Bulb brilliance at Wal-Mart as CFLs go mainstream




AEN News





By Gregory M. Lamb



While governments in Australia and Britain are mandating a changeover to compact fluorescent lights (CFLs), the United States appears to be doing it free-market style. Wal-Mart just announced it will sell its own low-cost house brand of CFL lights, while also trumpeting that it had already reached its goal of selling 100 million of the swirly, energy-efficient bulbs this year.

But that's just the beginning: From laundry detergent to DVDs, toothpaste to vacuum cleaners, the world's biggest retailer seems committed to "going green" product by product. In the process, it's beginning to reverse some of the bad publicity it has received over selling cheap goods from China and allegations of labor abuses.

Bulb brilliance at Wal-Mart as CFLs go mainstream








By Gregory M. Lamb





While governments in Australia and Britain are mandating a changeover to compact fluorescent lights (CFLs), the United States appears to be doing it free-market style. Wal-Mart just announced it will sell its own low-cost house brand of CFL lights, while also trumpeting that it had already reached its goal of selling 100 million of the swirly, energy-efficient bulbs this year.

But that's just the beginning: From laundry detergent to DVDs, toothpaste to vacuum cleaners, the world's biggest retailer seems committed to "going green" product by product. In the process, it's beginning to reverse some of the bad publicity it has received over selling cheap goods from China and allegations of labor abuses.

It's won plaudits from global-warming activist Al Gore and former President Bill Clinton, who invited Wal-Mart's CEO to the high-profile Clinton Global Initiative meeting in New York last week. The speculation now centers on whether Wal-Mart's massive buying influence on suppliers will spread the fight against global warming beyond the granola-crunching set to the minivan masses.

Environmental groups are expressing cautious optimism, according to a story in BusinessWeek. Many remain suspicious that the move is no more than a public-relations ploy. But even the "greenest of the greens," the article reports, concede that with $350 billion in yearly sales, Wal-Mart has the potential to change the marketplace. But will it be willing to cut off suppliers that refuse to cooperate? That remains to be seen.

Says Kert Davies, research director at Greenpeace:

"Wal-Mart has the power to coax suppliers into changing. They're taking on a daunting task, which is pretty cool."

In promoting its CFL program, Wal-Mart offered some eye-popping statistics last year: Nearly 20 percent of all home electric costs stem from lighting, it said, and changing a single conventional 60-watt bulb to a 13-watt CFL saves an average of $30 in electric costs over its lifetime. Because it will last so much longer than a conventional bulb, a CFL will also "prevent 10 conventional bulbs from being produced, transported, and discarded in a landfill; 220 lbs. of coal from being burned; and 450 lbs. of greenhouse gases from reaching the air."

Andy Ruben, Wal-Mart's vice president of corporate strategy and sustainability, added on its website:

"Over the life of those [100 million] bulbs, $3 billion can be saved in electrical costs and 20 million metric tons of greenhouse gases can be prevented from entering our atmosphere. This change is comparable to taking 700,000 cars off the road, or powering 450,000 single-family homes."

CFLs contain tiny amounts of mercury, a toxic element, which has caused concerns that they might be hazardous in homes. But their net effect is to reduce the total amount of mercury emitted in the environment, explains a story in the Akron Beacon-Journal:

"... [I]t's important to factor in the mercury that coal-fired power plants emit in producing the electricity to power our light bulbs. In making the electricity to power a CFL over its lifetime, a plant would release 3.3 milligrams of mercury, but it would emit 13.6 milligrams over that same period to power incandescent bulbs, the [federal government's] Energy Star program says. Add the amount of mercury contained in the CFL to the amount released in producing the power, and it's still only 61 percent of the mercury attributable to [conventional] incandescent bulbs."

The bulbs should be treated as hazardous waste and not tossed into the trash, the article concludes.

Wal-Mart is working with its suppliers, including General Electric, to cut the mercury content in its brand of CFL bulbs, according to Reuters. It's also doing something it's done for a long time: undercutting its competitors' prices by selling Wal-Mart-brand CFL four-packs at the same price as a brand-name three-pack. More than safety concerns, the biggest hurdle to wider consumer acceptance is the price of CFL bulbs, which cost much more up front than conventional bulbs, even though consumers save money in the long run through energy savings.

Duke Energy has begun a pilot program in the Cincinnati area offering coupons worth $3 off a package of CFL bulbs at Wal-Mart, lowering the price to $1.50 per bulb, according to a story in the Cincinnati Inquirer. At Clinton's meeting last week, Duke and seven other electric utilities representing 20 million customers in 22 states pledged to increase their spending on energy-efficiency programs by $500 million to $1.5 billion in the next few years through regulatory reforms and approvals.

The effect over the next 10 years would be equal to removing 6 million cars from the nation's roads, according to the article. Clinton, it reported, applauded the effort, calling it "a huge deal in the way we approach the challenge of climate change."

