Why do people buy low energy bulbs?
People buy these bulbs because it saves more electricity. However these bulbs may only have a little efficiency meaning that most of the energy is converted to heat while the small percentage is converted to light.
If two bulbs in a series circuit are equally bright then they transfer energy at different rates?
Whether or not they're in series is an irrelevant detail. If the two bulbs are equally bright, it means that they're dissipating energy at the same rate. They can dissipate energy at the same or at different rates whether they're in series or parallel circuits. It only depends on the characteristics of the bulbs.
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.
Does marijuana grow with energy saving light bulbs?
The amount of energy used by a lightbulb does not affect a plants growth, only the brightness and spectrum of the light produced.
Why can light bulbs be called heat bulbs?
Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.
What is collective accommodation?
There is no collective noun for accommodation, there are only synonyms that are nouns, such as room, hotel, seating, etc.
How do light bulbs cause global warming?
In a incandescent light bulb almost 90% of the energy taken in is being wasted as heat. only 10% is being used as visible light. this means that alot of energy taken in from ex sun,vind and water are not being used as it should have been. Thats why the LED bulbs are so good because they dont give out as much wasted energy
How does fluorescent light bulbs help conserve energy?
It's because it need only 20% of the electrical power to produce as much light, therefore less energy is wasted.
Are there any table lamps out there that only take energy efficient light bulbs?
I have not ever seen a table lamp that only requires a energy effcient light bulb. Usually all lamps will accept any light bulb regardless or energy wattage or usuage.

Can I save energy using one light instead of four in my kitchen light or is it the same no matter what?
Yes. If your kitchen light has room for four light bulbs, then you will save energy if only one of them is on.
Saving Your Dad Money on Fathe's Day 2011?
For Fathers Day 2011, think about eschewing the typical gifts and giving your dad something more practical. Change out all of the light bulbs in his home with energy efficient bulbs. Because energy efficient light bulbs use much less power than incandescent light bulbs, a house full of them will drop utility bills dramatically. When choosing energy efficient bulbs for Fathers Day 2011, you will have three options. First, you can swap out the bulbs for fluorescent lights. Fluorescent lights are inexpensive, but you will more than likely have to change out all of the lamps and lighting fixtures since the bulbs are not compatible with lamps that take incandescent bulbs. Next, you can opt for the compact fluorescent lamp (CFL) bulb, which are fluorescent lights that are made to fit into traditional light bulb receptacles. Not only do these bulbs use much less energy than regular bulbs, but they will also last much longer, saving your father money in the long run. Finally, you can choose to buy light emitting diode (LED) bulbs, which are also energy efficient. Because these are new, they are more expensive on the front end, but will last longer than CFL bulbs as well as use less energy.
