There are different ways to produce energy, but many of them involve burning some substance - for example, petroleum - that produces CO2.

How do you think energy transfers would be different in a lamp using a more efficient light bulb?
It would be more different since it will take up more power than the less efficient light bulb. Instead of using all the solar power it will probably need the forces of 2 energies to light the bulb.
Which of the areas of technology best classifies the light bulb?
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Which bulbs consume less energy?
Common indoors type light bulbs, from most efficient to least efficient: regular size tubular fluorescent lamps with electronic ballasts CFLs (compact florescent lamps) fluorescent lamps with reactive ballasts (old type of ballast) incandescent halogen lamps incandescent tungsten lamps
How is the new light bulbs energy renewed?
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.

Is a energy saving light bulb more efficient than a normal light bulb?
More efficient, yes - since it produces the same amount of light but uses less power to do so. HOWEVER - they need to be disposed of away from the 'normal' household rubbish - as they contain mercury - which is highly toxic !
What does an energy saving light bulb do?
It uses less energy to produce the same amount of illumination as a standard light bulb
How does a florecent light bulb save energy?
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.
What is Florescent?
flouescnet is a type of light bulb that uses less energy
What are energy efficient light bulbs?
A Low energy bulbs uses about 1/5 energy of a traditional bulb. ie. 20w (Low energy bulb) = 100w (standard filiment bulb) 80%+ traditional bulb s' energy is lost as heat. The 20% figure shown above only relates to the low energy bulb during its normal usage. The question was about the overall ecological balance, which includes ecological burden through manufacture, distribution and disposal (or recycling). Low energy light bulbs contain heavy metals, electronics and toxic materials, and are manufactured (and recycled) using much more complicated and, presumably, more ecologically damaging processes compared to those involved in traditional tungsten filaments. The question is still open thus.
How much does energy efficent light bulbs cost per hour?
There is actually no energy efficient light bulbs in a way to interpret in physical determination. Energy efficient means less Watts required per hour compared to non energy efficient.
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 type of energy does a light bulb give off?
It makes thermal energy (the heat), radiant energy (what we see), which is in essence more or less the same manifestation.
Can energy saving light bulb charge a phone?
No. An energy saving light bulb is just a light bulb, and can't charge anything. The reason it's called an "energy saving" device is that it can give you the same amount of light while using less electrical energy than older bulbs used.

The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
What are the differences between a energy efficient light bulb and a regular light bulb?
Energy saving bulbs reduce electrical consumption by about 75%, reduce bulb changes by x10 to x50 times. The savings in electricity and their endurance more that compensates for the higher purchase price.
