Save more energy by using an energy saving flourescent bulb

I want to save more on energy whenever I use some of my appliances. I always put on the light every night in my room because I cant sleep when the light is off. I think of saving more on my electricity consumption that's why I change my florescent bulb to a lesser wattage. My previous florescent bulb watts was 32 while the present bulb is an energy saving bulb that has a 9 watts but has a greater output.
