With a car, the engine converts some of its energy to
kinetic energy, which is subsequently dissipated as heat,
so it makes sense to talk about the ratio of kinetic
energy produced to energy wasted directly as heat.

But when you flip a bit, there's no intermediate form
of energy -- the bit changes state, and heat is produced.
So all of the heat is waste heat.
