No, in a propagating transverse electromagnetic
wave may be orthogonal, but they are in phase.

In a vacuum they are in phase. As a medium in
interposed, the phase relationship changes.
When bound to a conductor, and "pushing" charges
around, they are 90 degrees out-of-phase.

From my knowledge on power generation, the electric
and magnetic fields are 90 degrees out-of-phase
if no mechanical energy is converted into electric
power.

That is what pushing electrons (with their mass... remember simple
harmonic motion?) does.

When you are pushing electrons, like if it were
an harmonic motion, you are pushing reactive
power only, back and forth, without any energy
loss, nor any energy converted.
It's harmonic motion of a system at its natural frequency.
It's a coil+capacitor set up (zero resistance).
It's a motor without rotor.

To really push electrons out of the system and
generate net electricity (real power on a resistor
P = R I^2 for instance) you must move towards a
situation where the electric and magnetic fields
become in-phase.

Only in-phase you got zero reactive power and
100% real power converted.
