I’m between radiant energy to mechanical and kinetic energy to mechanical

The energy in wind CAME from radiant energy originally, but it isn't
radiant energy any more.  It's the energy in the mass of moving air,
and that's KINETIC energy.

You could move the turbine blades with stones or pingpong balls,
push the blades with your hands, or shoot water at them from a hose. 
In any case, you'd have moving mass with kinetic energy transfer that
energy to the turbine.  A moving mass of air does the same thing.
