Actually electrons do not do much of anything when it comes to electricity.
The actual charge (or energy or sea of physical photos) is outside the wire!
The wire is only used as a primer to set up the "field"or "potential" both non physical descriptions of a physical thing.
Charge flow is actually physical photons that move, usually from a place where there are a lot (high potential or +) to place where there are less (low potential or - ), this is a very simplistic explanation on purpose.
A good example wireless energy, no wire, no electrons, just photons.
I hope this helps.
