It would be valuable if you could indicate which of the possible

Net energy is the difference between the average forward
energy and the average reflected energy.

Okay. Option 2. This is the same as subtracting
the indications that a Bird wattmeter would provide
for the forward and reflected power.

I like this definition for NET energy transfer.

Please forget
instantaneous values. Instantaneous voltage and current
are obviously valuable concepts.

Now the next question. When the instantaneous power
is always 0, is any energy transferred?
