No they don't, and...

Changing the energy in a TEM wave to heat is obviously a transfer of
energy. Radiating TEM energy from an antenna is obviously a transfer
of energy. When TEM wavefronts are destroyed by wave cancellation in
a transmission line, they cease to exist and must therefore transfer
their energy somewhere. There is simply no other possibility.

At an impedance discontinuity match point with reflections, the
destructive interference energy is transferred in phase to the
constructive interference event occurring in the other direction.

What *exactly* is your definition of a "wave"?

"traveling wave - The resulting wave when the electric variation
in a circuit takes the form of translation of energy along a
conductor, such energy being always equally divided between
current and potential forms." i.e. P=|V*I| and Z0=V/I
