Our fridges are permanently connected to power, using electricity. 

Therefore, we need to be make sure that the electricity usage of our refrigerator it is reasonable and that we don’t not waste electricity unnecessarily.

How to calculate the electricity usage of a refrigerator

Nowadays the refrigerators are rather efficient and the electricity cost it is quite reasonable. 

Still, if you need to know how much does it cost you to run your fridge, you just need to make some basic calculations.

Refrigerator electricity cost

For example, according to this energy label, this fridge uses 389 kWh per year. 

Because we pay to our electricity provider 0,217 euro per every Kilowatt hour (kWh) we consume, this fridge would spend 84,4 euro every year on electricity costs.

84,4 kWh per year x 0,217 euro per kWh = 84 euro per year

Once you know your fridge’s model, it is quite simple to search on the internet how many kWh of electricity your fridge is using. 

Then, you can use the calculators below to estimate your fridge’s electricity cost.

Refrigerator electricity usage and electricity cost calculator

Note that this calculators do not account for factors that may increase or decrease your fridge electricity consumption. 

If your fridge it is old and the gaskets are damaged, the electricity consumption will increase.

If you are a Tetris master and you are able to pack the food into your fridge super efficiently, you may be able to reduce the electricity consumption.

This calculator will give you a good estimation on the electricity cost of your fridge based on its yearly power consumption.

 

For example, if your refrigerator:

> Has a yearly power consumption of 389 Kilowatts hour (kWh)

> You are paying 0,217 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 78 euro (or dollars, or pounds, or…) per year in electricity costs.

Alternativey, this other calculator will give you a good estimation on the electricity usage and the electricity cost of your fridge based on its daily power consumption.

 

For example, if your refrigerator:

> Has a daily power consumption of 250 Watts (W)

> You are paying 0,217 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 20 euro (or dollars, or pounds, or…) per year in electricity costs.

Still, if you want to know the exact electricity usage of your fridge, your best option is to use a plug in power meter to measure the electricity consumption. 

Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.

All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket. 

So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.

If you want to find out how you can use a plug in power meter to measure your electricity usage and electricity cost, have a look to this YouTube video.

What is a Watt, Kilowatt or Kilowatt hour

Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would learn more about them, have a look to this YouTube video that we have prepared about this topic.

How to reduce the electricity usage of a refrigerator

If you think that your fridge it is using too much electricity, here there are five simple ways to reduce the power consumption of a fridge:

1.- Keep the fridge full, but not too full

The refrigerator temperature can stay cooler for longer periods if the fridge it is full. Still, be careful, because a too crowded fridge will cut down the air flow and increase the risk of warm areas within your fridge.

2.- Do not put hot food in the fridge

Hot food will force your fridge to use more electricity and, also, the temporary temperature increase can be detrimental for the other food in your fridge.

3.- Check the door seals

A damaged gasket will let the cool air escape forcing your fridge to use more electricity to keep the internal temperature.

4.- Make sure that around your fridge there is enough space for a correct air flow

Around your fridge, specially behind where the condenser coils are, there should be enough space for air circulation. If your fridge it is placed too close to the wall, the condenser will not be able to operate efficiently and that will increase the electricity usage. Keep a distance of 30 cm between the fridge and the wall

5.- Keep your fridge in a cool area

If your fridge is placed near the cook, the oven or it is exposed to direct sunlight, the heat will force your fridge to use more electricity to keep the internal temperature.

Electricity conservation - Save and conserve energy

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

 

For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32,850 Kilowatt hour (kWh) per year. 

9000 households x 0,01 kWh per day x 365 days per year = 32,850 kWh per year

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) we would collectively be saving nearly 6000 euro per year.

> To produce 32850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.

Have a look to this page for more information about the amount of resources needed to produce electricity.
 

In any case it is clear that small energy savings do really count when looking into the bigger picture.
