What is the speed of "electricity"?
For most of the copper wire and traces you see, about 60% the speed of light in a vacuum. The energy is the signal so they are the same.

The speed of electrons is much slower...slower than walking pace. The electrons aren't moving to and from the powerplant 60 times per second.

Think the difference between the speed of sound and the wind. The wave (energy) moves through the medium much faster than the medium itself.
