The electricity usage of a desktop computer it is rather difficult to calculate because many factors do affect the electricity consumption.
For example, a desktop computer that is used for gaming may have a very power hungry graphic card or a desktop computer used for cryptocurrency mining may have the CPU working non stop at 100% capacity.
In those cases, the electricity usage it is going to much higher than a PC that it is only used for browsing the internet.
In average, a computer can consume between 60 to 300 Watts, but this is only a very rough estimation.
If you know the power consumption of your computer, below we have provided a calculator that can be used to estimate the electricity cost over time.
If you don’t know the power consumption of you computer, below we are providing the means to find out the power consumption by using a plug in power meter.
The calculator below can be used to estimate the energy consumption and the electricity cost of a desktop computer.
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 desktop computer has:
You will be paying around 200 euro (or dollars, or pounds, or…) per year in electricity costs.
Still, if you want to know the exact electricity usage of your desktop computer, you need to use a plug-in power meter.
For more details, have a look to this post that we have created to show you how to use a plug in power meter to measure your appliances and devices power consumption.
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 video that we have prepared for you.
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 32850 Kilowatt hour (kWh) per year.
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
In any case it is clear that small energy savings do really count when looking into the bigger picture.
