Yup, for a computer system, except whatever is emitted through light or
other RF wavelengths (radiant heat being just a band of wavelengths of
EM radiation), or electrical currents (very small, things like ethernet
connections).

Why, because they move?

Let's think about this for a sec, yes, to spin up a hard drive you are
using energy for something OTHER then generating heat. To keep the
platter spinning however you need energy to overcome the friction of the
bearing and the air in the drive. Friction = heat generation.

When you shut down the drive, the spinning platter eventually comes to a
stop. Why? The friction, so that energy you used at the beginning was
just temporarily stored in the movement of the platter. When the platter
spins down due to the friction of the bearing and air on the platter,
that stored energy is dissipated as heat.
