Answer offered is an assertion still dodging the question of where
claimed lost energy might go. This is not a response worthy of an
annointed scholar.

Well certainly you have power (err...that's not energy...so just go
integrate will ya?) dissipated in the compressor as it compresses the air,
and you likewise have a cooling at the regulator... the power lost in
turbulence (and moving the whatever downstream from it, that is, any
mechanical work, such as a tool, or blowing along more air if it's an open
leak) is where the actual power flows from input (mechanical compression) to
output.

That seems obvious enough to me.
