This flip your fridge calculator is designed to provide an estimate of the savings associated with replacing or removing an old refrigerator or freezer with a new energy star certified model.
While energy star fridges use 20 less energy than standard models cee tier 3 ct3 fridges use 30 less.
Before you think okay great now i know how much power my fridge uses sorry to say but it.
A modern era energy star rated fridge by comparison might only use 350 kwh annually.
This translates into a running cost of about 150 per year per fridge.
Annual energy consumption utility rate per kwh annual cost to run appliance.
Domestic fridge power consumption is typically between 100 and 250 watts.
Multiply the hours used on the average day by the wattage listed below.
The average wattage of the refrigerator 2 3 kwh 2300 watts per day.
Click calculate to find the energy consumption of a refrigerator using 180 watts for 24 hours a day 0 10 per kwh.
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.
Energy efficient refrigerators come with a government approved rating called bee star rating which represents the refrigerator s efficiency towards electricity consumption.
The kettle is used several times per day for about 1 total hour.
A 300 watt item used for 5 minutes per day will only consume 25 watt hours per day.
Actual savings may vary based on use upkeep and other factors.
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.
How to identify an energy efficient refrigerator.

That is why we have decided to create this list of rough estimates of wattage consumption of most common household appliances that people want to keep running at all costs.
Following the steps above find the annual cost to operate an electric kettle.
The wattage is on the label and is listed at 1500 w.
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.
