The amount of mercury in CFL's glass tubing is extremely small, about 1/100 the amount in a common household thermometer, or roughly about 4mg. However, mercury is considered to be hazardous and polluting, therefore proper disposal just like other household hazardous waste products such as paint, batteries and non-digital thermostats is required. The concern lies in the concentrations of mercury accumulating in our landfills over time. Mercury is released in the environment when products like CFLs that contain mercury break. Exposure to mercury, a toxic metal can effect the brain, spinal cord, kindeys and liver.
So, if a CFL breaks:
DO NOT INHALE THE VAPOR!
DO NOT USE A VACUUM FOR CLEAN UP!
SWEEP THE PIECES OF THE BROKEN GLASS WITH A BRUSH OR BROOM - DO NOT USE HANDS!
CLEANUP GLASS WITH A WET RAG TOWEL AND PLACE TOWEL, ALONG WITH PIECES IN A SEALED PLASTIC BAG!
For more information you may visit www.Earth911.org , or call
1-800-CLEAN-UP to locate the nearest residential mercury recycling facility.

How energy efficient are Compact Fluorescent bulbs?
Switching from incandescent light bulbs to compact fluorescent light bulbs is an efficient way to save energy. Compact Fluorescent light bulbs use up to 75% less energy than regular incandescent light bulbs. They provide the same amount of light and last 10 times as long. And because they generate 70% less heat than regular light bulbs they can cut the amount of energy and costs used for home cooling. (http://www.energystar.gov/index.cfm?c=cfls.pr_cfls)
Compact Fluorescent bulbs save so much energy that if at least half of Americans would switch over to fluorescent, energy saving light bulbs, it would end the release of billions of pounds of carbon dioxide emissions. If homeowners changed at least five of their frequently used lights, each home would save over $60 a year in energy costs. All together that would save Americans over $6.5 billion in energy costs. That would also prevent the release of greenhouse gases equivalent to as much as the emissions of eight million cars. (http://www.need.org/needpdf/ChangeALightTG.pdf)
Switching to fluorescent bulbs is a simple and easy way to save energy and help the environment.

Question: How do compact fluorescent Light Bulbs generate light? How do incandescent light bulbs generate light?
Answer:
Answer:
Compact fluorescent light bulbs
Compact fluorescent light bulbs are made of two parts, the tube in which is filled with gas and the ballast. The glass tube is filled with small amounts of mercury. The glass is coated on the interior with a layer of white phosphor. The electric current or the magnetic current flows through the ballast and then through the gas and then omits a white light.

http://www.lightbulbdepot.com/Common/helpdocs/compactFluorescentBulbBase.jpg
Incandescent light bulbs
“An electrical current passes through a thin filament, heating it and causing it to become excited, releasing thermally equilibrated photons in the process. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation.”

If I drop a bulb and it breaks, is there any harm from mercury contamination? And how do I dispose of the broken pieces of the bulb?

Compact fluorescent bulbs contain small amounts of mercury. The mercury poses no threat while in the bulb, but if you break one of these bulbs, be careful and do not inhale the mercury, Using a wet rag, clean it up immediately and put the rag as well as the broken pieces into a plastic bag.
Although household CFL bulbs can be disposed of within regular trash pickups, they are categorized as household hazardous waste. As long as the waste is sent to a modern landfill, the hazard to the environment is limited. However, CFL’s should not be sent to an incinerator. The mercury would be dispersed into the atmosphere if the bulb would be burned.
It is suggested that you save old CFLs until your town or county holds a hazardous waste collection day. The collected bulbs would then be sent to facilities capable of treating, recovering or recycling them. If you are interested in obtaining any additional information on the disposal or recycling of CFLs contact your local municipality.

What is the energy efficiency of CFL’s compared with incandescent light bulbs?
The energy efficiency of CFL’s offer many benefits over the old-style incandescent lighting. The twister lights use 75% less energy and money with incandescent lightening. The more modern up to date have a higher quality of light and the color is better. They also come in different temperatures. Since 90% of the energy is used to produce light little of the heat is used and reduces cooling costs. Incandescent light bulbs turn 90% of the energy used into heat and only 10% of the energy into light. Fluorsescent bulbs produce the light up to 8 times longer than standard incandescent bulbs. The twister bulbs contain mercury which is a material that should not be let out to the air of the environment. It came to my attention that the original lights that we use are being used more for electricity than for the actual light. Even when turned off they are using a lot of energy. Why not save money and purchase the CFL lights that are safer and cheaper for your home.

What are the cost savings in switching to CFL’s?
A compact fluorescent light uses at least 2/3 less energy than the standard incandescent light bulb and last ten times longer providing the same amount of light. Each compact fluorescent light bulb would save you at least $30 for each bulb compared to the lifetime of an incandescent light bulb.The CFL’s generate 70% less heat than an ordinary bulb which would allow you to safely touch the bulb and not get burned and during the summer months the heat output would be less, which would eliminate the need for your air conditioner to run more to cool your home from the heat of a regular incandescent light bulb.

