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!

Electrons DO move quickly in a conductor
but most of that motion is in random
directions. Electron drift, the motion
of particular electrons from one end of
a conductor to the other, is slow as
described.

FWIW, for most AC appliances and their
conductors, electron drift may be so
slow that electrons entering one side of
the plug never reach the other side
before a polarity reversal of the AC.
