Home Energy Efficiency and Major Appliances

Eventually, I want a net ZEH , a house that produces as much energy as it uses.

We are taking the small steps toward that end goal. Our initial goal is to reduce our energy consumption by 25%. For us that means reducing energy use to 38 kWh/day. Reliable sources, like my energy provider, declare our major household appliances huge contributors to our energy consumption.

Using our handy new Kill-A-Watt meter, we are now testing our major household appliances—the refrigerator, freezer, and hot water heater.

Today we have our refrigerator plugged into our Kill-A-Watt meter. The refrigerator is a GE 18.2 cubic foot, frost-free, refrigerator/freezer. It was here when we moved into this house ten years ago. I estimate it to be a 1996 model. I find no energy-star rating on it anywhere.

After twenty-four hours, I will check the reading and see how many kilowatt-hours my older GE refrigerator has used. Multiplying that number by 365 days in a year will give me an estimate of the refrigerator energy requirements over a year’s time. This information will help me decide if buying a new, energy efficient refrigerator would be a wise investment.

Perhaps leaving the refrigerator plugged into the Kill-A-Watt meter for a week or thirty days would give a truer estimate. Maybe I’ll do that another day.

But just now I am anxious to find out what I am paying for my stand-alone freezer which is 28 years old! That’s next!

I’ll let you know how this turns out.