Global Warming Response Act
The Global Warming Response Act
A3301/S2114, sponsored by Assemblywoman Linda Stender (D-22) and Senator Barbara Buono (D-18), requires mandatory limits on New Jersey’s global warming emissions from all sources. It is modeled off the California Global Warming Solutions Act, AB32 (Nunez/Pavley).
Specifically, the act requires the New Jersey Department of Environmental Protection (NJDEP) to establish a greenhouse gas reduction program to reduce the global warming emissions, primarily carbon dioxide, produced in New Jersey to below 1990 levels (roughly 20 percent below current levels) by 2020.
Within a year of the act’s passage, the NJDEP is required to establish relevant global warming emissions inventories, prioritize sources for global warming emissions reductions and adopt rules and regulations to achieve reductions below 1990 levels by 2020.
On or before January 2008, the act requires the NJDEP to establish a global warming emissions monitoring and reduction program and establish a series of interim emissions reduction requirements targeting specific sources to achieve the reductions. The first global warming reduction requirement must be met by January 1, 2012, and the bill lays out that further reductions be phased in, year-by-year, from 2012 through 2020.
The act requires the NJDEP to identify, monitor and enforce projected and annual emissions from all sources, including emissions from electricity sources located outside of the state that import electricity for use in New Jersey, and to monitor emissions from all sources. According to the most recent data available, 52 percent of New Jersey’s global warming emissions comes from transportation, 16 percent is from in-state electricity generation, 13 percent is from direct use of fossil fuels in homes, 11 percent is from direct use of fossil fuels in industry and 8 percent is from direct use of fossil fuels in commercial business. New Jersey also produces emissions through consumption of electricity generated in other states.
The act requires that on or before January 1, 2009 and annually thereafter, the NJDEP must report back to the Governor and the legislature on current levels of global warming emissions and progress toward meeting the reduction requirements. By January 1, 2015, the NJDEP must evaluate the attainment or maintenance of the 2020 reduction requirement and adopt further regulations to attain or maintain the 2020 requirement or require further reductions beyond the requirement. If further reductions are required, the NJDEP must establish an additional global warming emissions reduction requirement by 2030 and a schedule to attain that level of reduction.
The Global Warming Response Act is ground-breaking legislation. If passed, New Jersey will be one of the first states to adopt mandatory limits on global warming emissions from all sources.
Environment New Jersey is urging all members of the New Jersey Assembly and Senate to co-sponsor A3301/S2114 without delay.
(www.environmentnewjersey.org)
This act came within a week of Governor John Corzine’s executive order on global warming. “Governor Corzine rose to the challenge today by establishing a firm, far-reaching, science-based commitment to reduce New Jersey’s global warming emissions.” (http://www.environmentnewjersey.org/news-releases/global-warming/global-warming-news/governor-corzine-issues-executive-order-on-global-warming) This shows that specific states are more willing to take action against global warming than our American government itself. These states include California, New Mexico, Arizona, Washington, Illinois, and North Carolina.
In my opinion the only word that comes to mind is “FINALLY’. It is about time that our government is taking action to save the earth for us and those that shall come after us. New Jersey is now a leader in the reduction of greenhouse gases, and if we were to rank the top “reducers”, New Jersey word come in at 32nd in the world

Dimming
The compact fluorescent light bulb is a newly advanced light that is energy efficient. Everyone should be earth friendly and switch from incandescent light bulbs to compact fluorescent. The dimming aspect of the fluorescent bulb is it uses fewer watts and produces a brighter light than a incandescent bulb. The only negative effect is upon turning the bulb on, it is dim for a short time period, until the gases inside the bulb build up. Compact fluorescent light bulbs are used for lights that are intended to be on for long periods of time.

How much money does the Compact Fluorescent Light Bulb compare to the Incandescent Light Bulb?
Christine Clossey
According to Wikpeda, they are saying that the Compact Fluorescent Light Bulb can last about 8,000 hours, compared to the incandescent light bulb which last about 500 to 2,000 hours. This means that you’ll be saving a great deal of money by using the Compact Fluorescent Light Bulb. From my personal experience, my family got the CFL bulbs and it lasted it a couple of years, meaning that we saved lots of money not buying the regular bulbs. This chart that I got off Wikipedia this explains how you would be saving money:

incandescent= (75W)X(8,000) X ($0.08/1000w X hr)= $48.00
According to this chart say you had a normal incandescent light bulb and compare it to the CFL. The normal bulb uses an average of 75 Watts as to the CFL which uses 20 W. Say both of these light bulbs last 8,000 hours. They say that cost of electricity in America is about $0.08 per kilo Watts per hour. As you can you tell by the charts this saves you a great deal of money. According to the Energy Star website “Save $30 or more in energy costs over each bulb’s lifetime”. So not only does this light save a great deal of money, it also helps save our earth, our true home.

