Same brand, different models
Zephyr makes 39 ENERGY STAR certified refrigerators; this one ranks 9 of 39 for running cost, between the brand's cheapest, the PRRFD24C2AP at $13/yr, and its priciest, the PRRFD24C2AS-OD at $62/yr.
What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the Zephyr PRW24C02CG that long and it costs about $381 in electricity, on top of whatever it cost to buy.
Weighing a replacement
The Zephyr PRW24C02CG is already efficient for its category at $29/year. If you're shopping and comparing options, this is roughly what a well-chosen new refrigerator costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
At $29/year just to run, a refrigerator is worth protecting against an unplanned repair bill on top of that.
