The Dark Side Of CFLs

E-mail Print

Consider this - instead of saving the environment, CFLs are actually destroying it. CFLs should be thought of as toxic technology, when mercury contamination, ultraviolet radiation, and radio frequency radiation are factored in. From cradle to grave, CFLs pose a danger to people’s health and well being, as well as adding even more toxicity to the environment. In fact, CFLs do not reduce a person’s carbon footprint and may even increase it in some situations. To make matters even worse, CFLs emit harmful levels of electromagnetic radiation.

Starting in the year 2012, regular incandescent bulbs, the ones invented by Thomas Edison over 100 years ago, will be banned in Canada in the pursuit of reducing greenhouse gas (GHG) emissions. Yet, contrary to popular belief, switching from regular bulbs to CFLs could increase global energy consumption, not reduce it. If that alone does not shake consumer confidence, perhaps the facts that CFLs contain mercury and also emit electromagnetic radiation might give people a wake-up call up to the truth about CFLs.

On the other hand, since CFL producers are being handed a monopoly in the light bulb market by some federal government and are being cheered on by corporatist environmental groups, sales are not about to drop anytime soon.

It seems like the protectors of the environment have jumped ship. Health Canada is simply not doing its job as they ignore the devastating impact of having millions of CFLs in our environment. Why are they sitting by, and allowing the Canadian government to force its citizens to use them?

To make matters even worse, groups such as the Suzuki Foundation and Greenpeace, whom Canadians have come to rely on to protect them from environmental pollutants, have chosen to ignore the potential looming environmental and health risks, and blindly promote the use of CFLs.

Why have environmentalists and the government joined in an alliance with the electrical industry in promoting an undeniably dangerous product? Whose side are they on anyway?

Canadian Health and Safety officials seem to be asleep at the switch, oblivious of the hazards, and environmentalists appear to have sold out, as manufacturers and sellers of CFLs are laughing all the way to the bank.  With impunity “los tres amigos”, the manufacturers, the corporatist environmentalist backers and government, are leaving misled consumers to deal with the aftermath of a potential environmental catastrophe.

Meanwhile, the New Zealand government, citing concerns about CFLs lack of efficiency and safety, has lifted its ban on incandescent bulbs.  Hopefully other governments will see the wisdom in this decision and follow suit.

Corporatist Environmentalists

Corporatism is the dominant ideology in today’s western democracies. “While the corporatist society maintains a veneer of open criticism and democracy, it squelches opposition to dominant corporate interests by using propaganda and rhetoric to obscure facts and to deter communication among citizens. Corporatism creates conformists who behave like cogs in organizational hierarchies, not responsible citizens,” explains Publishers Weekly, reviewing the book Voltaire’s Bastards by John Ralston Saul. These are just some of the attributes of the ideology that has a strangle hold on our society and, it appears, on our major environmental groups as well.

The environment is too important to be left solely to the environmentalists.

Environmentalists with corporatist tendencies can cause a lot of harm when they are not properly scrutinized and held accountable by the public. They have played a huge role in keeping consumers in the dark regarding the hazards posed by CFLs. The Suzuki Foundation and Greenpeace claim that CFLs are good for the environment and no one dares to challenge them.

The disinformation process begins when public awareness of a harmful product, such as a CFL, is restricted by environmental groups. Over time, with no real criticism of the product, a consensus consciousness is created in the public mind that the product is safe.  Finally, in one of the oldest tricks in the book, corporations use these groups as third party endorsers to create a favourable image of a potentially dangerous product. Remember back in the sixties with doctors in TV adds smoking Camel cigarettes?

The evidence that shows that CFLs are hazardous to humans is undeniable. The question is, why are environmental groups willing to risk a safe environment and their reputations by promoting a toxic product?

CFLs Are A Hazardous Product & Do Not Save Energy

It may surprise many people to know that CFLs increase a consumer’s carbon footprint in a ‘cradle to grave’ analysis. Full costs to manufacture, operate and safely dispose of a CFL have never been disclosed to the public. The reality is that residential lighting takes up only 0.8% of energy consumption in Canada.

CFLs are energy hogs to produce, operate and dispose of. Reducing a consumer’s carbon footprint is the CFL’s raison d’être.  But before deciding to switch over to compact florescent lights it would be wise to first review a cradle to grave analysis of the carbon footprint of a CFL, compared to an incandescent bulb.

What is the real energy cost of a CFL?  What does it cost to mine, manufacture, package, ship, sell, operate, dispose of CFLs on the environment? These are questions ignored by CFL promoters.

