Track PC Power Consumption With Microsoft Joulemeter : " Tracking a PC’s or Laptop’s power consumption can be helpful in several ways. It can for instance be used to analyse power usage to reduce the energy bill or find ways to increase a laptop’s battery life by reducing the overall power usage. Microsoft Joulemeter is an experimental program for Windows that can track the PC power consumption. It is compatible with desktop and mobile computers. The application places an icon in the Windows system tray on startup. A click on that icon displays the main interface where the power consumption and statistics are displayed and constantly updated. The power consumption is divided into base, cpu, disk and monitor which are added to get a total power consumption. The application currently is not measuring the gpu’s power consumption which – on modern computer systems – uses lots of power. It also has to be noted that the values are estimations if the application is installed on a desktop