How much money saved on Fluorscent light bulbs?
How much money are you saving by switching to Fluorescent lightbulbs?
Generally the Florescent lightbulbs are a bit more expensive than standard incandescent bulbs. I looked on walmart.com and found that a 6 pk of 20 watt fluorescent bulbs come to $15.16. Where as you can find incandescent light bulbs at your local supermarket where they can go for about 5 dollars for a 4 pk. . (2)(3)foIt would cost about $2.55 per each CFL bulb and $1.26 for each incadescent bulb.According to Wikipedia "CFLs are typically guaranteed for 8,000 hours. (Incandescent bulbs typically last 500 to 2000 hours, depending on exposure to voltage spikes and mechanical shock.)" (1)
"The CFL, therefore, will save $36.00 in electricity (compared to the incandescent bulb) during its rated life. Some American discount stores sell packages of CFLs for about $2.75 per CFL and incandescent bulbs for about $0.50 each, a $2.25 difference. The estimated payback period for buying the CFL instead of the incandescent bulb is, therefore, 500 hours, which is 100 days at 5 hours per evening. Two additional advantages of the CFL are that the majority of these bulbs never get beyond touch-warm( meaning warm enough that it wont burn your hand if you touch it), making them significantly safer for children and the elderly, and providing a reduced risk of fire in homes and offices."
so in my opinion, the fluorescent lightbulbs may cost a bit more , but they will save you good deal of money on electric (1)

What's the difference between a compact fluorescent light bulb and a fluorescent bulb?
"The primary differences are in size, shape and energy usage; compact fluorescent bulbs are made in special shapes (which require special technologies) to fit in standard household light sockets, like table lamps and ceiling fixtures. In addition, most compact fluorescent lamps have an "integral" ballast that is built into the light bulb, whereas most fluorescent tubes require a separate ballast independent of the bulb. Both types offer energy-efficient light. " 1
"A ballast is used to stabilize the current flow in lamps. Ballasts vary greatly in complexity. They can be as simple as a series resistor as commonly used with small neon lamps. For higher-power installations, too much energy would be wasted in a resistive ballast, so alternatives are used that depend upon the reactance of inductors, capacitors, or both. Finally, ballasts can be as complex as the computerized, remote-controlled electronic ballasts used with fluorescent lamps."2

An Easy Way To Save Money
How many lbs of CO2 are saved by converting to a compact fluorescent light bulb?
Switching to a compact fluorescent light bulb is an easy way to reduce your energy consumption, while lowering your energy bill. Sources state that, "By switching one incandescent light bulb to a compact fluorescent light bulb can save 150 lbs of carbon dioxide emission a year" (www.wikihow.com/Reduce-Your-Greenhouse-Gas-Emissions). This is because a compact fluorescent light bulb converts more of its consumed energy to visible light than an incandescent light bulb does. An incandescent light bulb converts 10% of its energy to visible light and 90% of it gets converted to heat, while a compact fluorescent light bulb converts 90% of its energy to visible light and 10% of its energy is converted to heat (www.wikihow.com/Reduce-Your-Greenhouse-Gas-Emissions). In California one newspaper, The Tracy Press, wrote an article that stated: "Replacing a 75-watt incandescent light bulb with a 20-watt compact fluorescent light bulb would prevent 1,300 lbs of carbon dioxide from being pumped into the atmosphere by electric plants a year" (www.tracypress.com/content/views/7533/2/). So change one light bulb to a compact fluorescent one, and save some money and reduce the carbon dioxide emission.

Cost?
Cost of Light Bulbs
Based on the research I conducted I found that the new light bulbs by General Electric are fairly cheap. However, you have to find the right store to buy them from, because if you go to Home Depot to buy them, they only sell them in single packs that cost as much as $7.99 per bulb. When I looked at the Wal-Mart website I was able to find much more reasonable prices including what I consider the deal of the century to be. The deal was a 12-pack of 60 watt bulbs for just $19.76; it came out to be just $1.65 each. Some other deals were 100 watt and 75 watt in packs of 6 for just $3.96 each. Eric Auerbach

What is the Light Quality of Compact Fluorescent Lightbulbs?
- A phosphor, a substance that exhibits sustained glowing after exposure to light or energised particles such as electrons, emits light in a narrow frequency range, unlike an incandescent filament, which emits the full spectrum.
- "Fluorescent lamps are usually operated on ac circuits with a frequency of 60 Hz(A unit of frequency equal to one cycle per second). However, higher frequencies permit higher-efficiancy lamp operation along with ballasts of lower power dissipation per watt. Consequently, systems have been developed for the operation of fluorescent lamps at frequencies from 360 to 50,000 Hz. The most important high-frequency ballasts operate the lamps in the 25-kHz range, are lighter in weight, can have flicker-free light output, and will continue to be more cost-effective as the cost of electricity increases." http://www.answers.com/topic/hertz
- CFL's take about 30 seconds or more to reach full luminosity. Incandescent lightbulbs only take .1 seconds.
- CFL's do not fail suddenly like incandescent lightbulbs. Instead they take longer to achieve full luminosity, there are random periods of reduced brightness, and there is an appearance of growing black spots of the glass tubing inside.
- If CFL's are used outdoors in very cold weather, they can take several minutes to achieve full luminosity or may not turn on at all.
