I recently moved into my house and I got my first full month's electric
bill and was floored. It was almost $150! I have never lived somewhere
with a bill over $80 for a single month. On top of that, this house does
not have some of the common big time electric drawing appliances. My hot
water heater, dryer and home heating are not electric. The only electric
appliances that run often are the fridge, the sump pump and a portable
dehumidifier in the basement

Anyway, I want to see if I can determine what the primary culprit is in
this very high meter reading. I am thinking it might be the
refrigerator. The fridge is an older, built-in Sub-Zero model which,
while nice seems to run a lot. Long story short, is there a device I
can purchase to put between the fridge's plug and the wall outlet that
will measure it's electric usage over a period of time, say a day? If
not, what is the best way to guage the usage of this appliance? I don't
have a backup fridge to use while I turn this one off for a month and
see what next month's bill looks like, so I'm looking for an
alternative.... Also, I looked up the model on the web, but did not find
any info on it related to electrical usage, so that is not an option...

Thanks in advance for any suggestions,

Rob

Use the utility meter. Switch everything but the fridge
off for one hour . Read the meter at start/end of period
to get the KWhr used by the fridg.

With the bill you have, the avg consumption must be
around 2 KWhr every hour.
