Choosing an energy-efficient monitor is an important step to take in reducing your carbon footprint. Each monitor listed meets Energy Star standards and is available on Amazon.

Computers are a necessity in today’s world, but they can also be very hard on the environment and your electricity bill. Computers use a lot of energy and create a lot of waste.

There are ways you can use energy more efficiently by selecting the right types of monitors for your computer and using them properly. In this blog,
We will look at the top 5 energy-efficient computer monitors on the market today.

The U.S. Environmental Protection Agency (EPA) estimates that a home computer uses energy at a moderate level. People who are concerned about their carbon footprint may find consolation in knowing that it takes around 400 kilowatt-hours (kWh) per year to power a typical computer setup. Thus, 530 pounds (240 kilograms) of carbon dioxide are emitted along with approximately $35 in electricity costs.

Computers often use more energy than other devices, so it makes sense that they would also be at the top of the list when it comes to efficiency talk. When it comes to monitors – especially LCDs – a source [Energy Savers] reports that up to 90% of their electricity goes toward keeping your monitor optimized for the current task in front of you.

So, whether you’re printing a document or playing an online game, your monitor’s actually on more than you’d expect; this is regardless if you’re using your computer for personal or work-related duties, including web browsing as well as putting spreadsheets together and/or writing emails.

Our goal here is to help aware people save energy by switching out older equipment or buying products with a specific commitment to energy efficiency.

Energy efficiency is not a selling point for most people when they are shopping for a computer monitor. Often, the primary considerations that consumers have when choosing a computer monitor are its size, refresh rate, display quality, and connection options.

However, if you’re an eco-conscious buyer, you might want to take a look at these top 5 energy-efficient computer monitors, which range in size from 15 to 28 inches and feature low power consumption and high display resolution.

Energy Efficiency And Your Computer Monitor

You can affect the amount of power your computer monitor uses by buying the smallest monitor you can live with; turning off the monitor when it’s not in use; enabling power save options (which only put your computer to sleep after a period of no activity), and choosing an Energy Star certified display.

By enabling the monitor’s power management feature and turning your monitor off at night, you can ensure optimum power efficiency. Not only will this save money and electricity, but it will also help keep your monitor from overheating, thus prolonging its lifespan! Energy Star-certified monitors use 30-60% less electricity than standard models and are one of the easiest ways to earn your green computing credentials.

According to Energy Star, if every monitor on sale in the US met its specifications, “the energy savings would grow to about $1 billion each year and prevent greenhouse gas emissions equivalent to those from nearly 1.5 million vehicles.”
