The electricity usage of a coffee machine depends on the coffee machine model.
Of course, larger coffee machines are going to use more electricity, unless they are very efficient.
On this page you will learn:

> How to reduce the electricity usage of a coffee machine
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.
Because we pay to our electricity provider 0,217 euro for every kWh we consume, to use this coffee machine model would cost us 8,2 euro per year.
38 kWh x 0,217 euro per kWh = 8,2 euro 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.
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.
For example, if your coffee machine has:
> A power rating of 1260 Watts
> It is in use 15 minutes per day and 320 days per year
> 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.

Still, if you want to know the exact electricity usage of your coffee machine, 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 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.
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.
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.
Or you can have a look to this electricity measurement units calculators to get a better understanding of:

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