Never Mind the New York Times - Buy a Compact Fluorescent Lightbulb

buy a compact fluorescent light bulb.An article in the March 28 New York Times contained some pretty unflattering remarks about compact fluorescent light bulbs.  Since the bulbs were never given a chance to speak in their own defense, I guess it’s up to us fluorescent bulb-huggers to speak for them.  So, here goes.

“Poop Humour” Counterproductive to Biogas Technology

The biogas process, which produces fuel from animal and human waste, is prompting many supposedly amusing posts that could have a negative effect. Googling “biogas and poop” gives 12 800 hits including The Power of Poop, California Cow Poop Power and Turning Cow Poop into Car Power. This is counter productive as it distracts from the potential that biogas holds for both developing and developed countries.

Bacteria

Besides the comical slant of the titles, it is surprising that biogas is often presented as something amazing & unknown although it has been around for hundreds of years, is used in tens of millions of rural household and is a significant contributor to Europe’s renewable energy production.

Biogas - Amazing Natural Technology

The fermentation of organic material such as biomass, manure, sewage, farm waste, municipal waste, green waste and energy crops in the absence of air produces biogas. The same anaerobic fermentation produces swamp, marsh and landfill methane.

New $3 LED Bulb Lasts 60 Years

The battle between CFL and LED bulbs may finally be over thanks to researchers at Cambridge University who have developed a $3 LED bulb that lasts for 60 years. The bulb, which is smaller than a penny, is 12 times more efficient than tungsten bulbs and three times more efficient than fluorescent bulbs.

Researchers Develop Super-Efficient LED Light

LED light bulbs are already more efficient than your average bulb, but researchers at the Renssalaer Polytechnic Institute have developed a new kind of LED that exhibits both improved energy efficiency and lighting performance. The researchers‘ polarization-matching LED shows an 18 percent increase in light output and a 22 percent increase in wall plug efficiency (the amount of electricity that the LED converts into light).

Study Proves Light Pollution Can Kill Animals

A groundbreaking study has proved that man-made light sources can change natural light cycles, triggering abnormal animal behavior that often leads to injury and even death.

The study, published in the journal Frontiers in Ecology and the Environment, confirms that polarized light pollution can cause confusion in creatures that rely on light ‘cues’ to navigate through their environment, with many animals also thrown off course by light reflecting from buildings.

Ultracapacitator Flashlight Charges in 90 Seconds, Doesn’t Use Batteries

I’m always on the lookout for dependable flashlights, so the upcoming release of 5.11 Tactical’s Light for Life has really piqued my interest. Instead of batteries, the flashlight uses an ultracapacitator to hold its charge.

Look into the Light: the CFL

compact fluorescent lightbulb (cfl) on green backgroundIf you ask Simran about compact florescent light bulbs, she may crack one open and cut you. Not really, that would scatter mercury, but she is loca for the light bulbs. Check Monday’s Huffington Post for the full version of this post.

People give you this whole rap about how easy saving the planet is. Change a light bulb and save the world. Yes and no. How about we consider it a start rather than an end destination?

Lighting accounts for about 20% of our electric bills. Traditional bulbs burn heat rather than light, so are extremely inefficient. Compact florescent light bulbs (CFLs) are 80% more efficient and can last up to 10 times longer than a traditional bulb. Last December, Congress voted to phase out the inefficient incandescent. By 2012, the 100-watt bulb will be history.

In the interim, environmentally-minded folks of all ilks are heralding the bulb. The virtual Stop Global Warming march reminds us swapping out three incandescent bulbs for CFLs will save us 300 lbs. of carbon dioxide and $60 a year. The Coalition On the Environment and Jewish Life suggests installing CFLs for Hanukkah as a way to redefine “energy-stretching light” and reflect environmental stewardship. Students in Pennsylvania sell light bulbs instead of candy to raise money for their schools. (Simran prefers candy.)

Environmental Defense Fund: Easy Recycling of Compact Fluorescent Light Bulbs

CFL light bulbCompact fluorescent light bulbs (CFLs) use 75 percent less electricity than incandescent light bulbs for the same amount of light. (For why, see Bill’s post “Why Switch to Compact Fluorescents“.) But some people fear CFLs because of the tiny amount of mercury they contain. The risk from a broken CFL is extremely small, but CFLs should be disposed of properly so landfills aren’t polluted. Sealing used bulbs [...]

Korea Shines for Compact Fluorescent Use

korea-cfls.jpgAt night, South Korea is literally aglow. When the sun goes down you’ll find a vibrant night life of kareoke (”norebang”), street markets, and sujo bars. Still, per person, Koreans use only a little over half the energy used in the United States. How do they manage to light up the night–every night–and still save energy?

Part of the answer might be South Korea’s high usage of compact fluorescent light bulbs (CFLs).

It took me almost two months of living in Korea before I saw my first incandescent (”old fashioned”) light bulb. All of the others were energy efficient CFLs, like the one pictured here at this outdoor market.

LED tea lights!

Found these LED tea lights, and they’re awesome, and it’s a good deal!

No more using up lots of wax tea lights, no more blown-out flames, no more burning risks, hopefully no more toxins!

Tip o’ the Day: A Bright Idea

Have you heard this one before? "A light bulb walks into a bar…" Wait, that's not right. Let's try it again, "What's bright and light and white all over?" Okay, we're not the best joke tellers in the world, but we do know the punchline: CFL.

Switching over to compact fluorescent light bulbs (CFLs) is one of those solutions that is so simple and so effective, we all just need to do it. Says
