I’m a Watt Killa

In case you don’t know how amazing the library is, it is incredible!  And here is just one more reason why: you can borrow a Kill-A-Watt, for free, for a period of 7 days.

Amazing, right?  These things cost, like, tens of dollars, and here we are with the ability to use one for free.  Okay, that was slightly tongue-in-cheek, but really, they’re very informative little pieces of machinery, and really, how many of us are going to buy one?  But the chance to borrow one for free could save you, well, pennies on your electrical bill.

Here are the results of my meticulous testing:

– the fan we use for white noise during our toddler’s naps uses 23 watts, which works out to about 0.1 kWh per day for the length of time we typically use it in a day. 1000 watts for one hour = 1 kWh.  We are billed 5.6¢ per kwh, so this works out to be about half a cent per day.

– my desktop computer uses 80 watts when it’s on, and 3 watts when on standby.  Over a 24 hour period the computer and the monitor sucked back about 0.22 kWh, or 1.2 cents.

– a regular load of laundry added up to .13 kWh, and the heavy load was .15 kWh, adding up to .7 cents and .8 cents respectively

– our router uses 3-4 watts at a time, the modem 3 watts, the phone 3-4 watts, all of which are minimal costs as far as I can see

So, why isn’t our energy bill like 65 cents a month??  Unless my calculations are off, there is a big energy chomping monster somewhere in our house.

After some musing, I have concluded that it just might be our stove.  Unfortunately you can’t test the stove or any other appliance that uses one of those big-ass plugs.

But I did test the toaster, and it was up around 875 watts–and that’s just for those four little elements.  An oven must use a whole lot more, and I use the oven a whole lot.

So, did the Kill-a-Watt change my life?  No.  Unless my calculations are way off (and I’m certainly not ruling that out) the appliances I’ve targeted are costing us minimal amounts per month.  But I can tell you I’m a lot less eager to use our 1000 watt air conditioner this summer (though ask me about that again in August when I’m 8 months pregnant . . .).

Now I just have to figure out how to determine my oven’s energy use.  And if that’s not the energy demon, find the actual demon that’s obviously sucking on our electrical outlets when we’re not looking.
