Laundry Challenge 1 – How Much Energy Are We Using?

kill a watt

This is what the kill a watt looks like

I was interested in learning how much energy our washer and dryer actually used so I plugged them into the Kill a Watt.

I’m going to date myself here but girls weren’t allowed to take electrical or shop class when I was in junior high so I’m not exactly sure what all the numbers mean on the Kill a Watt measuring instrument, but it seems that the washer used .10 killowats/hr for one load of laundry, cold water delicate, and .16 hot water heavy load. And it appears that the dryer used .26 killowats regardless of whether it was on air, tumble dry or high heat.

(If someone out there wants to explain watts and hz to me, please do. If I’m going to become energy smart, I guess I need to know this.)

So if I’m understanding this right, the dryer is 2x to 2.5x worse in terms of energy use. I’m going to say that’s pretty convenient because it seems like it would be a heck of a lot easier to find alternatives for drying. In fact, I’ll post some soon.

    I have been interested in getting one of those kill a watts. I have everything in my room aside from my clock and phone plugged into a strip that I turn off when not in use. I would love to see the difference between just turning them off and turning the strip off, and how that translate into dollars.
