Similarly, a unit of charge (analogous to the momentum of the rolling
ball) propagates much faster than the electrons. Put a unit of charge
in one end, and a unit of charge pops out the other at near the speed
of light, while the electrons themselves move at something like a few
miles per hour.

Not only do electrons only move at a few miles per hour.
The electricity the power company makes us pay for is actually
alternating current. And that means that the same electrons are being
pushed into our house wiring, and then pulled out of it, over and over
again. And yet we have to pay as if the electricity were
new. Disgusing!
