When electric current is transmitted though time and space using a wire it is wrong to believe the electrons from the source generator are actually buzzing at or near the speed of light along the outside of the conducting wire . What is really happening is the generator is producing an electrical disturbance with what I have been calling dark photons which are code moving form electron to electron along the conducting wire. As code these dark or embedded photons that are not radiating out into space but going from atom to atom via the electrons send a message from one to the next which are conveyed to the point of energy use and then in a transformed state back to the source as a different code. in Transit there is radiation because of resistance. This resistance is a sort of subatomic collision that rather than transmitting energy finds it in the state of underlying momentum and that leads to photon radiation or "light photons' coming off. Direct current is more successful at causing this radiation effect where as alternating currency has less loss of "power" over the transmission lines at a distance. The reason why supports the pure code thesis for photons because it very well can be that alternating current rolls the electrons effectively canceling out those collisions thus preventing more radiation from occurring. It helps to visualize one code neutralizing the other with alternating current where the two opposite code instructions neutralize what would be a collision force in direct current. The pure code photonic thesis solves the mystery of why alternating current has the advantages over long distances that it does over direct current. Pure code and a cancelation process explains it.
It seems difficult to believe that underlying momentum has anything to do with energy originating from an electric generator that is until you start looking and seeing the actual physical means of producing that electric current. Start with your hydro electric dam with it's very large generators that rotate very fast because water causes huge turbines to spin as it falls over the dam into a spillway that rotates the turbines. The turbine causes magnets and wound up copper wire to spin with some resistance to the force of the magnetic field with in. The power of the spinning is equivalent to the work being done and close to that of the value of the electric being generated for transmission. A generator is not easy work to spin. Its resistance to spinning has a lot to do with the transmission of energy. If you have a hand held crank generator you don't just spin the wheel effortlessly but have to experience its resisting your spinning it. Does that send code down the wire or a stream of electrons? as stated above electrons would rather stay closer to their home atoms than stream down the exterior of a conducting wire. how is that wheel spinning and does it have any relationship to the net motion of the earth in the solar system/galaxy/ universe. You have to think frames of reference to get how it happens. We don't feel like we are moving with the earth at over 800,000 meters per second until we crash into something say possibly a cosmic ray coming from the opposite direction at a rate of velocity or greater. We don't think of the earth as a sort of bullet moving fast enough to vaporize something of equivalent size that it crashes into at that rate of velocity. Sub atomic particles experience that sort of thing directly their frames of reference are not the same as ours. What appears to us as stasis seems to them as a full collision. The velocity of the earth against the backdrop of the rest of the universe for electrons and other subatomic parts leave them at a potential energy level like water standing in a reservoir above a dam. That water above the dam relates to the generator with its turbines waiting for the water to fall and move the turbine. Frame of reference disparity can account for whats not easily apparent.
