How Much Electricity Does A Computer Use & How to Reduce the Electric Bill?

Computers have become a ubiquitous part of our daily lives, and as a result, they are one of the biggest consumers of electricity in homes and offices. A typical desktop computer uses between 60 to 300 watts, while a laptop uses between 15 to 60 watts. The amount of electricity a computer uses depends on various factors such as the type of computer, the size of the monitor, the processing power, and how much it’s used.

While computers are essential tools, their energy consumption can lead to high PESCO electricity bills. Fortunately, there are several ways to reduce the amount of electricity a computer uses and lower your electric bill. Here are some tips to help you save energy and money.

How Much Electricity Does A Computer Use

  1. Use power-saving settings: Most computers have built-in power-saving settings that can reduce energy consumption. These settings can be found in the control panel or settings menu. They allow you to adjust the computer’s sleep mode and other energy-saving features.
  2. Turn off your computer when not in use: Turning off your computer when you’re not using it can save a significant amount of electricity. Leaving it on for hours on end without any activity can consume a lot of energy.
  3. Use a power strip: Using a power strip for your computer and its peripherals can help you manage your energy usage better. A power strip allows you to turn off all connected devices at once, reducing standby power usage.
  4. Upgrade to energy-efficient hardware: When it’s time to replace your computer or other hardware, look for energy-efficient models. For example, a computer with an ENERGY STAR label uses less energy than a standard model.
  5. Adjust monitor settings: The monitor is one of the most power-hungry parts of a computer. Adjusting the brightness and contrast settings can help reduce energy consumption.
  6. Unplug unused peripherals: Unplug any unused peripherals such as printers, speakers, or scanners. These devices consume electricity even when they’re not in use.


In conclusion, computers are significant consumers of electricity, and their energy usage can lead to high electric bills. By using power-saving settings, turning off your computer when not in use, using a power strip, upgrading to energy-efficient hardware, adjusting monitor settings, and unplugging unused peripherals, you can significantly reduce your electricity usage and lower your electric bill. By making small changes to your computer usage, you can help protect the environment and save money at the same time.
