Joulemeter – Free Software that Monitors Power Usage of Computer

Joulemeter is free computer software that will monitor power usage of your computer, as well as tracking your monitor, disk activity as well as your CPU. It also calculates your Co2 emissions. It was created by Microsoft Research labs. This measures all the energy that your computer uses day by day as well as being able to calculate the amount of power that is required by desktops, virtual servers and other types of computers. This is a simple and easy to use program for your computer to monitor your energy usage.

The Joulemeter project is developing methods to improve the energy efficiency of computing devices and infrastructures. It provides a modeling tool to measure the energy usage of virtual machines (VMs), servers, desktops, laptops, and even individual software applications running on a computer. The visibility provided by Joulemeter is being used to improve power provisioning costs for data centers, virtualized power budgeting, desktop energy optimizations, and mobile battery management.

How to Use Joulemeter?

Simply install it into your computer and you are ready to go. It will constantly monitor all phases of your computer and hardware that is switched on. It tracks how much energy it will use as well as giving you three tabs to work with. When you are talking about the disk and the monitor, these changes will fluctuate depending on the use of your computer. The program tells you what is using how much power and what your potential power usage will be.
