Energy-Efficient Models. An energy-efficient large freezer with more than 25 cubic feet will use about 956 kilowatt-hours per year, according to EnergyStar.gov. That equates to about $10 a month. When you reduce the size of your freezer, your costs go down. Standard freezer sizes run between 19 cubic feet and 22 cubic feet. Monthly costs for these units average about $67 per year or a little over $5 a month.
The numbers are convincing. For instance, if your fridge was made before 1980 and cools 19-21 cubic feet, you could save $1,005 over five years by upgrading. The calculator says your old clunker costs $246 a year to run, but an Energy Star qualified fridge costs just $45 a year to run.Thatâs $201 cheaper per year!f you are running a second freezer, you could unplug it and save $174 a year. (Thatâs for a 19-21 cubic foot freezer made before 1980.) Both calculations are using the average national price of $.11 per kilowatt hour.
