How Much Energy Does a Mini Fridge Use? Reasons for High Energy Use. On average, a standard model mini fridge uses roughly 230 kilowatt-hours per year, as much as many Energy Star rated full-sized refrigerators.The amount of energy a mini fridge consumes is due in large part to poor insulation and lack of cooling features.ith the number of variables that factor into appliance energy consumption, it is difficult to predict how much energy a mini fridge may use. However, there are ways to estimate energy use and cost based on the wattage ratings of appliances.

Refrigerators All the time your refrigerator is humming away, liquids are turning into gases, water is turning into ice, and your food is staying deliciously fresh. Let's take a closer look at how a refrigerator works! Photo: A typical domestic refrigerator or fridge keeps food at a temperature roughly 0–5°C (32–41°F). Freezers work in a similar way, but cool down to a much lower temperature, typically −18 to −23°C (0 to −10°F).

Watts consumed by refrigerator About $21. If you’re trying to compare the watts consumed by a refrigerator you already own, to that of a refrigerator you plan to buy, the best approach is to buy a Kill A Watt meter or other electricity usage monitor and use it to measure your current refrigerator energy consumption.or example, I plugged my Kill A Watt meter into my Maytag 18.5 refrigerator and left it in for about 3 days. After 74 hours and 53 minutes the Kill A Watt meter registered 3.96 kwh. Here’s how I determined the watts consumed by my refrigerator per year:

The Wattage Requirements of Average Refrigerators Average Wattage. An average 21-cubic-foot side-by-side refrigerator-freezer demands about 780 watts when in operation. Once you know the wattage demanded by your refrigerator, you can figure out how much the refrigerator costs to run.ecause refrigerators cycle on and off all day and night, the U.S. Department of Energy’s rule of thumb is to assume eight hours of operating time per day. If your refrigerator demands 780 watts, multiply 780 by eight hours to get 6,240 watts per day.

What Is the Wattage of a Refrigerator? Multiply the refrigerator's kilowatt usage by 225 hours — what the Otter Tail Power Company reports as mid-range usage — to estimate how many kilowatt-hours of electricity it uses per month. A refrigerator that uses 0.7475 kilowatts may use 168.2 kilowatt-hours per month, which costs just over $20 per month as of 2013.

- typical refrigerator 425 kWh / year = 1,450,000 BTU According to this chart, (http://michaelbluejay.com/electricity/cooling.html) the fridge competes with the A/C at a rate of 1 to 6. So if you run your fridge indoors in summer for 24 hours you add 4 more hours of A/C to even it out. So, I'd use that porch.

How to Repair Your Refrigerator Repair: Let's say your refrigerator uses $20 of energy per month, which is $240 a year, Spencer says. A new Energy Star refrigerator will cost $10 a month, or $120 a year, to run. A new Energy Star model costing $500 will pay for itself in just over four years in energy savings. Likewise, an Energy Star fridge priced at $1,000 will take just over eight years to pay off in energy savings.
