PC monitor power consumption and electricity cost

Nowadays, computer monitors are rather efficient, so the electricity usage of a computer monitor is quite low.

Still, in case of doubt, it is advisable to check the electricity usage of our computer monitors and find out the electricity cost of using them over time.

How much power does a PC monitor use

All the computer monitors should have a label describing, at the very least, the energy consumption. Some monitors will also be labeled with information about the standby power consumption.

Considering purchasing a new PC monitor, look at the specifications. The computer monitor specifications must clearly describe the power consumption.

For example, according to the energy label from our computer monitor, it uses 0,21 Watts (W) per hour while on standby.

0,21 / 1000 = 0,00021 kWh

How to calculate power from voltage and current

If you only know the voltage and current of your air computer monitor, you can calculate the power consumption in Watts using the calculator below.

But, no need to do the calculations by hand.

The calculator below can estimate computer monitors’ energy consumption and cost over time. And it can also be used to calculate the standby energy consumption and cost.

You 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 computer monitor has a power rating of 25 Watts

> f it is in use 8 hours 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 12 euros (or dollars, pounds, or…) per year in electricity costs.

How much does electricity cost

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.

Home appliances and devices electricity calculators

Here are a few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:

PC monitor electricity usage monitor

If you want to know the exact electricity usage of a PC monitor, 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.

PC monitor electricity usage FAQ

Do monitors use a lot of electricity?

It depends on the monitor model, but, in general, monitors do not use a lot of electricity except for maybe very old models.

Find out the power usage in Watts of your computer monitor and use the calculator from the ‘Electricity cost calculator’ section to determine your monitor’s electricity usage and cost.

How much energy does a monitor use overnight?

You can use the calculator from the ‘Electricity cost calculator’ section to find out the energy usage of a monitor overnight.

Most monitors go into standby mode if unused and use much less energy. In general, the energy usage in standby mode is very small.

PC monitors and energy conservation

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

Reducing our PC monitors electricity usage, even a very small amount, would greatly impact preserving our natural resources.

For example, if 9000 households save as little as 10 Watts per day (0,01 kWh) on the electricity usage of our PC monitors, 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, pounds, or any other currency) per kWh, we would collectively save nearly 6000 euros annually.

> 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, small energy savings do count when looking into the bigger picture.
