I know fluorescent lighting is more energy efficient but how much energy is it saving?

Question by pink.love: I know fluorescent lighting is more energy efficient but how much energy is it saving?
What if all the fluorescent lights in a classroom were turned off, about how much money or energy would that actually save?

Best answer:

Answer by Jerry LeeIt will depend on the size of the classroom, and how well lit it is. It will require more lighting if it has dark paint or dark floors, or faces north, or they have classes at night, or there are no windows at all.

I estimate 1,000-2,000 Watts.
