This is bull****.
Sez you.
Turning on and off an incadescent light
does not use more energy
I never said it did. I said it "was usually more expensive than leaving
it on." There IS a difference. Figure it out, if possible.
I think you must be referring to shortening the life of an inccandescent
bulb by more frequent on-off cyscles and factoring the cost of bulb
replacement into the picture.
I'll agree that was probably true back when electricity was relatively
much cheaper than it is now, but I suspect what you learned back then
might not be true in today's world.
