Which Monitor Is The Most Energy Efficient? (Answered)

In a world of rising energy costs, we must try to save as much energy as possible. Monitors are some of the most used tools in our homes and finding one that is energy efficient is a great way to start reducing your energy costs. It is important to understand which monitor is the most energy efficient.

The Dell G2210t is one of the most efficient monitors when it comes to consuming energy and features a large 22-inch display. EnergyStar rates the Dell G2210t at around 22 watts when active. However, it is a mere 0.12-watts when the monitor is in sleep mode or offline. This makes it one of the most energy-efficient options on the market today.

How Does Energy Efficiency Work In Monitors?

To better understand energy efficiency in monitors, we should look at how the rating system works. No matter which monitor you buy, you will find that an energy label is often attached, which shows the average energy consumption per 1000 hours of use. Here is how energy efficiency works:

Energy RatingAverage Kilowatts Per 1000 HoursAverage Annual Energy Consumption (kWh)

As you can see, the rating on your monitor would indicate how much energy the monitor is using and this would be a great indicator of how much it would cost and use over a year. You must choose one, which does not consume as much.

Which Factors Influence Energy-Efficiency?

When it comes to monitors, experts have analyzed numerous aspects of the monitor to show you which aspects affect energy efficiency. If you want to know how energy efficient your monitor is, the following factors should be kept in mind.

  • Screen Size: The bigger the screen size, the more power your monitor will need to keep it going. However, this will be worked out depending on the consumption of power per inch and not the total size of the screen to bring it into perspective.
  • Kilowatts Per Hour: The number of kilowatts per hour is self-explanatory and refers to how much power the monitor would use within one hour. The value is often measured in kilowatts.
  • Active Power Consumption: This refers to how much power the monitor is using while it is active. The number will be expressed in wattage.
  • HDR Support: The final aspect refers to the power consumption of the monitor when various accessories and support systems have been integrated.

Once all these numbers are put together, you should get a clear indication of how energy efficient your monitor should be. The more energy efficient it is, the better your rating would be.


Nowadays, the price of energy is rising at an astronomical rate and the main goal for households will be to reduce consumption to as much as possible. Buying an energy-efficient monitor is the best way to ensure that you can save some power each year. Let us know in the comment section which energy-efficient monitor you prefer.
