A dehumidifer uses more electricity per hour than an exhaust
fan, but the dehumidifer is going to run a lot less than a fan
set to run automatically by a humidistat which isn't aware of
the ambient humidity. When you consider the heated or air
conditioned air which is wasted by the exhaust fan, then the
dehumidifer is going to be much less expensive to operate.

A properly controlled exhaust fan can dehumidify with 100X
less energy than a dehumidifier.
