CFLs are more expensive in the short term, and some people suffer adverse physical reactions to them.
The power consumption is lower on CFL lamps. Result, you save money operating them.
All track lighting models can use CFL bulbs. The important thing is that you get the correct CFL bulb as you must get the CFL bulbs that are designed for base up use like you find in track lights, pendant lights and recessed lighting. If the track lights are dimmable you also want to be sure to get a dimmable CFL bulb.

Look at the base. The power rating will be printed there.
No, it is not recommended to use a 100 watt CFL in a fixture that specifies a maximum of 25 incandescent watts. CFL bulbs have different wattage equivalencies compared to incandescent bulbs, so you should use a CFL bulb that is equivalent to or lower than the specified incandescent wattage for the fixture. Using a higher wattage CFL bulb can cause overheating and potentially pose a fire hazard.
no because it would blow up because the socket would draw 13 watt not 9 watt
In most cases a cfl bulb can be replaced with an incandescent bulb as long as the base matches. for an example: if a cfl bulb has a GU24 base an incandescent bulb will not work! Also, ensure the wattage of the bulb does not exceed manufacturers rating.
it look's like a mini light bulb and you usally use them in an electric circuit
A single bulb is better if you can get it, it's simpler to use, but 23 watt bulbs are easier to find. Five 23 w bulbs totals 115 watts so they would be a little brighter.
CFL bulbs use 75 percent less energy than incandescent bulbs, and lighting your home is about 20 percent of your energy use. If every home in America replaced just one standard bulb with a CFL, it would reduce greenhouse gas emissions equal to that of about 800,000 cars.
Fluorescent don't like the cold, they are slow to come on. I think they have come up with some for outdoor use but a refrigerator bulb is so small I don't think I would bother. Additionally, the lifetime of a CFL bulb is diminished each time the bulb is turned on, much more so than an incandescent bulb, and this may be a reason to avoid CFLs where the refrigerator door is opened frequently turning on the light each time.
um, electricity?