An International Association for Energy-Efficient Lighting (IAEEL) study conducted in Denmark, explored some carbon footprint factors, but not all, showing it took 1.8 Kwh of electricity to assemble a CFL compared to 0.11 Kwh to assemble an incandescent bulb.  That means it took 16 times more energy to produce a CFL. The study did not include the fact that a CFL is much heavier and is more dangerous to handle, and will thus cost more to package, to ship, and to sell.

This research also did not calculate the energy required to safely dispose of a CFL and reclaim the mercury. The cost of removing mercury from the landfills was also not considered. More over, the potential cost in destroyed lives, illnesses, and lost human productivity due to exposure to mercury and electromagnetic radiation have not been considered.

If such a study could be done, and considered all the negative contributing factors, it would show a CFL has a massive carbon footprint, one that would dwarf a regular incandescent light bulb and it would also show that CFLs will leave behind a wake of environmental destruction.

CFLs Do Not Save On Energy Consumption

Power Factor
An incandescent bulb has a power factor of 1. Most CFLs sold in Canada have a power factor of about 0.55.  That means there are about 45% more energy losses in operating the CFL compared to an incandescent bulb.  This does not show up on a power bill but the power company has to supply about 45% more power than what the bulb is rated for. Astonishingly, CFLs can take almost twice as much energy to operate than what is on the label and still be listed as an energy star product, something few consumers know. CFL cheerleaders seldom tell consumers that the power factor is not included in their energy consumption calculations.

Heat Loss
Energy efficient bulbs increase greenhouse gases. Because they burn cooler, they cause home heating costs to rise. "Lighting regulations (banning incandescent lights) will increase GHG emissions in Hydro’s service territory by 45,000 tons due to cross effects of a switch to cool-burning bulbs,” explained a BC Hydro spokesperson in 2009 Vancouver Sun article.

The ‘cross effect’ referred to is the loss of heat from hotter incandescent bulbs when we switch over to cooler burning CFLs.  When a 60watt regular bulb is replaced with a 15 watt CFL, 45watts of heat from inside a house is lost. If that is repeated 20 times, 900watts of lost heat now has to be provided for from another source.

To make up for the lost heat consumers have to turn up electric heating, or worse still, turning up their oil or gas furnace which will leave them consuming even more energy and creating more greenhouse gases than before they made the switch.  In the summertime, because of longer natural daytime light, both lighting and heating are used much less. In the wintertime power consumption will rise as lights go on but additional substitution heat is required to compensate for less heat from the CFLs.

Considering the lower power factor as well as the heating losses, it can be concluded that using CFL will not reduce a consumer’s carbon footprint when compared to a regular light bulb. Moreover, instead of saving energy there is good evidence demonstrating that using CFLs will increase the user’s carbon footprint.

CFLs Are Power Dumb

Lighting is a fraction of overall energy consumption and has a limited potential for energy savings.  Nevertheless, North Americans should be conserving wherever possible.  At the same time, people should not forget that switching incandescent bulbs to CFLs poses a whole range of negative environmental and health impacts with very little, if any, energy savings

An electric hot water tank consumes five times as much electricity as residential lighting.

To put lighting energy consumption into perspective, the Sector Sustainability Table listed in the Government of Canada website reports that  “Homes consume 16% of all the energy used in Canada, with lighting using 5% of that figure. Residential lighting therefore represents 0.8% of the total energy consumption in Canada. This means that Canadians are spending millions of dollars on CFLs in a fruitless effort to reduce a fraction of their energy consumption.”

It would be much ‘power smarter’ to focus on residential water heating than light bulbs.  An electric hot water tank consumes five times as much electricity as residential lighting. If hot water heating was made 10% more efficient by using inexpensive technology already available, Canadians would save more energy than the most wildly optimistic predictions of savings by CFL promoters. It would be cheaper, simpler, and have no detrimental environmental effects.

CFLs Are Mercury Polluters

More than 98% of used CFLs end up in landfills each year. That is 675 million for the year 2007 according to the National Geographic Society. Each CFL contains about 5 milligrams of elemental mercury as well as other poisonous gases.  When mercury enters water sources, biological processes change the chemical form to methylmercury which is the organic, more toxic form found in fish.  Methylmercury bio-accumulates through the food chain and once in the body can affect developing fetuses, children and adult nervous systems.

Methylmercury will not stay in landfills as it easily gets transported through the water table. Throwing CFLs into landfills will contaminate the soil, the water table and eventually the air.

More than 60,000 children are born each year in the United States with neurodevelopment impairments caused by exposure in the womb to methylmercury compounds, according to new estimates by an expert panel convened by the National Academy of Science’s Year 2000.

