I eagerly awaited our September energy bill to see what the effect would be. I was expecting that the total would go down by around 100 kWh, but not hugely.
Our bill dropped by 300 kWh from July. Thirty percent. Our gas usage went from 7 therms to just 3. Our bill overall dropped by $46. Holy energy savings, Batman!
Obviously it’ll go up significantly in winter since we’ll have to use our dryer more and will have to run the heat. Of course, now that we don’t have little babies in the house anymore we can keep the place a little cooler and use more sweaters and blankets. Keep that in mind if you stop by this winter. We’ll never get below the average year-round simply because of the water heater and dryer, but I feel a lot better about cutting our usage at least in the summer months.
Now I just have to wait until the kids are tall enough to hang clothes themselves and then I’ll personally be able to expend less energy.

-Hang things up to dry indoors year round (use the shower curtain rod, clothes on hangars), and always run the spin cycle again before transferring clothes to dryer.
-Have learned that sheets and towels can be changed less frequently (= less laundry) without the sky falling….
-Blanket over mattress (under bottom sheet) warms up the winter bed nicely.
-Adding humidity makes lowered indoor temps more comfortable.
-Place foam gaskets behind switch plates on all outer wall outlets to reduce heat leakage.
-Use the disposer as little as possible to cut water waste.
-Instead of pouring down the drain, empty those half drunk water glasses into plant pots or yard (i.e. lower the waste water bill)
I like the blanket tip! Will definitely help this winter.
Yeah Energy Audits! You should also tell folks you can get a little bit of the money back as refund from the State @ rechargecolorado.gov.
But most important note, try to run your dryer in batches doing several loads sequentially. You save energy by not having it heat up several times from cold. The audit guy told me that.
Didn’t know that! Will check it out. Good tip on the dryer.
We made the mistake of installing an electric clothes dryer instead of putting more money up front to bring in a gas line (3rd floor!). Not only does the electric dryer practically burn the clothes, it is grossly ineffcient. So our solution is to run the clothes in the dryer for about 20 minutes on a low setting and then hang them to finish drying. Since the washer/dryer are in the girls’ bathroom, this means hanging clothes on a line strung across the tub, on a rack standing in the tub and on a rack in the hall. Not so great, but until they insist on taking showers every day, it works!
Our electric dryer seems to work pretty well (Whirlpool duet) but sucks up energy for sure. We’re going to have to move lines indoors for winter, too. I’m thinking about getting one of those multi-line retractable thingys–would that work for your house?
we were going to get one of these, but it didn’t really work space wise.
our friends have one and they are space saving wonders.
BTW, love the zinger at the end of the post. I almost feel like the whole post was a build up to that single joke!
