As discussed I have tracked my machine power with two scripts:

  • PowerHOG hogger
  • Stats.app

This is my data:

Format is

  • Stats / PowerHOG
20.08 21:00 227 Wh / 11.6 Watt hours - Pulled plug and inly in clamshell sleep
21.02 07:45 255  Wh / 12.15 Watt hours  - Plugged in always from here
22.02 07:45 371 Wh / 18.25 Watt hours 
23.02 07:00 484 Wh / 23.53 Watt hours
24.02 07:38 626 Wh / 29.03 Watt hours
26.02 07:00 881 Wh / 44.07 Watt hours
27.02 07:28 973 Wh / 48,37 Watt hours
28.02 06:21 1085 Wh / 57.96 Watt hours
02.03 10:30 1219 Wh / 65.42 Watt hours
03.03 08:18 1285 Wh / 67.93 Watt hours
05.03 07:10 1445 Wh / 76.14 Watt hours
06.03. 13:35 1565 Wh / 81.54 Watt hours
07.03. 07:51 1593 Wh / 82,19 Watt hours
08.03

Summary:

  • mac uses 3W in clamshell sleep ... I am suprised how much that is. Thought it was less
  • A normal working day is 3-6 W. That is than again suprisingly NOT much
  • Difference between PowerHOG and Stats is 10x that is heavy and gives a strongly distorted picture of the totals at least. Sadly it also shows how irrelevant the CPU, GPU and RAm is in normal office working conditions compared to WiFi, Display, Bluetooth and ports ...

+1 on integrating total machine power still and re-distributing it as overhead to the processes