Beware of a broken CFL, as each broken lamp should be considered similar to a toxic spill and care needs to be taken cleaning them up. The manufacturing of CFLs also exposes workers to toxic levels of mercury. CFLs are manufactured mostly in China with virtually no health, safety, or environmental protection regulations.  Ironically, most of the electricity used to manufacture CFLs comes from coal-fired generators. As CFLs increase in popularity, mercury exposure to workers, to electricians, to maintenance personal, to consumers, to water supplies, and to the living environment, will go ahead almost unchecked.

How many resources and pollutants does it take to make a light bulb?

 “The reality is, even energy-efficient products don’t always come from energy-efficient beginnings.  Consider for a second what goes into producing, powering and transporting products around the world like...energy efficient light bulbs. Until they are manufactured in a carbon-neutral way, transported on low-emission vehicles and powered in our homes by cleaner energy—green products will never be as green as they can be,” explained the World Wild Life Fund in MacLean’s Magazine.

Many environmentalists ignore these facts and instead claim that CFLs put less mercury into the environment than what would have been created via a smoke stack to generate the additional electricity needed for regular light bulbs.  This is not true.  Not all electricity is generated by dirty coal-fired plants. Even if it was, this would still be an irrelevant point given that coal fired power plants could operate with 80% less mercury emissions. In any event, it does not apply to BC where 90% of electrical power comes from hydroelectric dams according to BC Hydro. In Canada, 58% of electrical generation is from hydro and 19% from coal, according to Industry Canada.

CFLs Are Electro-Polluters

CFLs emit electromagnetic radiation, a type of energy that can make people very sick. Many people have reported skin rashes and irritation due to ultra-violet (UV) radiation. Radio frequency radiation is even more of a concern.  The effects of exposure to radio frequency radiation, as well as to high voltage spikes and transients, are known to cause illness, are virtually ignored by environmental groups and green building consultants alike.

There has been a ‘rash’ of health problems associated with exposure to electromagnetic radiation such as that emitted by CFLs.

In Sweden, according to polls, up to 290,000 people, or more than 3% of the population, have reported suffering symptoms of EHS when exposed to electromagnetic radiation.  Symptoms range from joint stiffness, chronic fatigue, headaches, tinnitus, respiratory, gastric, skin, sleep and memory problems, depressive tendencies, to Alzheimer’s disease and all classes of cancer.

Hope For The Future

Other than the World Wildlife Fund, almost all the major environmental groups have not informed the public about the dark side of CFLs. Why they behave as they do is unknown but promoting CFLs could potentially diminish these groups credibility when the facts become apparent.

Hopefully, other governments will wake up to the shortcomings of CFLs, and follow the New Zealand government’s example and change their policies on banning incandescent lights due to concerns about safety and energy efficiency of the CFLs. Germany has already restricted the use of fluorescent lighting in public places and has banned fluorescent lights in hospitals perhaps showing that this issue is too great to be shrugged off and ignored. North America appears to be headed in the opposite direction and the Canadian Federal government still plans to ban all incandescent lights before year 2012.

There are incandescent light bulbs on the market right now that last longer than CFLs and are 80% more efficient than a regular bulb.  In 2010, surprisingly, just as the market gets saturated with CFLs, General Electric is coming out with a new high efficiency incandescent bulb. They claim it will be twice as efficient as a regular bulb.

If they live up to their claims these new incandescent lights will rival CFLs for energy consumption, but will not have all the other environmental problems. Then another buying craze will begin and CFLs may begin to be phased out, leaving behind a long-term problem of mercury disposal, remediation, and an untold toll on human health.

In the meantime, the best way for you to reduce your carbon footprint is to follow your mother’s advice and turn the lights off when you leave the room.

Walt, even if CFLs were good, a ban would still be wrong!

Americans choose to buy ordinary light bulbs around 9 times out of 10.
Banning what Americans want gives the supposed savings - no point in banning an impopular product!

If new LED lights -or improved CFLs- are good,
people will buy them - no need to ban ordinary light bulbs (little point).
If they are not good, people will not buy them - no need to ban ordinary light bulbs (no point).
The arrival of the transistor didn't mean that more energy using radio tubes had to be banned... they were bought less anyway.

All lights have their advantages
The ordinary simple light bulb has for many people a pleasing appearance, it responds quickly with bright broad spectrum light, is easy to use with dimmers and other equipment, can come in small sizes, and has safely been used for over 100 years.

100 W+ equivalent brightness is a particular issue - difficult and expensive with both fluorescents and LEDS - yet such incandescent bulbs are first in line for banning 2012!

