Ever wondered how much power is required to run a desktop computer or laptop? Freeware software Microsoft Joulemeter will give you the answer.
Joulemeter is a software-based solution that measure the energy usage of virtual machines (VMs), servers, desktops, laptops, and even individual software running on a computer.
Joulemeter estimates the energy usage of a VM, computer, or software by measuring the hardware resources (CPU, disk, memory, screen etc) being used and converting the resource usage to actual power usage based on automatically learned realistic power models.
Joulemeter can provide insight into just how much energy a computer is using when a physical power measuring tool is not accessible. Joulemeter can be used for gaining visibility into energy use and for making several power management and provisioning decisions in data centers, client computing, and software design.
