i'm a little puzzled about the whole alternator kill idea. how much energy are we really saving?

I might be wrong but I can't agree with that right now here is why! Even though some energy will go to waste heat,the end result is reduced torque required to turn the alternator and your battery still gets charged given enough time to replenish used amp hours. Instead of it going to full output trying to recharge instantly. Not a fair comparison but people fine tune windmills this way when needed if the alternator is "too powerful" for the rotor blades/wind conditions and not letting the prop blades get up to a more efficient rpm. They add "line resistance" (longer cables) to allow lower wind speed operation. I know there are totally different factors involved with the propellers but I'm talking about the same electrical principal.
Not trying to argue here,we are just talking
Apologies to the OP if we're off topic!
