Save Energy -- Switch to Compact Fluorescent Bulbs (CFLs)

If you haven't already, replace your household light bulbs with Compact Fluorescent versions. If every American home switched just one bulb, it would reduce greenhouse gas emissions the same as pulling 800,000 cars off the road.

As opposed to incandescent bulbs, CFL's last up to 10 times longer, use about 75-percent less energy, and will save you around $30 over its lifetime.

On the downside, they contain poisonous mercury and therefore need to be recycled instead of thrown in the garbage, which can be a hassle. If they break, it's trouble, but you can visit Energystar.gov for cleanup instructions.

LED Light Bulbs That Last 60 Years to Get Cheaper

Super-Efficient LED Bulbs to Get Cheaper
Those old-school incandescent bulbs you grew up with are on their way out, deemed too inefficient for a continued life in today's eco-friendly society. But their replacements, compact flourescent (CFL), have their own share of issues. Some people find that the next-gen bulbs give them headaches, and since each one contains a bit of mercury they aren't exactly green themselves. For that reason, many have seen LEDs as a possible replacement, but they have their issues, too, primary among them being cost. That could change thanks to a British professor's newest tech, which could make the bulbs considerably cheaper.

LEDs are small and don't give off much light, but they last for literally decades (like, 60 years) and give off virtually no heat, making them three times more efficient than the twisty CFL bulbs. Professor Colin Humphreys at Cambridge University has come up with a way to make them far cheaper than normal, creating a more efficient way to produce gallium nitride, a material required for the production of LEDs. His discovery could pave the way to LED bulbs that cost less than $5 a pop. However, we're still at least a few years away before these could go into mass production, meaning you're going to have to keep hitting the Asprin or guiltily using your old incandescent bulbs.

Seven Lazy Ways to Go Green



If "going green" sounds great but not quite groovy enough to "get off the sofa," Unplggd has compiled seven ways for you to do some good without doing too much ... anything. The tips range from recycling your obsolete gadgets to swapping out your incandescent bulbs for energy-saving CFL alternatives (which use 80 percent less energy).
Some tips are a bit obvious ("wash your clothes on lower heat settings!"), but they're all practical and you should really be following them.

Oh, and there's water-saving option in there as well. If you've got an old toilet, you can save water every time you pee: simply put a water bottle filled with water into your cistern to bring it up to date. Pottytime! [Source: Unplggd]

Recycling of Compact Fluorescent Bulbs Neither Common Nor Easy Enough

Recycling of Compact Fluorescent Bulbs Not Common or Easy EnoughMany of us have starting loading our homes with compact fluorescent bulbs (CFLs) looking to go green, and save some green in the process. But there's a problem -- it turns out that compact fluorescent bulbs contain a small amount of mercury, which means that the bulbs must be recycled properly and can't just be thrown out with the rest of the trash. Most cities, however, do not have recycling programs in place for them, or require that residents drive out to landfills to turn in the bulbs themselves. So the bulbs land in the garbage, completely undoing all of the intended good for the environment.

In some places, retailers are stepping in to fill the void in the recycling program, though the job may become too costly for all but the largest of chain store to offer the service as the need to recycle the bulbs increases.

A group at Brown University has suggested making special packaging which CFLs would be sold in, then packed back into and mailed in for recycling. The packaging would be cushioned against breakage and contain special mercury absorbent materials in case it did shatter.

There is no clear solution at the moment, but something must be done soon before CFLs become an environmental hazard. [source: AOL News]

Inventors Create Pill-Sized Bulb That's Brighter Than a Street Lamp


Alternative lighting solutions are all the rage right now. People are finally realizing that a big, clunky incandescent light bulb, which gets so hot it burns your hand, is not a particularly efficient way to illuminate a room. But despite the quick rush to change over to compact fluorescent (CFL), concerns over the potential health impacts and mercury content in CFLs are driving folks to look for other alternatives, and a little bulb the size of a Tic Tac may be the solution.

The bulb, filled with argon gas, pumps out an impressive 140 lumens (the standard way of measuring the efficiency of a bulb) of light per watt. More lumens per watt means that more of the electricity that is pulled in to the bulb is turned into light instead of being wasted as heat.

The current champion in the lighting world, the LED, can pump out 70 lumens per watt. Compact fluorescent blubs clock in at around 50 per watt, while the standard incandescent bulb offers a measly 15. On top of that, one tiny little argon bulb can crank out 35,000 lumens, plenty enough to act as a street lamp.

Is this the future of lighting? That, of course, depends on cost and lifespan.

Energy-Saving Bulbs Causing Migraine Headaches

Compact Fluorescent Bulbs Causing Migraine HeadachesCompact fluorescent bulbs, the twisted looking replacement lights that use as little as one fourth the power of their common incandescent counterparts (and last much longer), are being adopted worldwide in an effort to reduce energy consumption. They are even becoming mandatory in some countries -- a little troubling according to the Daily Mail, which reports that health experts in the U.K. say the green bulbs can cause migraine headaches or other disconcerting symptoms in many people.

The bulbs work in the same way as the long, traditional fluorescent tube lights seen in many commercial establishments. This means that they can produce light that subtly flickers, unnoticeable by many, but a big problem for others, especially epileptics, who can suffer from seizures under fluorescent bulbs. According the U.K.'s Migraine Action Association and other health organizations, the lights also cause headaches, as well as nausea, dizziness, and even physical pain for those suffering with lupus, according to the study.

In both the United States and the United Kingdom, traditional incandescent bulbs are set to be completely phased out by 2012. Surely those with medical conditions can be given exemptions easily enough, but if they can't simply walk into a store and buy a traditional bulb, just how many companies will continue manufacturing them and how much will they cost? Will traditional bulb clubs be the marijuana-buying clubs of the 21st century?

Such recent health concerns around energy-saving fluorescent bulbs might be another reason to push research into production of LED-based lighting options, which are even more efficient than CFL lighting, and even more durable, with a single bulb potentially never burning out. Such LED-based bulbs are available now, but at per-bulb costs that dwarf those of the relatively expensive CFL bulbs.
