Wired doorbells have a transformer which is always on and always using

These things add up...

I replaced/rewired my switch so the transformer is only on when the
doorbell button is pressed! Thus the transformer is off most of the time
now.

I installed a regular electrical box at my front door, ran 14 ga. romex
from this box to the doorbell transformer, then got a nice brass blank wall
plate, drilled a hole in this plate, then installed a 120V momentary push
switch in the plate. Then wired this to switch on the transformer when the
button is pressed. Then connected the two wires which were going to the old
button so the doorbell would ring as soon as it receives power from the
transformer.

My first thought when reading this was "ok...so we'd save a few
pennies a month". But I investigated and found a rather interesting
read related to your theory where the author actually tested the
doorbell transformer using a Kill-A-Watt:

Luckily my doorbell isn't lighted, so it's probably not worth my time
and effort to change.

yeah, the article stated 3 lousy watts for a *lighted* doorbell. I doubt
that an unlighted doorbell switch even draws a watt. It's a transformer
but it has *no* load on it at all except for the brief moment it's pushed.
Much ado about Nothing.

One watt for a year would be about a dollar a year. The payback
on all the OP's effort will take a Long time. g
