Do you know how much fuel does AC buses burn compare to non A/C buses?<br />
Just think about your home<br />
if you turn the AC on 24 hours a day, 7 day a week,<br />
how much will the electricity bill be?<br />

Practically zero, because the dynamos of the internal combustion engines only drags energy when it is turning but does not burns fuel as a separate entity
Added with fuel savings from modern engines, it is very likely that modern a/c buses burn roughly the same amount (or even less) fuel than their older non a/c counterparts.

Then how come gas mileage is worst off with AC turn on?
This hold true from my own little car to our buses
Theoretically, my little car should have 32 miles per gallon in city, but I have never seen this happen
no matter how hard I try, turn off AC, easy accelration, less braking, nothing works
I have no idea how the car manufactuer figured out i can get 32 miles per gallon in city.
The point is: theoretically, the new technology may save gas; but practically, I have doubts
Thank you!~ and thats what i am talking about!
the engine may have been made to be fuel efficient with AC
but is that the way it works out?
Theoretically, yes! Practically, nah-ah~ I don't think so!
