How To Adjust Your Computer’s Energy Consumption

If you own a computer, you know that it is basically an electrical power generator that runs all of your favorite games and applications. But what you may not realize is that the more power you use, the more energy your computer will generate. Think of it like a car—the more you drive your car, the more gas you use and the more power your car generates. The same goes for your computer. Not only can you lower your computer’s power consumption by adjusting its settings, but it can also be improved by using different energy sources.

Computer energy consumption is a double edged sword: It’s necessary to provide power to your computer, but it also contributes to energy waste. Turning off unnecessary services, shutting down unused programs, and switching off unused hardware can help to reduce energy consumption in your computer.

If you’re like me, your computer is the first thing you see when you wake up and the last thing on your mind before you go to sleep. However, what you might not know is that the computer you use can have a huge impact on your energy usage. Computer power consumption is measured in watts (W), and understanding the power consumption of your computer can help you balance it with your budget and personal usage.. Read more about how to adjust computer energy consumption and let us know what you think.

Not only will being able to modify your computer’s energy usage help you save money on your electricity bill, but it will also help your laptop live longer between charges. This post will demonstrate how to do so.

Computers are an indispensible element of contemporary life, with at least one computer in almost every home and business in the United States.

However, these devices use a tremendous amount of energy and electricity. The typical desktop produces the same amount of carbon monoxide as a vehicle traveling 820 miles in a year. So, if you need to use your computer every day, how can you decrease the amount of energy it consumes?

Dim the brightness of your computer and configure it to go to sleep mode after ten minutes of inactivity to reduce its energy usage. It’s also a good idea to unplug or switch off external equipment like printers or speakers when you’re not using them, and to shut down your computer once you’ve finished using it.

A few easy changes to your settings and how you operate your computer may drastically reduce your energy use. Although most new computers are pre-programmed to utilize the most effective settings, you may customize them to fit your workstyle and computing requirements.

This tutorial will teach you how to make your computer run more efficiently. 

How To Adjust Your Computer’s Energy Consumption

Make changes to your computer’s settings.

The first location to reduce your computer’s energy usage is in its settings. These settings allow you to adjust the brightness of your screen, the volume of your music, and the length of time your computer remains on and active while you aren’t using it.

Most computers, whether for personal or business usage, do not need to be switched on on a regular basis. Allowing your computer to shut down or enter sleep mode when you aren’t using it is the greatest setting for your computer since it lowers the amount of power it consumes while it is operating. 

You may change your computer’s settings manually or utilize the pre-installed energy saving options. Understanding how all of the changes operate will help you make energy-saving choices every day. Your computer’s requirements and energy output may vary from day to day, so knowing how they work will help you make energy-saving decisions every day.

Another easy change that has a significant effect is lowering the monitor’s brightness. Saving electricity and avoiding eye strain may both be achieved by lowering the brightness to the lowest comfortable level. Even lowering the brightness a few notches from maximum can help. 

When utilizing battery power instead of a power adapter, certain models allow you to configure it for laptops so that the screen dims automatically. Otherwise, you may use your keyboard or the settings menu to manually change the brightness. The less screen brightness you require, the darker the room. 

The brightness settings on a desktop computer are typically located on the display. You may adjust them similarly to a laptop, only utilizing the brightest settings when you’re outside in direct sunlight.

To save energy, consider shutting off the display even if the CPU is still running or in sleep mode. 

Modes of Standby and Sleep

Standby and hibernation modes, often known as sleep modes, are available on all computers. These are methods for your computer to cease consuming power without fully shutting down.

This allows you to immediately resume work after a period of inactivity while also providing the energy savings associated with shutting down an idle computer.

The terms “standby,” “sleep,” and “hibernate” all have somewhat different meanings. They may indicate that your computer is in an energy-saving mode or that it is effectively switched off, depending on your machine and operating system.

Hibernation is the process through which your computer saves your work and then shuts off. Any applications that were running before hibernation will restart when you switch it back on. 

Standby mode significantly reduces the amount of power used by your computer while not completely shutting it off.

The screen will typically go to sleep, but the hard disk and other applications will continue to operate, although at a reduced capacity than while the computer is in use. This allows you to restart your computer faster than while it is in hibernation mode. 

