Consumer electronics going green

All those neat high-tech electronic gadgets we use often are consuming energy even when we aren't using them. Most use low levels of power to retain settings, power indicator lights, maintain connectivity and stay ready to use instantly when we pick them up.

According to Jennifer Amann, consumer electronics expert for the American Council for an Energy Efficient Economy in Washington said "What most people don't know is that consumer electronics use considerable energy when in standby mode or even turned off. That downtime flow maintains internal clocks, indicator lights, preference settings, remote control responsiveness and other features and accounts for about 40 percent of electronics power consumption." A separate Ecos report due out in September will provide more information on this issue.

Electronics Going green
Makers of computers, MP3 players and other popular gadgets are heeding consumers' call to be eco-friendly. New devices use less energy, have fewer toxins and are easier to recycle. The companies' challenge? To lower prices.

Mark Pierce of Lenovo was jolted in August when Greenpeace ranked the Chinese-American PC maker dead last for green credentials out of 14 consumer electronics brands.

Pierce, Lenovo's environmental chief, was duty-bound to fix the situation or risk the company's fledgling U.S. image -- it had recently opened new world headquarters in Morrisville.

He began meeting regularly with Greenpeace officials to determine what Lenovo needed to do. The company committed to phase out hazardous chemicals from all products by 2009 and initiated a global hardware recycling program. It worked. Within a year Lenovo had soared to the top of Greenpeace's quarterly chart and has remained near the top since.

The intensity of that turnaround exemplifies the fervor of consumer-electronics makers to be green, or at least be considered so. For the first time, virtually all major brands including Dell, HP, Apple, Sony and Motorola are ramping up efforts to put cleaner, more efficient and more easily recyclable products in stores.

Even Wal-Mart goes green

Whether you like Wal-Mart stores or not, the company, like many others, is implementing green technology to save costs and be more environmentally friendly. That's good for Wal-Mart and good for everyone else. Turning off lights and tv's during late night hours are visible steps to help save energy. Some of the major savings realized are:

* By selling recycled cardboard and plastic, Wal-Mart stands to make $28 million a year.
* By reducing packaging on its Kid Connection toy line, Wal-Mart will use 720 fewer freight containers per year, saving $3.5 million a year.
* By simply changing light bulbs in its ceiling fan displays to energy-efficient, compact fluorescent lights, Wal-Mart stands to save $7 million a year.

Wal-Mart cutting energy use
Rethink, reuse, reduce waste - Changes affect stores worldwide

Wal-Mart stores are turning off their TVs and dimming the lights between midnight and 6 a.m.

Those are just two of the dozens of changes the company is making as part of an aggressive plan to reduce waste and make its stores more environmentally friendly.

The green initiative will save Wal-Mart millions on energy bills and in some cases reap it a tidy profit.

And, like most things the giant retailer does, it's having a big ripple effect throughout the retailing industry.

Manufacturers are changing product designs to comply with Wal-Mart's changing demands.

Suppliers are changing distribution routes to help save gas.

And smaller food markets that did not directly compete with Wal-Mart are suddenly facing the retailer's notoriously strong muscle head on. Read more...

Nuclear power in North Carolina

Nuclear foes see danger in waste
Harris plant starts relicensing process

The Shearon Harris nuclear plant has long drawn scrutiny over the safety of atomic power. But safety concerns are shifting to an emerging issue: the buildup of radioactive waste at the site in volumes never anticipated when the plant began operating 20 years ago.

Longtime nuclear critics plan to highlight the nuclear waste quandary during a two-year safety review as Progress Energy seeks to extend the Shearon Harris operating license into the middle of the century. The Nuclear Regulatory Commission will hold the first public meeting on the Shearon Harris relicensing on Wednesday in Apex.

The nuclear waste issue is gaining momentum nationwide amid growing concerns that nuclear plants are potential targets for terrorism and sabotage. With no long-term solution in sight for disposing of nuclear waste, many nuclear plants are storing three times as much waste as the temporary pools were originally expected to hold. Unlike the nuclear reactors themselves, the storage sites usually are not heavily fortified against attack. Read more...

Green top suggested for Lowe's building

CROWMELL - An environmental analysis of the proposed Lowe's store has suggested the store have a "green" roof - have grass, plants, and/or flowers growing on the roof.

Lowe's is preparing to resubmit its application to build a 152,000 square-foot store on the north side of Route 372. The North Carolina-based home improvement company is scheduled to go before the Inland Wetlands Commission Wednesday as it renews its request for approval.

