Of course, the IEEE makes no such contention. Only by
careful selection of the words you choose to see can
this claim be made.

The IEEE definition of "power-flow vector", from
IEEE 100, "The Authoritative Dictionary of IEEE
Standards Terms", Seventh Edition, opens with:

"Vector-characterizing energy propagation caused
by a wave"

Seems like they pretty much have it right. The
definition continues with:

"and giving magnitude and direction"

Yes, it is a vector. And the definition concludes
with:

"of power per unit-area propagating in the wave
(i.e., analogous to Poynting vector)."

Yes, they could have substituted "energy per
unit-time" for "power", but, given the complete
context, clarity would not be enhanced and the
sentence would be much more awkward.

Only someone skilled in the use of sentence
fragments would claim that the IEEE contends
that "power propagates in a wave".

Methinks you owe the IEEE an apology.
