Is there a law in the US phasing out regular light ulbs in favor of CFL's?

Yes. Currently it becomes effective in 2014. However, stay tuned.
As more and more people become aware of it, there is a groundswell of disapproval beginning, and it MAY be the subject of a repeal.

What is an example of common technology that does not efficiently convert energy?
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.

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 are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
How can the disadvantages of cfls be minimized?
The benefits of using CFLs could be maximized because when we are using CFL’s we think it is all good but it has some bad toxins that are creating the energy to make the light and make it use less energy. We have to dispose the CFLs properly to reduce the spread of the toxins.
Can a energy light bulb be usedwith a regular dimmer switch?
Some CFLs (Compact Fluorescent Lightbulbs) can be used with a regular dimmer. CFLs that can be used with a dimmer will be marked as such on the packaging. They are a little bit more expensive than non-dimming CFLs. It may be helpful to ask an employee at the store if you are unable to find the bulb you need. I tried one dimmable CFL and thought it was terrible. The light color was unnatural, it was slow to get bright, and the lowest dim setting was not very low. In the end, I returned it to Home Depot with less than 5 minutes use on it. I talked with a lighting store owner about "good" green lighting solutions, and he said that the technology just isn't there yet. Currently, if you want good light while saving electricity and increasing bulb life, simply dim the regular incandescent bulbs you have now (according to him). Of course, setting a dimmer to 80% isn't going to be as energy efficient as using a CFL, but it will offer some savings. I would expect better solutions within the next five years. I do use CFLs in my patio lights, and in some other lights that I don't care much what they look like. But for my "real" lighting, I use regular incandescents with dimmers. Hope that helps. -- Eric
What can covert electrial energy to light energy?
Ordinary light bulbs, fluorescent tubes, CFLs, flashlight bulbs, LEDs, toaster elements, and laser diodes all do that.
What are the twisty light bulbs?
These are compact fluorescent lights (CFLs) that produce light but save energy while doing so. In fact, they actually produce more light than a standard light bulb but use less energy while doing so. What makes the CLF different is that the CLF is made from a gas-filled tube and a ballast, while the regular light bulb uses a filament. Hope this answers your question.
Why don't people always use energy saving lights?
The only widely-available replacement for the standard incandescent light bulb is the compact fluorescent light (CFL). While these bulb replacements (actually spiraled, gas-filled tubes) use much less electricity to operate, they cost much more to purchase and have other liabilities. People who don't always use energy-saving lights may simply have not gotten around to it yet, or they may have made a choice against them, balancing the positives and negatives. Here are some of the negatives related to compact fluorescents: * Initial cost of replacment CFLs is high, many times the cost of a light bulb. * Economic payoff may not come for a few years. * It's expensive to replace all the lights in a house at once. * Although these expensive CFLs are supposed to last much longer than light bulbs, they often don't. * Some CFLs are particular about which direction they're pointed; they don't last as long or put out as much light if pointed the wrong way. * Many CFLs don't immediately put out the full expected amount of light; they may take a few seconds--or longer, in cold areas--to warm up. * CFLs do not work well in very cold places. * Aesthetics: the look of a twisted coil is seen as less attractive than a glowing, lit globe. * The light put out by a CFL--generally the "cool white" color most fluorescent tubes produce--is dfferent from the red-yellow light people are used to in the home. (Although "blue-light" CFLs are becoming available.) * CFLs, as all fluorescents, flicker 60 times a second. Some people are uncomfortably sensitive to the flicker. * CFLs may also produce an irritating buzz or hum that some are disturbed by. * CFLs produce electromagnetic interference that can interfere with radio reception. * CFLs are not available as replacements for candelabra and other designer or specialty bulbs. * If a lamp or a light fixture cannot accommodate CFLs, a new fixture that does would have to be purchased and installed. * CFLs are not yet available as floodlights or spotlights. * The actual environmental impact of manufacturing a CFL is worse than for manufacturing a standard bulb; the CFL contains plastics, electronics, and mercury. * CFLs are generally not as weather-resistant as ordinary light bulbs. * A broken CFL (as with any fluorescent light) releases poisonous mercury. If broken over a carpet, there is no safe way a householder can clean up the chemical spill. It will likely be necessary to cut out a portion of the carpet. * There are tools available, using grippers or suction cups on long handles, for removing and replacing high-up light bulbs. Such tools will not work with most CFLs, and it is inadvisable in any case to grasp the tube itself and risk breakage. New designs of CFLs are coming out often; they may have now or soon solved some of the above issues. Lights that produce illumination through the use of LEDs (light-emitting diodes) are starting to be produced; they may be a superior and better-accepted solution.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
How are cfls made?

What are the benefits of CFL light bulbs and how can it be maximized?
the benefits of CFLs can be maximized by were you put them you should always put them in high usage areas vea the kitchen
