I think you meant "use less energy" rather than "saves less energy"...
Incandescent light bulbs generate light by heating a filament until it glows brightly. A great deal of energy is lost as heat and only a little energy is converted to visible light.
Fluorescent light bulbs (whether "compact" or not) generate light by exciting the atoms in the phosphor coating on the inside of the bulb. This is more efficient, as there is less heat generated, so less electricity is needed to produce the same amount of light.
LED lights are even more efficient than fluorescent, but they are still rather expensive for general lighting.

∙ 14y agoAn incandescent light bulb produces a lot of waste heat. Fluorescent lights do not get nearly as hot.

∙ 13y agoA florescent light bulb saves energy because it does not take alot of energy to power it. It circulates the light so it is just as powerful.

Why have energy efficient light bulb?
I think it's the law in the UK and they save energy and are therefore more eco-friendly but they are also kinda annoying because they are quite dull at first.
How much energy does an energy saving light bulb save?
I'm pretty sure a CFL (compact florescent lightbulb) uses 1/3 the amount of energy of a regular lightbulb and lasts up to 10 times longer!
What are facts on the light bulb?
1 The light bulb was invented in 1879 by Thomas Alva Edison. 2 When you turn on a light bulb only 10 per cent of the electricity used is turned into light, the other 90 per cent is wasted as heat. 3 In the UK we waste £140 million a year by leaving our lights switched on unnecessarily - this causes 900,000 tonnes of CO2 emissions, enough to fill 180,000 hot air balloons! 4 Low energy light bulbs last on average up to 12 times longer than traditional fluorescent bulbs. 5 Each low energy light bulb you install in your home could save you as much as £9 per year in energy costs, or £100 over the bulb's lifetime 6If every UK household installed just three compact fluorescent light bulbs in place of traditional bulbs, enough energy would be saved in a year to supply all street lighting in the UK 7 UK households use £1.9 billion worth of electricity every year on lighting 8 Energy efficient bulbs last up to 12 times longer than their inefficient counterparts 9 A heavy coat of dust can block up to half of the light 10 If everyone installed one energy-saving light bulb the carbon dioxide emissions saved would fill the Royal Albert Hall nearly 2000 times.

How to Easily Remove a Light Bulb?
How to Remove a Broken Light Bulb EasilyFor decades, people have used potatoes to safely and easily remove a broken light bulb. Other methods can increase the risk of sustaining an injury, and using a potato is easy and cost efficient. This video demonstrates how simple it is to remove a light bulb with a potato.3 Simple StepsFirst, take your potato and cut it in half along the short width. Do not cut along the length because you will need enough potato to press down into the bulb socket.Cut side down, press the potato down with a slight twisting motion into the socket, making sure you reach the bottom.Twist the potato with the now-attached light bulb out of the socket like you would a normal light bulb.Now, if you followed these steps, you have safely removed your light bulb and can insert a fresh compact fluorescent light bulb into your light fixture. Using a compact fluorescent light bulb can save you up to 75% electric as opposed to a traditional incandescent bulb, and lasts much longer. Be sure to use a lamp shade to minimize the occurrence of broken light bulbs. Also keep light bulbs away from water. A hot bulb will explode on contact with water. If a light bulb ever does explode, remember never to touch it with your bare hands.
Which of these is not a smart strategy to save energy and costs in new and existing homes?
installing incandescent light bulbs
What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as heat
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
How are modern light bulbs different from the old light bulb?
I think they save energy and are folersent but what do i know
Are cfls good?
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.
What percentage of energy does an energy saving bulb save compared to an ordinary bulb?
It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.
How does the energy saving light bulb save energy?
It uses less fuel (electricity) and that elecriticy is converted more into infare rays (light)and less thermal energy (heat).
What color should a room be painted to save energy?
Try light color that let in light so that your bulb wont have to produce as much energy to light up a room.
Which light bulb will help me save money on my electic bill?
Yes, I do have LED lights at my home. LED lights actually helps you to low down your electricity bill. LEDs significantly reduce energy consumption than the conventional light bulbs, and thus help save money by lowering electricity bills.
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
If you leave one bulb in a triple light fixture will you save energy?
As opposed to having 3 bulbs in it, yes.
Does a energy saving light bulb save energy because it is curled?
nope. It's curled to make it compact enough to fit into ordinary lamps.
Do halogen bulbs save energy and money?
Halogen light bulbs are more efficient on energy and last twice as long as a regular light bulb thus saving you money. After researching several websites on energy it is stated that a regular light bulb costs $9.49 for 1460 hours of use whereas a halogen light for the same amount of hours costs $8.76.
