I am saying that even if you do turn the aircon off when
you arent in the house, the only effect of daylight saving
is the outside temperature seen in just the one hour at
the start of the time you turn the aircon on for when you
turn it on when you return to the house after work or school.
Tho I spose that if you normally do turn the aircon off
at night, and most people don't, you can certainly
say that there is an extra hour when the aircon is on
if they don't have it on the morning before they leave
the house. My neighbours do mostly have their aircon
on 24/7 in the hottest weather and some leave it on
when they are out of the house too, but that's mostly
with the much cheaper to run evaporative cooling.
Still happens with those with proper refrigerative cooling
tho, particularly when the house is well insulated.
> Are you saying a lot of people leave the air-con on all day?
Yes they do.
> That is just asking for a house fire.
Nope, you don't get house fires with aircons.
And heaps leave their house heating on when they are out
of the house, just so that its not frigid when they get home.
And in much colder northern climates hordes do leave
some heating on right thru the winter even when the
house isnt occupied, to stop the water pipes freezing.

Nope, its because that sort of trial is such a disruption to normal life.

That's certainly not the case in the biggest places like Australia and the
US.
It does make sense in the smaller places like Britain which just have one
timezone.

There is no shearing with daylight saving.
Its much more about a difficult compromise between
those that want it and those that hate it.
