The movement of electrons does not produce energy. The movement of electrons is caused by energy. Electrons can also transfer, absorb, and release energy.
That is a peculiar statement to make. It is not wrong, but different. Voltage is the energy density of the charge. Therefore saying that voltage is necessary for energy is like saying that density is necessary for mass. I suppose you can say that space or volume is also necessary for mass.
@ alsia
fundamental law of conversation of energy
"energy cannot be created or destroyed ,it cant only be transformed from one form to another"
so electrons movement doesnot produce energy, but utilize energy .
Please quantify your energy. If you need to express an amount of energy, you must use a scientific unit of energy. I chose electron-volt because the OP is talking about electron charge. What units are you using?

ooooh, ooooh, ooooh, "This energy is released as the charge, in Coulombs, moves (usually through some form of resistance) from higher to lower voltage." higher to lower via gravity? more to less, or electron flow or conventional flow? I know, don't go there.
Not the total energy like translational or rotational energy. Just the energy it took to accumulate the electrons into one spot. When the electrons disperse, they will give up that energy.
You misunderstand. "W" does not stand for "watts". "W" is the scientific symbol for energy, joules. Power, in watts symbol is "P". I guess the standard came from the use of "W" for Work, which physics terms, is the same as energy.
That's V(Voltage in volts) =(equals) W(energy in joules) /(per) Q(unit of charge in Coulombs)
Yes indeed, W is the energy required to concentrate that charge. Not "energy density per unit charge". Just plain old energy per unit charge. If you disagree with V = W / Q, then
show us your math. Back up your opinion with some figures.
1 Joule = 1 Watt-second (Power * time)
W = P * t
and P = V * I so
W = V * I * t
and Q = I * t and I = Q / t so
W = V * Q * t / t
W = V * Q
V = W / Q
That's V(Voltage in volts) =(equals) W(energy in joules) /(per) Q(unit of charge in Coulombs)

Yes, your equation is correct if you mean "W" for energy. You will excuse me, as my dictionary lists "W" as the international symbol for watts, as does this link. https://en.wikipedia.org/wiki/Watt
Volts = joules/coulomb is a density because it relates an amount of energy to charge in MKS units.
"Conversation of energy", I love it. That is the best I've heard in a long time. I think the Department of Energy are masters of "Conversation of Energy" how else could we get an Enron or Solyndra?

There are symbols for power and units for power. We use "P" for power in equations and other symbols for units of power, like W for watts, KW for kilowatts, HP for horsepower.
