The spreadsheet shows the number of hours and the average (winter and summer) cost per Kilowatt for my utility. The Kill-a-Watt has a timer, and it accumulates the energy used. So calculating the KW per hour is simple.
- The new fridge is smaller than the old one
- The new one does not have an ice maker
- There is no light in the freezer
I know now that I should have replaced my fridge sooner since at $50+ per year saving, a $1500 refridgerator will pay for itself in 30 years, assuming it lasts that long.
