So a generator is magnets and copper coil yeah? They make electricity and electricity is moving electrons. Power generators and electric stations are kilometres away. Do the copper coils get their electrons back?
Won’t the copper coil run out of electrons. How the electrons come back (if they do)?

So you have two kinds of electricity: Direct Current and Alternating Current.
With Direct Current, yes, the electrons leave the power plant, travels through the wires to your house and then back to the power plant. Assuming you give it enough time, that is, as the electrons travel a lot slower than you’d expect, something like a millimeter a second in the wires you’ve got in your house.
With Alternating Current, the direction of the currency switches every 1/60th of a second in North America (every 1/50th of a second in Europe). So the electrons don’t really have the time to get anywhere, just back and forth.