Operating systems now allow you to choose how you want your machine to save energy. You have control over how long different parts of your computer will be operational.

You may, for example, configure the screen to go to sleep after 10 minutes of inactivity while keeping the hard drive active until after 15 minutes. 

Getting to the PC’s power-saving mode

If you’re using a PC with a Windows operating system, the Control Panel gives you access to all of your energy-saving options.

Depending on whatever version of Windows you have, you may see a System and Maintenance or Performance and Maintenance option, or you may go directly to Power Options. You’ll be able to choose Power Options from the Maintenance menu if you have one. 

Power Options allows you to choose how long your computer should remain idle before shutting down.

Energy-saving options are already activated on newer computers, but you can tweak them to fit your work style better. 

For Macs, gaining access to power saving

In Mac, go to System Preferences and find your energy settings. For Energy Saver, click the lightbulb symbol. If you’re using a laptop, you may adjust the battery and adapter settings.

You won’t have that choice on a desktop. You may change the sleep time, when the hard drive goes down, and when the screen dims using this option. 

You can also use the schedule button to establish wake-up and sleep hours for your computer. This is a good method to make sure your computer saves energy even if you forget to switch it off after you’re through using it. 

Remote desktop access

When you use a remote desktop, you won’t switch your computer off when you’re not using it. You must keep the local desktop you’re connected to turned on in order to connect to it.

However, you do not need to keep that machine’s monitor switched on. Even though the CPU will essentially operate 24 hours a day, this will save some energy. 

Make sure you’re saving energy and lowering your energy usage on the PC you’re using to access the remote desktop when you utilize it.

If you’re using your laptop at home to access your office’s desktop computer, for example, make sure your laptop is saving as much energy as possible to compensate for the energy used by the desktop computer. 

Get rid of the screensaver.

Screensavers were a common feature on early computers to prevent pictures from being permanently embedded in the screen. Screen technology has advanced much since then, and screensavers are no longer just useless, but also a waste of energy.

A screensaver prevents your computer from putting any of its systems to sleep. To show the pictures, the screen and hard disk must operate constantly. Remove your screensaver completely to reduce your computer’s energy usage. 

You may disable your screensaver in Windows by right-clicking the desktop, going to Properties, and changing Screensaver to None. Go to System Preferences, Desktop and Screensaver, and set Screensaver to Never on a Mac.

When not in use, unplug all accessories.

Turning off and unplugging devices when not in use is another easy method to reduce your computer’s energy usage.

Even when you aren’t using them, printers, external speakers, external hard drives, and even ring lights may use power.

Turn off and unplug your accessories as much as possible to avoid the phantom drain that these gadgets create. Phantom drain occurs when a gadget is connected into the wall and uses power even when it is turned off.

Devices that do this are known as “energy vampires,” and they may consume as much power while they’re not in use as they do when they’re on. 

You can prevent phantom drain by unplugging each gadget from the power supply as soon as you’re through with it.

Smart plugs and power strips, on the other hand, may offer you the control you need to turn off power to specific devices without having to fiddle with wires and connections every time you need to print anything.

Newegg’s Kasa Smart Power Strip is an excellent option for your computer station. It includes standard jacks and USB connections for connecting your computer and all of its peripherals.

The strip includes a timer function, and each socket may be controlled separately, allowing you to switch off your printer without turning off your computer. 

Bluetooth and WiFi are both available.

Bluetooth and WiFi are two additional battery-draining computer devices. You can turn them off if you don’t need them to conserve energy.

Even if you aren’t connected to the internet or utilizing Bluetooth, they use power when in standby mode. They won’t use any power if you turn them all the way off, and they’ll come on fast and effortlessly when you need them again. 

Apps and software

Any software or application you run on your computer consumes electricity. Audio and video programs that are effective tend to consume more power, while apps that utilize an internet connection are the most power-hungry. 

It will also assist if you choose applications that consume less energy. Some internet browsers, for example, are more efficient than others. The Opera web browser includes energy-saving capabilities such as stopping activities in tabs that aren’t being used. 

Instead of working directly in the web-based platform, you may work on projects using local applications and subsequently copy them into web-based platforms. You may use Word without an internet connection, for example, which saves energy.

