It would be valuable if you could indicate which of the possible
definitions of "*NET* energy moving" you mean.

Net energy is the difference between the average forward
energy and the average reflected energy. Please forget
instantaneous values. Instantaneous voltage and current
are obviously valuable concepts. For the context of this
discussion, seems to me instantaneous energy or power are
just diversions away from the real issues.

The real question is: Can an EM wave exist without energy?
Roy implies that it can. I challenge him to produce an
EM wave containing no energy.