Energy?
Since when does America need to save on electricity?
There is no energy shortage, there are plenty of local energy sources, Middle East oil is not used for electricity generation.
Consumers - not politicians - pay for the energy used.
Certainly it is good to let people know how they can save energy and money - but why force them to do it?


Emissions?
OK: Does a light bulb give out any gases?
Power stations might not either: In Canada British Columbia, Manitoba, Quebec,
and in USA Washington state practically all electricity is emission-free, while around half of it is in states like New York and California.
Why should emission-free households be denied the use of lighting they obviously want to use?
Low emission households will increase everywhere, since emissions will be reduced anyway through the planned use of coal/gas processing technology or energy substitution.

Taxation:
If a reduction in use was needed (it isn't), then taxation to reduce consumption would make more sense since government can use the income to reduce emissions (home insulation schemes, renewable projects etc) more than any remaining product use causes such problems. People can still buy what they want, unlike with bans. However taxation is in principle wrong too,
at least on electrical appliances, for similar reasons to bans.

Great article! I had suspected their evils from the very start! I was disappointed with the proposed solution, (turn out the lights when you leave the room). Suggestions of what brands & models of bulbs to buy in the meantime would be exponentially more helpful.

Hope you decide to post something along those lines! I can't just live without light until GE's new bulb comes out!

Your 'power factor' part of your diatribe is BS. A bulb will consume a certain amperage at a given voltage. A watt meter is the ultimate harbinger of energy consumption 'bad news', and my direct measurements of a variety of consumer CLFs here in the states rates them within 1% of their rated wattage (roughly, W = V x A, although electrical engineers cringe when it is that simplified). I buy my power on the basis of kilowatt-hours. Every watt I consume, I buy. The CLFs produce roughly 3.5x the number of lumens (light density) as a regular bulb for the same wattage. I can run a CLF 3.5x longer for the same cost in consumed electricity as a regular bulb. The rest of your post grandstands but smells of F.U.D. Please back up your other claims with science, not politics.

Many of us have known for years, from working under fluorescent lighting, that the energy output is debilitating to humans, and probably other living things. It ain't all about MONEY...
written by victoria , September 27, 2009
Did you just take a bunch of facts and figures from a bunch of newspaper clippings and articles and plaster them all into this article of yours?

The study in Denmark that you get your manufacturing figures from actually concludes that using CFLs over incandescent lighting reduces the total carbon emissions. But obviously you didn't bother to read the entire article. If you bothered to read the rest of it, you'd have noticed that comparisons were made based on the amount of light output in order to scale the lifetime and different lumens outputs of each bulb properly. This comparison shows that even your manufacturing numbers that you worship don't mean that much, because per lumen-hour, the CFL requires less energy to produce.
written by Wilson , November 07, 2009
Regarding Wilson's comment.

.

The Denmark study did not do a cradle to grave analysis on the carbon foot print of a CFL. They just compared the manufacturing costs of an incandescent lamp compared to a compact fluorescent lamp. With that very limited examination they still came up with the cfl costing 17 times the regular lamp. If they had examined the true costs of a CFL it would show to cost 100's of times more than a regular incandescent lamp over it's lifetime. Their claim that CFL's saved energy over incandescent lamps simply is not supported by their data.

What a bunch of fear mongering!

I don't think CFBs are without their problems, but this blog is a mix of ignorance, vituperative, and old-fashioned fear. Why? What axe do you have to grind here?

For example, do you actually understand what "power factor" is? Do you realize that the grid is largely inductive, and the capacitive load of CFBs actually help the utility correct for power factor? And of course, you do realize that utilities routinely CORRECT for power factor? The "45% more energy losses" is just total bull. Have you even taken a basic electronic theory class? Well, I'm an electrical engineer who is buying none of your technical arguments, they are so full of holes. For example, how can you insinuate that ultra-violet radiation is the same hazard as the ultra-sonic radiation from CFBs -- and keep a straight face? I've put a spectrum analyzer on a CFB. You get a million times (~60 decibels) more "radiation" when you use a cell phone, and hundreds of times (~20 db) more "radiation" when you drive by a cell phone tower.

Like I said, CFBs are not without their problems. Mercury certainly is one, and the complex, long supply chain is another. But by indulging in hyperbole in a fact-free manner, you do your cause no honour.
written by Jan Steinman , December 26, 2009
Regarding Jans comment.

Power Factor, simply put is a % of how efficiently the AC power is being used. With a power factor of 50%, double the current would flow. For example, a 40 watt incandescent lamp draws 0.33 amps. (40 watts / 120 volts = 0.33 amps) This bulb, being a resistive load, has a power factor of 100%. A single tube fluorescent lamp rated at 40 watts may draw double the current of the 40 watt incandescent, but still only use 40 watts of real power. This fixture has a power factor of 50%.