When you need to utilize the web-based capabilities, you may transfer your data into a Google Doc. Many Google products may also be used offline, which saves energy. 

When you’re not using them, applications and programs consume power in the background, much like wifi, Bluetooth, and your computer accessories. When you aren’t using a software, shut it down. This will not only conserve energy, but it will also improve the performance of your computer.

If you only want applications to run when you open them, rather than every time your computer starts up, you may read my other post, which explains how to deactivate specific programs on startup.

Many of the power-saving actions will also help your computer run at its best, so you’re not just helping the environment; you’re also benefiting yourself!

Use the BIOS functions on your computer.

You can utilize the BIOS features if you have a bit more computer knowledge and wish to go beyond the Control Panel settings. BIOS features are available on every Windows-based computer. 

When you turn on your computer, press the appropriate function key to access these options. It will display the power settings for the machine.

This page allows you to customize and activate sleep settings based on your preferences. You may use this menu to activate sleep settings while your laptop is closed. 

These options are more specialized than those found in the Control Panel menu.

If you aren’t a computer specialist and don’t understand BIOS operations, the normal menus may still affect your computer’s energy usage.

Tips for conserving energy

Turning off things you aren’t using whenever feasible is the greatest way to save energy. Using just what you need, when you need it, can increase the efficiency of your computer and prolong its life. 

It’s difficult to change old habits, so set reminders or connect your system to a power strip with a timer if you have difficulty remembering to shut off applications or power down your laptop at the end of the day.

You don’t have to be a computer genius or a coder to save energy. You must be familiar with your computer’s operating system as well as your personal work habits. 

Desktops vs. notebooks and laptops

Laptops are the best choice when it comes to determining which kind of computer consumes the least amount of electricity. Desktop computers use considerably more energy than notebook or laptop computers.

Part of this is due to the lack of a battery option on desktop computers. They’re also usually bigger and less efficient. When choosing between a notebook and a desktop, the laptop is the most efficient choice. 

Laptops are typically more expensive up front, but they will save you a lot of money in energy expenses over the course of the machine’s life. Despite the fact that they are inherently more energy efficient than desktop computers, it is still necessary to adopt energy-saving measures. 

Rather than keeping your laptop plugged in all the time, just charge it when you need it. This will assist to eliminate any phantom power use.

Also, unless you’re utilizing timers or smart plugs, don’t leave the adaptor plugged in. Many laptops offer specific energy-saving options to help you get the most out of your battery.

You may save even more electricity by simulating those settings while using your power adapter. 

Make improvements to your machine.

Reducing your computer’s energy usage isn’t a one-time event that occurs when you change the way you use it.

It’s crucial to think about the computer you buy and how you’ll dispose of it after it’s no longer functional. You want to choose a machine that uses less energy over its whole lifetime. 

When it’s time to replace your computer, search for one that complies with both the Energy Star and EPEAT guidelines.

Energy Star devices must adhere to strict power consumption guidelines. All Apple machines, as well as the overwhelming majority of PCs, fulfill these requirements. 

EPEAT standards don’t only check at machine aftermarket power usage. EPEAT-certified computers are designed with the environment in mind throughout their entire lifetime.

For EPEAT certified goods, the production process is greener, the operation is more efficient, and the recycling of broken equipment is simpler. 

If you have a desktop computer, you can generally replace components of it for less money than purchasing a new machine.

You may replace your hard drive, RAM, and even your motherboard with more energy-efficient models, prolonging the life of your computer while also lowering your energy usage. 

Look for a recycling program when your computer stops working. Many municipalities provide recycling days or pick-up services for old electronics, including computers, to be properly recycled.

To safeguard your data, make sure you clean the hard disk or remove it first. 


Computers are an essential aspect of contemporary life, but they don’t have to be energy guzzlers. If everyone makes modest changes to how they use their devices, we can save a significant amount of energy. 

To reduce energy usage, you may make a number of easy changes to the way you use your computer.

Modern computers are built with energy efficiency in mind. Even so, you may improve efficiency even further by tailoring your machine’s power settings to your work style and shutting off accessories and apps when not in use.
