Does Turning the Air Conditioning Off When You’re Not Home Actually Save Energy?

PERSONALLY... I RUN MINE ALL NIGHT. (I CAN'T STAND TRYIN' TO SLEEP IN THE HEAT) PLUS, THERE'S NOT THE BIG RISK OF SURGES KNOCKIN' THE POWER OUT... THAT USUALLY HAPPENS IN THE AM & EARLY EVENING. (FOLKS GETTIN' UP FOR WORK & COMIN' HOME FROM WORK.)  I'VE NEVER LOST POWER FROM SURGES AT NIGHT, BUT... I HAVE LOST POWER DURING THE PEAK TIMES OF THE DAY, WHEN I DON'T HAVE MY AC RUNNING, BECAUSE I'VE LET IT RUN ALL NIGHT LONG FROM 10 -  13 HOURS, DEPENDING ON WHAT THE TEMPERATURE IS IN HERE..  SO FAR SO GOOD.  LOL

I'VE GOT 6" WALLS & CATHEDRAL CEILINGS WITH CEILING FANS.

THE ARTICLE MAKES A LOT OF SENSE, TO ME.
