Home Energy Audit Recap


Posted By on Jun 6, 2011

I just received our June CMP bill, and I am thrilled to announce with the changes we made over the course of May, we lowered our energy usage by 264 KWH compared to the same month last year!

Some of the changes we made:

  • We installed motion detector light switches in the kids bedrooms that automatically shut the light off after 5 minutes of inactivity.  (They think this is the coolest thing ever, and love “tricking” their lights)
  • I have been shut down the computer and switching the power strip off each night, as opposed to letting the compute go to sleep.
  • We also shut the power strip the tv, game system, dvd player, and cable box are plugged into off each night.
  • We have ordered new seals for the refrigerator & freezer.

Remaining on my To-Do list is:

  • Find out the energy draw of our water heater.
  • Compare the energy cost of running the EdenPure & pellet stove to the cost of heating with oil.

Energy Audit

I think I have found part of our energy hog!

To help supplement our pellet stove in the heating of our home, we have an EdenPure Electric Heater.  We purchased this heater after reading multiple reviews and even speaking with a couple very happy users.  EdenPure is known for being a safe electric heater.  The unit itself stays cool to the touch with the heat blowing directly from the front.  I even stacked the old newspapers on it, the kids tossed their book bags against the sides… never did anything get warm to the touch.  I was always careful to keep the front clear.  We ran the EdenPure basically all winter on the highest setting, with absolutely no problems with tripped breaker, hot cords, etc.  We did however, have a high electricity bill…

Energy Audit info:

29.04 KWH/24hrs

Comments: I did look into whether this energy usage is inline with what is expected for the unit, trying to rule out a malfunction in our unit.  Per the EdenPure website, these units will use no more that 1.5 KWH/hr.  So our unit is working within the expectations.

Since it was a bit chilly last night, we decided to run the pellet stove.  This was a great opportunity to check the electrical draw of our main heat source in the home.

  • We have a 3 year old 25-PDV Englander pellet stove.
  • We always have the fan is set on 9 (the highest level).
  • The auger speed (controls the amount of pellets dispersed) was typically set at 9 for most of the winter.
  • These settings would give the highest output of heat, and were the settings I used for the audit.

Energy Audit Info:

  • 3.06 KWH/24 hrs.

Comments: I feel this is a reasonable electricity draw for the main heat source of a home.  I would be interested to compare this figure to that of a heatilator on a wood stove or the blower on a forced hot air furnace.

My next step in our energy audit was the computer station power strip.

  • We have an HP all in one computer that is approximately 6 months old.  The computer goes on standby after 20 minutes of inactivity, but in rarely shut down.
  • We also have a Cannon all in one printer, which is typically left on.
  • We also have a modem and wireless router plugged into this power strip.
  • The last item plugged into the power strip is my Nook, which I charge overnight.

Energy audit information:

  • 0.64 KWH / 24 hours

Comments: Moving forward, I would like to shut down the computer before we leave for the day and before bed and turn the power strip off.  Why have the model, router & printer drawing electricity when no one is using the system?

First day of Audit


Posted By on May 2, 2011

I began my energy audit with the goal of finding a major energy hog, to the tune of 40+ KWH.  I chose to start with our refrigerator because it is the oldest appliance we own.

  • We have a Kenmore bottom freezer refrigerator
  • It is approximately 11 yrs old.

Energy Audit info:

  • 1.21 KWH / 24 hrs.

NOT, the energy hog.

90 – 1.21 = 88.79 KWH left to find.

 

Comments: Over the next month, I would like to install new seals for the doors.  Then re-test to see if that lowers the energy usage.
