This is true, but centralized power generation is a lot more efficient then creating the power individually at the point of consumption like ICE cars do today. I believe that an ICE motor is something like 30% fuel efficient, Electric something like 80-90% and a combined cycle blah blah gas turbine is more like 60-70%. So no, it won't be the full 14% but it won't be a few points either, probably safe to say 5-10% reduction.
