Circuit Energy doesn't FLOW the way you THINK!
Why Physics Stack Exchange recommends it
Physics Stack Exchange users link it when someone asks how energy actually moves in a circuit, since it introduces Poynting vectors and field-based energy flow in an accessible way.

What it is
A short explainer from The Science Asylum arguing that energy in a circuit does not travel along with the electric current. It uses the Poynting vector to show that power flows wherever electric and magnetic fields coexist, and walks through the surprising consequences for a simple battery and resistor circuit.

PS: This qualifies as "adding new info" but it is unrelated enough to go in a comment. Here [this video] is an edutainment video talking about how energy flows in a normal circuit with the fields involved. It talks about Poynting vectors, ambient fields, idealizations made to better analyse circuits etc and other stuff that other comments and answers mentioned. Thought you might be interested.

Not a full answer, but you might benefit from this video explaining how energy flow actually happens in a circuit [this video]

I think that the circuit which I took from this video [this video] assumes positive charges as the current is flowing clockwise in the video.

I have recently watched two YouTube videos on this subject, that you can see here (first by "Science Asylum" and the other by "Veritasium"). [this video] [LINK] So, both videos ask the viewer to imagine a simple circuit, a battery connected to a resistor (such as a light bulb). As the battery is connected in the circuit, it will cause the electrons in the wire to drift away from the negative terminal of the battery, dissipate energy in the light bulb and then be attracted into the positive terminal. Veritasium video shows though that one shouldn't really think of this as some kind of "domino" effect for electrons, but rather as an EM wave propagating directly from the battery to the light bulb, a
