Speedy, I'll let the Electrical Engeneers chime in here, but I do not argee with your math.

While you are correct about the "internal resistance" being half between the 2000kv and the 1000kv, that is not a direst equation to what you get in watts lost as heat. I will not get into thermo dynamics, but here is an example, the entire car industry, all around the world, switched their electrical system from 6volts to 12 because it made the components last longer and not heat up as much. Amp draw is what creates heat in a circuit, not voltage or even watts. A 120,000volt power line is not hot without a load. Less amps is less loss, that is a fact.
