A CFL uses 65% less energy and can reduce your power bill as well.
A longer answer
Since major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.
In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.
For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.
CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.
Another opinion
There are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.
But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.

Did you hear about the monster who ate light bulbs because he thought they have less calories than regular bulbs?
A light snack!
Are energy saving light bulbs brighter than regular light bulbs?
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.
What are some innovations light bulbs undergone since its original invention?
Light bulbs now have a larger wattage capacity and can be operated on higher voltages than what the original light bulbs started out at.
What are the pros and cons of a cfls light bulb?
Compact fluorescent light bulbs are cooler, use less electricity, and last a great deal longer than incandescents. However, they are more expensive than incandescent light bulbs and do contain trace amounts of mercury. They also have a slight delay before turning on.
What is difference between regular household light bulbs and led bulbs?
LED light bulbs definitely are more energy efficient than regularly normal light bulbs. Depending on the usage, LED lights can also last maybe twice or three times as much as regular bulbs. LED ones are better.

Why are energy saving light bulbs better than normal light bulbs?
LED lights are better than bulbs because they are more energy efficient, and environment friendly. You can definitely get a lot of savings with LED light bulbs.
How are xenon bulbs different from normal light bulbs?
Xenon bulbs are much brighter than regular light bulbs. They are more expensive that normal light bulbs. this is partly because of the cost of xenon gas, but also because of the heat generated by the bulb that requires them to be housed in quartz instead of glass.
What advantages do LEDS have over light bulbs?
LEDs are definitely better than the ordinary light bulbs because they're more energy efficient, and you'll be able to get a lot of savings since you don't need to change your bulbs every now and then.
What are some common uses of LED bulbs?
LED bulbs are commonly used in lighting fixtures and even in some TV's and flashlights. They use less energey than regular light bulbs.
Are Low energy light bulbs more expensive than conventional light bulbs?
no
Why are LED bulbs considered to be better at saving energy than compact fluorescent ones?
LED bulbs, or Light Emitting Diode bulbs are far more efficient at turning energy into light than fluorescent bulbs. They are the most energy efficient bulbs available today and last much longer than any other bulbs. Although very expensive, the price is expected to come down over time.
What are the benefits of using LED lamps?
Lamps using LED bulbs are more energy efficient than lamps that use traditional light bulbs. LED bulbs last over 25 times longer than regular light bulbs. Though they may cost more at the outset, the cost of usage of LED lamps is much less over time.
How efficient are commercial light bulbs compared to industrial light bulbs?
Industrial light bulbs typically have larger wattage than commercial light bulbs. This is because commercial light bulbs are more commonly used in public as opposed to private homes.
Do heat lamp bulbs use less than regular bulbs?
No, they use more electricity.
