What do you think would happen to the energy bill at your school if all of the light bulbs were changed from incandescent to fluorescent bulbs.

The energy bill of school will decrease

Explanation:

The energy efficiency of Fluorescent bulbs are much more  than the traditional incandescent bulbs. An incandescent bulb heats a metallic filament while a fluorescent bulb excites a gas for producing glow. The amount of electricity consumed to heat the metallic filament is much higher than the electricity required to excite a gas with in the fluorescent bulb. Thus, on replacing incandescent bulbs with fluorescent bulbs , electricity consumption will reduce and hence the electricity bill of school will also reduce.
