EM wave energy necessarily travels at the speed of light.
There is exactly the amount of EM wave energy contained

reflected power.

You are not suggesting that the energy contained in a transmission
line in the steady state in the general case is constant, are you?

Obviously, a leading question. :-) I'm not talking
about instantaneous values here. All my statements
apply only to values averaged over an integer
number of RF cycles in one second.

This gets confusing. You are talking about "the amount of EM wave energy
contained in a transmission line" and now you qualify it with "values
averaged over an integer number of RF cycles in one second". Average
energy over time is POWER... are you talking about power and foxing us by
calling it energy. I am confused.
