It can use MJ or EU.

The green bar has no use (this could be a bug). In other machines, when it gets to the top, it will 'do' whatever the machine is meant to to.

For example... when the green bar gets to the top in a Composter it will produce one Industrial Fertilizer (then the bar will drop to zero and it will start again).

It's from the MineFactory Reloaded mod.
