Many houses have electric coffee makers that are used regularly throughout the day.
So it is good to know how much electricity a coffee maker uses, the electricity cost, and how to lower the electricity usage.
TABLE OF CONTENTS – QUICK NAVIGATION
Some coffee machines have energy efficiency labels that display the yearly power consumption, and that information can be used to estimate the electricity cost.
For example, according to the energy label in 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 searching 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 probably contain information about the coffee machine’s 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 time.
You 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 euros (or dollars, or pounds, or …) per every kWh you consume
You will pay around 20 euros (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 you don’t have access to your contract or electricity bills, this website shows the electricity cost per country.
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
Suppose you want to know the exact electricity usage of a coffee maker. In that case, 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 will redirect you to the Amazon page where you can look at the specifications of the power meter we use for our measurements.
Our house appliances and devices like the washing machine, the dishwasher, the TV, or the printer are plugged into 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 time.
Have a look at this YouTube video for more information.
If you think that your coffee machine is using too much electricity, here there are three simple ways to reduce the power consumption of a coffee machine:
1.- Turn it off, avoid standby power consumption
Some home appliances and devices keep using electricity even when not used. This is because they stay in standby mode, which is handy because you don’t need the device or appliance to power on, but it consumes electricity.
If your coffee machine has an auto power-off function, ensure it is enabled.
If your coffee machine does not have auto power off, switch it off manually if you are not planning to use it soon.
Have a look at 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, the limestone will accumulate over time.
Eventually, that limestone accumulation will damage your coffee machine making it less efficient and prone to use more electricity.
If you want to find out if you have hard water at home, watch this informative YouTube video.
3.- Buy an energy-efficient model
If you have an old coffee machine, it may be worth considering buying a newer and more efficient model.
But be careful, do not spend too much money on a mega-efficient coffee machine because it may be not worth it. In case of doubt, look at 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 can find the power usage in Watts by checking the specifications label or asking shop assistance for support.
If you plan to buy a coffee maker online, the website you are visiting should display the power usage in Watts in the description or technical specifications section.
It depends on what is considered a lot of electricity.
Using the calculator from the ‘Electricity cost calculator’ section, you should be able to find a coffee maker’s electricity usage and cost.
Not everybody is familiar with terms like Watts, Kilowatts, or Kilowatt hours, so if you would like to learn more about them, look at this YouTube video we have prepared about this topic.
Or you can have a look at these electricity measurement units calculators to get a better understanding of:
> What is a Watt (W) and how do 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 do transform Kilowatts hours into 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 for your energy bills.
And it also benefits the environment because conserving electricity prevents unnecessary waste of natural resources.
At the individual level, it may not look worth trying to save a few watts here or there.
Still, every little count and if hundreds or thousands of us save a little every time, it will make an essential contribution towards conserving our natural resources.
If we could reduce the electricity usage of our coffee makers, even a very small amount, it would greatly impact preserving our natural resources.
For example, if 9000 households save as little as 10 Watts per day (0,01 kWh) on making coffee electricity usage, that would add to 32850 Kilowatt hours (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 euros (or dollars, or pounds, or any other currency) per kWh, we would collectively save nearly 6000 euros 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.
