Many houses have electric coffee makers that are used regularly along the day.
So it is good to know how much electricity does a coffee maker use, the electricity cost and the ways to lower the electricity usage.
TABLE OF CONTENTS – QUICK NAVIGATION
Some coffee machines have energy efficiency labels that displays the yearly power consumption, and that information can be used to estimate the electricity cost.
For example, according to the energy label displayed on the picture above, this model uses 38 Kilowatt hours (kWh) per year.
In any case, the power/wattage of a coffee machine can be found by just searching on the internet for the specifications or even we can get the information from shops like Amazon.
When searching for a coffee machine model in Amazon, the product information section will most probably contain information about the coffee machine power consumption.
If you only know the voltage and current of your coffee maker, you can calculate the power consumption, in Watts, using the calculator below.
For more information about Power, Voltage and Current, scroll down to the ‘Electricity Measurement Units’ section.
Once you know the wattage of a coffee machine, the calculator below can be used to estimate the power consumption and the electricity cost of the coffee machine over a period of time.
You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.
> If your coffee machine has a power rating of 1260 Watts
> If it is in use 15 minutes per day and 320 days per year
> If you are paying 0,2 euro (or dollars, or pounds, or …) per every kWh you consume
You will be paying around 20 euro (or dollars, or pounds, or…) per year in electricity costs.
If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.
Alternatively, if don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
If you want to know the exact electricity usage of a coffee maker, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost.
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.
Have a look to this YouTube video for more information.
If you think that your coffee machine it is using too much electricity, here there are three simple ways to reduce the power consumption of a coffe machine:
1.- Turn it off, avoid standby power consumption
Some home appliances and devices keep using electricity even when they are not in use. This is because they stay in standby mode, which it is handy because you don’t need for the device or appliance to power on, but it consumes electricity.
If your coffee machine has an auto power off function, make sure that it is enabled.
If your coffee machine does not have an auto power off, juts switch it off manually if you are not planning to use it any time soon.
Have a look to this YouTube video for more information about what standby power is.
2.- Clean up the limescale accumulation
If you have hard water at home and you use that water to fill up your coffee machine, over time the limestone will accumulate.
Eventually, that limestone accumulation will damage your coffe machine making it less efficient and prone to use more eletricity.
If you would like to find out if you have hard water at home, have a look to this informative YouTube video.
3.- Buy an energy efficient model
If you have an old coffee machine, it may be worth to start considering to buy a newer and more efficient model.
But be careful, do not spend too much money on a mega efficient coffe machine because it may be not worth. In case of doubt, have a look to this post where we explain how to calculate the payback period.
It very much depends on the model.
If you own a coffee maker, it must have a specifications label describing the power usage in Watts.
If you plan to buy a coffee maker in a shop, you will be able to find the power usage in Watts by checking the specifications label or asking a shop assistance for support.
If you plan to but a coffee maker online, the website you are visiting should display the power usage in Watts on the description or technical specifications section.
It depends on what it is considered a lot of electricity.
Using the calculator from the ‘Electricity cost calculator’ section, you should be able to find the electricity usage and the electricity cost of a coffee maker.
Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would like to learn more about them, have a look to this YouTube video that we have prepared about this topic.
Or you can have a look to this electricity measurement units calculators to get a better understanding of:
> What is a Watt (W) and how to transform Watts into Kilowatts
> What is a Kilowatt (kW) and how to transform Kilowatts into Kilowatts hour
> What is a Kilowatt hour (kWh) and how to transform Kilowatts hours to other units
> What are Power (P), Voltage (V) and Current (I)
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.
If we could reduce the electricity usage of our coffee makers, even a very small amount, it would make a big impact on preserving our natural resources.
For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) on making coffee electricity usage, that would add to 32850 Kilowatt hour (kWh) saved per year.
9000 households x 0,01 kWh per day x 365 days per year
32,850 kWh saved 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) per kWh, we would collectively be saving nearly 6000 euro per year.
> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
In any case it is clear that small energy savings do really count when looking into the bigger picture.
If you are looking for saving electricity ideas at home, have a look to this YouTube video where we provide some useful tips to reduce the electricity usage and decrease the electricity bill.
Buying an energy effcient appliance or device is going to save electricity, water and decrease your energy and water bills, but at what prize?
