計一下你的電腦用了幾多電


Li個MINI Software 可以幫你計算你的電腦在每一秒用了幾多電,還有排放了幾多立方尺的二氧化碳。

這是我不斷開Photoshop CS5 個半小時的用電和碳排放(1.15 立方尺而已,我想我家中的一盤鐵樹一個星期已經吸完了)。而我的電腦平均用電只有120W呃!!!

Information on data displayed
Power Consumption:
BASE: The minimum power drawn by this computer when powered on.
CPU: Additional power drawn depending on CPU utilization (changes with processor workload and frequency).
Disk: Additional power drawn due to disk activity (changes with IO workload)
Monitor: Additional power drawn by the monitor (changes when monitor turned on and on laptops with LCD brightness).
Total: Total current power drawn.
Average: Average of the total power drawn over time, since installation of Joulemeter.
Power Consumption (from default model) implies that power data is estimated using generic power usage assumptions, based on typical usage for type of machine (laptop, desktop).
Power Consumption (from learned model) implies that power data is estimated using a model specific to your machine and is more accurate. See “Calibration” instructions.
Statistics (since …) measures accumulated usage since the specified time.
Time Slept includes time when the machine was in Sleep, Hibernate, or Shutdown modes. Power usage in these modes is negligible for most machines.
Time Awake indicates the total duration for which the machine was on.
Estimated Consumption indicates the total energy used by the machine. The error in the estimate depends on the power model used. The error is low when the Power Consumption section shows “from learned model.”

Calibration
Learn a power model for your machine to get more accurate power data. For laptops, when the battery is at least 75% charged, disconnect the power cord. For desktops, connect a WattsUp meter (see instructions at the project webpage). Then, go to the Windows Start button, find the Joulemeter folder in your programs, expand it, and start Joulemeter Calibration.
