When I was growing up, my brother and I had it drummed into our thick skulls, that the last one leaving a room had the duty of switching off the light. Saves energy, yadda yadda. Turns out it only made sense back then. It's a new day.
"Although the advice to turn off the lights was true for incandescent bulbs, which were incredibly inefficient (most of the energy released is heat, not light), the US has moved onto other types of bulbs, which are much more efficient.
You could have a dozen of LED bulbs going 24/7, and they would still consume less energy than what a typical fridge uses in a day.
Part of the argument against turning off the lights seems to be that switching modern bulbs on and off is detrimental to their lifespan regardless of the electric bill.
With LEDs, it really doesn’t matter at all. The technology that makes LEDs glow is completely different than that of traditional incandescent bulbs, and LEDs—even smart ones—aren’t physically stressed being turned on and off in the way that traditional bulbs are. As the DOE notes, turning an LED bulb on and off doesn’t affect its lifespan."
