Electrons do not flow in conductors or semiconductors or anything else when a current is flowing. Yeah Yeah drift current... diffusion current... blah.
Charge is transported around the current path under the influence of the applied voltage.

Um, what about situations where the movement of electrons (or other charged particles) generates the voltage???

That's AC, not DC. Try to make Newton's cradle work in only one direction without a net movement of the balls through space.
thermistor-guy:
I guess the OP's point is that electron flow in circuits is rarely ballistic; in most cases, "electron flow" should be read as "net electron flow".
Yes, ok. EEs know that.

Not always. One example: a crystal radio set. Entirely passive, no voltage is applied to the circuit, rather a travelling electromagnetic field

Another example: solar cell with load. No voltage is applied to the circuit, just a travelling electromagnetic field at optical frequencies.

Other examples : thermocouples and thermopiles generating an electrical current due to a temperature difference.

Energizing a circuit does not always mean applying a voltage to it. There are other sources of energy. EEs know that. Hobbyists know that.

What about superconductors? 8)
