We hope these tables charts will help you to better estimate how big and powerful generator you will need as a backup source of power.
Refrigerator energy consumption per day.
Multiply the hours used on the average day by the wattage listed below.
Before you think okay great now i know how much power my fridge uses sorry to say but it.
Click calculate to find the energy consumption of a refrigerator using 180 watts for 24 hours a day 0 10 per kwh.
Energy efficient refrigerators come with a government approved rating called bee star rating which represents the refrigerator s efficiency towards electricity consumption.
Domestic fridge power consumption is typically between 100 and 250 watts.
While energy star fridges use 20 less energy than standard models cee tier 3 ct3 fridges use 30 less.
The kettle is used several times per day for about 1 total hour.
For example if the annual kwh rating is 875 kwh divided by 365 days will give you about 2 4 kwh per day which means the average wattage accounting for all factors is about 100 watts.
This translates into a running cost of about 150 per year per fridge.
Following the steps above find the annual cost to operate an electric kettle.
E kwh day p w t h day 1000 w kw.
Actual savings may vary based on use upkeep and other factors.
A modern era energy star rated fridge by comparison might only use 350 kwh annually.
The energy e in kilowatt hours kwh per day is equal to the power p in watts w times number of usage hours per day t divided by 1000 watts per kilowatt.
A 300 watt item used for 5 minutes per day will only consume 25 watt hours per day.
If you pay 10 for electricity per kwh that means the aging refrigerator is costing you about 55 per day 16 67 per month and 200 per year.
Annual energy consumption utility rate per kwh annual cost to run appliance.
How to identify an energy efficient refrigerator.
The wattage is on the label and is listed at 1500 w.
Over a full day a fridge is likely to use between 1 to 2 kilowatt hours kwh.
Remember that some items such as garage door openers are used only for a fraction of an hour or minute per day.
The average wattage of the refrigerator 2 3 kwh 2300 watts per day.
Source pdf that s great for those who want to be as efficient as possible but at 15 kwh that extra 10 amounts to only 9 year savings over an energy star fridge.
