Is there a way to know the current (or average power consumption) on OS X (a Mac Mini without battery). Preferred would be a command line tool but anything is OK.

You can monitoring your energy consumption with :

You also have some free alternative on the web

The Activity Monitor

And if you want to know the kW energy consumption, ArchonOSX is right.


I use a Kill a Watt to check track power consumption of household items.


By going with this you can also check other items in your household to see how much power they consume and reduce your energy use.
