 If you were turning the alternator by hand, you would feel more and more
resistance--more effort required, i.e. more HP--to turn the alternator, at
the same speed, as the load increases.  Since the power output of an engine
is more-or-less fixed, there will be less HP at the driven wheels when you
have more electrical accessories running.
