How to Make a Computer More Energy Efficient

How to Make a Computer More Energy Efficient
Computers are devices that are often used in daily activities such as work, study, or even entertainment. Even though it looks profitable, ineffective use of computers will increase energy expenditure and electricity costs that must be incurred. Therefore, this article will explain ways that can be done to make your computer more energy efficient.


How to Make a Computer More Energy Efficient

1. Using a CPU with the Right Specifications

Using a CPU (Central Processing Unit) with the right specifications or as needed can help save energy on the computer. CPUs with larger or more powerful specifications usually require higher power to operate. Therefore, choosing a CPU with specifications that suit your needs can help reduce energy use on your computer and save on energy costs.

2. Clean the Inside of the Computer Periodically

Cleaning the inside of your computer regularly can help reduce your computer's energy use. Dust or dirt that accumulates on the inside of the computer can make the fans and coolers work harder, requiring more power. In addition, dust that accumulates on the electronics inside the computer can also cause overheating and slow down computer performance. Therefore, make sure to clean the inside of the computer regularly to maintain performance and save energy usage on the computer.

3. Disabling the Monitor Screen in Standby Mode

Another way that can be done is to turn off the monitor screen in standby mode when it is not in use. Be sure to choose the right and appropriate settings for power management to save energy when the computer is not in use.

4. Updating Drivers

Often the drivers on the computer are often not updated and cause greater energy usage. The use of improper drivers causes the computer to work not optimally, causing more energy use. Make sure to always update laptop and other device drivers so that energy use will be more effective.

5. Not Using Screensavers

Screensavers or screen saver applications are made to eliminate burn-in on the monitor screen. However, using a screensaver requires more energy than when the monitor is in standby mode. So, make sure to turn off the screensaver immediately when not in use.

6. Optimizing Laptop Settings

Laptops are often used by many people when traveling. To extend battery life, be sure to optimize laptop settings to make it more energy efficient. One way that can be done is to use airplane mode when you are not using the internet and reduce the brightness on the laptop screen.

7. Disabling USB Ports

Computer by default will enable USB Ports continuously. Though the use of USB Ports requires the use of energy. Therefore, when not in use, make sure to disable USB Ports on the computer.

8. Reduce Screen Brightness

Reducing the screen brightness can help save energy when using the computer. A screen that is too bright or with a very high brightness can drain the battery more quickly and cause greater power consumption. Therefore, it is recommended to reduce the screen brightness when not in use and change the power saving mode to energy saving mode. Screen brightness settings can usually be found in the settings menu on a laptop or monitor.

9. Turn off the computer or laptop when not in use

Turning off your computer or laptop when not in use can help save energy significantly. When a computer or laptop remains on but is not in use, energy will continue to flow and drain battery or electricity. Therefore, make sure to turn off your computer or laptop when not in use for a long time. Also, make sure that your laptop or computer is in sleep or hibernate mode when not in use so that less power is used. These methods can help save energy use on computers or laptops so that they can help save energy costs and protect the environment.

10. Using LED Screen Monitors

Using an LED screen monitor is a great way to save on energy usage on your computer. LED screen monitors are known to be more energy efficient than CRT or LCD monitor types. In addition, LED screen monitors also have a higher brightness level, better image clarity, and more accurate color display. By using LED screen monitors, we can save energy usage up to 45% compared to other types of monitors.

11. Using LED Lights

The use of LED lights can also help save energy. LED lamps are known to be more energy efficient and have a longer lifespan compared to other types of lamps. LED lamps use only 20% - 25% of energy compared to incandescent lamps. In addition, LED lamps also do not contain mercury which is harmful to human health and the environment. By using LED lights, we can save energy usage while using a computer, so that it can help save on electricity costs that must be incurred every month.

12. Turning off the computer when not in use

Turning off the computer when not in use is the best way to save energy. Without turning off the computer, the computer will continue to consume energy even when not in use. Be sure to always turn off the computer after use to save energy.

13. Using Multi-Plug Sockets

The use of multi-plug sockets can help save energy usage when charging device batteries such as laptops, smartphones or tablets. By using a multi-plug socket, we can connect several devices at once and turn them off when not in use to save energy. In addition, the multi-plug socket also helps to avoid overuse of the charger, which can help save energy and extend the device's battery life.

14. Optimizing Computer Use at Certain Times

In addition to the methods described above, using a computer at certain times can also help save energy. Working or using a computer during the day when the sun is bright enough can help save energy because there is no need to turn on the lights. In addition, make sure to adjust your computer usage to a certain time. For example, avoiding using the computer at night because at that time, the energy requirements for lighting can be quite high.

15. Using Programs to Regulate Energy Use

Programs for optimizing energy use on computers such as Ecosaver or Local Cooling are good solutions for saving energy use on computers. This program can help manage and monitor energy consumption on a computer. In addition, these programs can also help optimize energy use on computers automatically and reduce the need for energy use significantly. By using these kinds of programs, we can help maintain efficient energy use on computers and save on electricity costs.


In this article, we describe ways you can make your computer more energy efficient. By implementing a few simple steps such as using an LED screen monitor, updating drivers, and disabling USB Ports, we can help save energy usage significantly. In addition, updating the operating system and optimizing laptop settings can also help ensure efficient use of energy on the computer. That way, we can save on electricity costs and complete tasks more effectively and efficiently.
