As you increase intensity, in general, the total amount of energy you
burn increases, but the absolute amount of fat increases *to a point*
then stops increasing. So the percentage energy from fat decreases at
higher intensity, but you still burn just as much (roughly, yes Tam, I
know ....) fat per hour.
So yes, you burn fat effectively ni z2/E2/whatever higher zone you
define, but you burn more sugar and glycogen as well.