Liposuction doctor uses human fat to fuel car - loses license as a result

Sunday 28 December 2008 at 6:27 pm Los Angeles - A California liposuction doctor has lost his license to practice after being busted for using human fat he sucked out of patients bodies to fuel his car. As it turns out, using human medical waste in California is illegal.

Doctor Craig Bittner, who operated a fat clinic in Beverly Hills, California up until November when he was shut down for his morbid use of human body fat, was creating what he called "lipodiesel" out of the human waste collected from his clinic's liposuction practice. more

Defatted soy flour eyed as filler for rubber tires

Sunday 28 December 2008 at 6:08 pm Washington - In 1941, Henry Ford unveiled a plastic-bodied car whose panels included soybean meal as component. The feat made headlines--and history--but the idea never took off commercially. However, researchers continue to toy with the idea, including (ARS) scientists Lei Jong and Jeffrey Byars, who are testing soy flour as a "green" filler for tires and other natural rubber products.

Today's fillers are typically petroleum-based particles called "carbon black." Tire manufacturers use them in rubber to improve tensile strength and wear resistance. But petroleum's many competing uses, rising costs and ties to pollution have rekindled interest in biobased alternatives, especially those derived from homegrown crops like soybeans.

Soy flour is primarily used in cooking and baking. But Jong and Byars' studies at the ARS Cereal Products and Food Science Research Unit in Peoria, Ill., indicate the flour also could serve as an inexpensive alternative to today's carbon-black tire fillers.

The researchers use defatted soy flour that's been dispersed in water to form aggregates 10 microns in diameter (about 1/1000th of an inch). Then they add the aggregates to rubber latex and freeze-dry the mixture. This causes the aggregates to form a tight interconnecting network through the rubber.

For lab tests, the researchers mold the soy-based rubber into samples and subject them to shearing and other forces. Of particular interest is the "storage modulus," which measures the elasticity of a material. On average, the storage modulus scores of composites containing 30 percent soy flour are 20 times higher than filler-free rubber, but somewhat lower than those reinforced with carbon black.

In addition to testing other biobased filler materials, the researchers are collaborating with rubber manufacturers to further explore the technology.

A report on the research was recently published online in the Journal of Applied Polymer Science. more

Arctic ice melt accelerating, scientists say

Toward a greener economy

Friday 17 October 2008 at 2:55 pm Toward a greener economy




By Moises Velasquez-Manoff





New York - Market bubbles occur when goods are traded at prices that greatly exceed real value. They burst when they grow so bloated that they become unstable. The current economic turmoil, widely viewed as the worst since 1929, is one example of what can happen when the difference between market value and actual value becomes too great.

Environmentally minded economists have long warned that equally burstable ecological bubbles can occur if humanity lives beyond earth's capacity to regenerate. The problem, they say, is that we're addicted to economic growth. Mainstream economics assumes that the economy, the engine of modern civilization, can grow perpetually. more

Precedent-setting carbon auction Thursday

Monday 29 September 2008 at 02:43 am By Mark Clayton


For almost as long as people have worried about global warming, economists have called for taxing carbon emissions. As long as sending CO2 skyward was cost-free, they argued, the practice would continue.

Starting Sept. 25, for the first time in US history, a price tag will begin to be placed on millions of tons of carbon dioxide spewing from every major power plant from Maine to Maryland.

Just what that price will be won't be known until after Thursday's computerized auction of about 12.5 million tons of "carbon allowances," essentially permission slips to pollute.

Utility companies will bid on the allowances. They may be used, saved, or traded so that any company with a need to send more CO2 up the stack can buy more - at the market price. The amount of CO2 to be cut over the next decade is modest - about 18 million tons annually (US power plants collectively emit about 2.8 billion tons of CO2 yearly). But the auction and process of setting a price for carbon are critical first steps, many say. more

Dispelling The “Twisted Truths” Of Energy-Saving Light Bulbs

Saturday 13 September 2008 at 5:18 pm Dispelling The “Twisted Truths” Of Energy-Saving Light Bulbs







For more than 129 years, people have used the incandescent light bulb as the primary light source for the home. With more consumers searching for products that are good for the environment, a new light bulb is revolutionizing lighting around the world. Energy-saving compact fluorescent light bulbs (CFLs) have become the symbol of the “green” movement. They use 75 percent less energy and last as much as 10 times longer than traditional incandescent light bulbs. Plus, they help reduce carbon dioxide emissions linked to global warming. more

Campaign Plants Trees At Schools Across The U.S.

Saturday 13 September 2008 at 5:08 pm Campaign Plants Trees At Schools Across The U.S.






Schools are generally seen as the place to plant the seeds of knowledge. Yet thanks to a one-day environmental campaign, schools and parks across the country became places to plant something a little greener.

Sixteen schools across the country, from Long Island to Hawaii, participated in the initial “Trees for Success” campaign, with more than 800 trees planted in schools and neighboring parks in a single day. The schools were selected by the Arbor Day Foundation out of more than 200 applications based on need, civic and local support, student involvement, a plan for upkeep, and location. more
