There is only one correct answer to that question.
The electrical energy either flows through wires or outside them.
Since electrical current is defined as a stream of electrons (unless anyone thinks that definition is wrong) and electrons travels through wires electrical energy also travels through wires.
There is absolutely no evidence to suggest electrical energy travels outside the wires.
Free electrons traveling closer to the surface of the wires or even outside surface of the wire will still be considered inside the wire.

Derek has no idea what a capacitor is and completely ignored the line capacitance which was responsible for the effect he observed immediately after the switch was closed.
Even just moving the switch without closing the circuit will have created the same effect.

Hard to argue with that.

Wrong.

You are endlessly repeating yourself.

As am I, I guess.  >:(

That's some pretty lazy flip-flopping between current and energy there, (again)...

Well what is the evidence ?  I have not seen any.
The only argument Derek had was energy flowing through lamp witch in itself is just a wire (electrical conductor) about 3ns or so after the switch was closed.
And it is not about how close is the battery to the lamp but how close are the wires that form the line capacitance together.
In fact the battery can be moved 10 or 20m away with all the other components in the same place and it will still be about 3ns before some current will flow through the lamp.
Same problem with the switch. If all is the same and the only thing you move is the switch location that will influence the time it takes for a current to start flowing through the lamp even tho the position of the lamp and battery is unchanged.

If the switch is all the way on the moon and the battery and lamp are 1m apart here on earth when switch is closed there will be a current flow through the wire starting on the moon but there will be no current through the lamp until about the time it takes light to travel that distance 95% or of the speed of light.

What part you disagree with ?

a) electric energy is the electric power integrated over time.
b) electric power is the product of electric potential and electric current.
c) electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.

The c) is copy paste from wikipedia (first line in a google search).
