Fluorescent lights are more energy efficient because they use less energy to produce the same amount of light than an incandescent light bulb.
In the case of the fluorescent light bulb, light is produced by exciting atoms (the mercury gas), which then gives off UV rays, which strikes the glass of the tube, which is covered in a sort-of glow in the dark paint. The UV rays make the "paint" glow, which is how they light-up.
The incandescent light bulbs force electrons through tungsten filament, which resists the flow of electrons. This resistance causes immense heat, and makes the filament literally glow white hot.
Fluorescent light bulbs do not get "hot" like incandescent light bulbs, and that is the main reason they are more efficient. They better engineered to produce light, not the heat that comes with incandescent lights.
Hello,
I use mainly fluorescend bulbs in my place and they do save a lot of energy. I have no idea how. Here is some useful info I found online:

They save energy by not being turned on. if never manufactured, the savings is monumental, but not realized.
I guess we look at candlepower or lumens instead of just Watts. Electrically excited clouds of ionizing halides gives more lumens per watt than a white hot tungsten slivery filament.
More energy goes into making light, less energy into making heat.
How does using fluorescent light bulbs instead of incandescent bulbs help conserve energy?