How well utility companies are able to correct for power factor, how much energy is actually lost and at what cost is of concern. So just how much more water has to flow over the dam? If Jan can supply that information I would gladly look at it. But there are energy losses, it does cost money to correct power factor, and that cost does get passed on to the consumer. If I have over estimated these costs I will gladly correct this in the article.

Ultra violet radiation poses a serious threat to human health. That we can agree upon. As for the radio frequency radiation that is emitted from a CFL as well as transients, I recommend visiting web sites with postings by Dr Magda Havas on this subject. I did not insinuate that they are the same.

Cellular telephones operate at a much higher frequency in gigahertz ,or billions of cycles per second. They also pose health hazards. Many researchers agree that power density is not the only cause for concern but the frequency may be a even more important factor. Although there are similar responses by the body to different frequencies I would not compare a compact fluorescent light with a cellular telephone.
To say that this article is bull or that I am fear mongering is Jan's opinion. As far as I am aware electrical engineers have about the same amount of formal education and training as I have on the biological effects of non thermal levels of exposure to living organisms by non-ionizing electromagnetic radiation.

None.

Have a great year everyone,

re: Heat Loss
Saying that CFLs are bad because they don't waste energy (e.g. produce excess heat) is incredulous. It's like saying that the fact that this computer is more efficient than a giant mainframe I'm doing the environment a disservice. After all, this computer is producing less heat than an older one would, so I pay for it. But the way this computer produces heat is pretty inefficient compared to a space heater, so you don't want to use it in place of one unless you want it's main function (being a computer). Furthermore heat generally rises, so the lightbulb on the ceiling isn't really doing much other than heating your roof up whereas your heater will actually warm the room (and more efficiently too).

Of course all this on top of the most obvious point, you ignore times when heating would be undesired... say when the A/C is running? However much heating that bulb provided during the winter, you now have to deal with it during the summer.

Apparently you missed in the study where it stated the production footprint was less than 1% of the operating footprint. Furthermore, while the cost to make one CFL is more than one incandescent, that CFL lasts longer, long enough that according to the study that it makes their production costs comparable. (This is why using 100 plastic bags is worse than using 1 reusable container)

Power Factor: You confuse it with actually requiring the rating/pf amount. It doesn't actually consume that power though, but your right the electricity company does need to generate it on their end, however that extra energy just doesn't then just magically disappear. The real losses are from the transmission of the power. So while there are extra costs, it isn't a 2:1 loss as suggested by the power factor. If I recall correctly transmission line loss is around 1/3 of the power. So of that extra power that needed to be sent, you're losing a third of it which can be factored into the CFL's true power cost.

Of course the truth still is that a light that is off wastes the least energy

I have just realised after reading your information ,that in fact my burning skin and headaches and nausea are a result of exposure to the "obligatory" new lightbulbs. They are everywhere, in public transport, in supermarkets in the school where I work. I will now try to avoid this radiation, but what about the millions of people including children who don't "feel" the problem but who are receiving unnecessary radiation all day and every day. What can we do?

CFL's and all the rest of the greenwashing is just B.S.

As for CFL's,,, here is what I know:

1. From the beginning the manufactures have indicated a life span of 7 to 10 times a regular bulb. More B.S. I have used these things from the start ( about 7 years ago) and have replaced all lamps at least once and others over 3 times. I now write the date on each lamp to get replacements.

2. CFL's emit radio energy at the frequency of marine emergency radios. Most packages warn to never use these bulbs in these facilities. I know a ham who made a low wattage transmitter out of these things. What will the cops do in waterfront cities when no more regualr bulbs are allowed in 2012.

3. Ever notice that most CFL's are made in CHINA ?? I have good reason to believe that the Chinese cfl industry is lobbying governments worldwide to ban regular bulbs thereby forcing countries to use their products. This happens in Canada because we would not want to offend our little ASIAN criminal brothers,,,,would we?

My way to fight this product is to stockpile as many regular lamps as I can before 2012.

re: csdx , January 10, 2010

Regular heat producing bulbs in the ceiling distribute their heat when the fan is running in the furnace. That is why heat circulates in a house. CFL's DO NOT run cool. I recently burnt my finger when trying to remove one that had just burn out. Finally the A/C point. In Canada we have very LONG days in the summer which means our houses are naturally lit a very large percentage of the time. With sunlight streaming in you don't need any bulbs.

The real bottom line is that lighting a house is a VERY small consumer of power and not even worth considering. This means that it is a non issue except to the Chinese who want use to use THEIR product exclusively.