A similar proposal last year fell just short of approval.
As part of the preparation for the submission to Inland Wetlands, a copy of the Lowe's proposal was submitted to the Connecticut River Coastal Conservation District for review and comment.

The district responded with a four-page analysis of the proposal, and included a series of recommendations intended to reduce the amount of storm water runoff that is discharged into surrounding water courses.

Included in the analysis, near the top of page 3, is a suggestion that "serious consideration should be given for a vegetated roof...for at least a portion of the building."

The analysis notes the roof of the proposed building is equal to 3.3 acres.
"Vegetation on a roof captures a significant amount (of) rainfall, thereby reducing runoff."

A "green roof" can mean just that a roof painted green. Or, it can mean what is in essence a lawn or a garden growing on the roof.

There is even a Web site - greenroof.com - that explains the concept.

There are two types of green roofs: intensive or extensive, the Web sites explains.
There are also potential real economic values to such a concept: covering a roof with grass or a mix of flowers and grass can serve as natural insulation. It can prevent the breaking down of a standard roof membrane through prolonged exposure to the sunlight and serve as an acoustic barrier to dampen noise.

There are also psychological and aesthetic considerations mentioned which can be achieved through the use of a green roof. But perhaps the greatest benefit comes in tempering the rainfall runoff, the web site suggests.

While the most exotic, the green roof proposal is by no means the only suggestion from the council about how Lowe's - and the town - can minimize the impact of storm water runoff.

The review suggests reducing the number of required parking space and constructing a portion an outdoor display area of a "pervious material" rather than asphalt.

The report proposes that the runoff from the parking lot "will be collected in catch basins or a vegetated swale," while roof runoff will be directed into an underground system that will overflow into Cole Brook."

The council said its recommendations are "intended to help minimize potential adverse impacts such as sedimentation due to uncontrolled soil erosion, the degradation of downstream receiving areas by non-point pollution courses such as road deicers, fertilizers, pesticides and heat/thermal changes," as well as "the loss of stability or function of wetland systems."

The report is intended as an advisory document to assist the town's land-use commissions in their analysis of the plan.

Flourescent bulbs may become the new standard by law

A report in the March 26 N&O pushes the idea of replacing old style incandescent bulbs with new efficient fluorescent ones and discusses a new House bill North Carolina is considering that would eliminate the sale of old style bulbs by year 2016. The article also states "The U.S. Environmental Protection Agency estimates that the fluorescent bulbs use two-thirds the energy of incandescents and last up to 10 times longer."

Lawmakers put energy into limits on light bulbs

When Rep. Pricey Harrison saw Al Gore's Oscar-winning documentary "An Inconvenient Truth," a light bulb went on over her head.

It wasn't an incandescent bulb, but a fluorescent.

At the end of the movie, a list of tips on cutting carbon emissions includes switching to the new compact energy-efficient bulbs at home.

Harrison, a Greensboro Democrat, did that. Now she wants to go one step further, and eliminate incandescent bulbs around the state within a decade. Read more...

Fuel from fat

A North Carolina State University professor is working to develop a process to make high-grade fuel from remnants of animal fat. The current procedure is extremely slow - the first months of work has produced about a teaspoonful of the product. Now the work turns to making another two cups of fuel over eight months to power a small engine and prove the concept.

The work has attracted enough attention to get funding to carry the project another step forward and then work on ways to make the process practical for real production. "This is going to be competitive with today's prices for jet fuel, which runs about $2 a gallon," Jeff Hassannia said. "More importantly, it represents a domestic source of fuel at a stable rate that comes from a renewable input.""

Turning potatoes, grass into ethanol
NCSU gets $1.5 million for test plant

Researchers at N.C. State University already know they can make ethanol from sweet potatoes and switchgrass.

They don't know if they can do it day after day in quantities more meaningful than a lab beaker.

A $1.5 million grant, announced Wednesday by the Golden LEAF Foundation, could help them figure it out.

NCSU will use the money to build a pilot plant capable of making ethanol from products commonly found in the state, such as loblolly pine, sweet potatoes and switchgrass -- a tall, dense grass often used as field cover. Read more...

Build a green pc...

Your PC contributes to global warming and to a degree (no pun intended) helps run up your electric bill. An article from PC Magazine compares energy requirements of several home appliances including your PC and monitor.

One way to help address the issue is to buy a new PC that was manufactured with "green" concepts in mind. Another is to build your own green pc. How to do this is described in this article...

Global warming is caused by emissions of carbon dioxide, which trap heat so it can't escape the atmosphere. Although cars, factories and power plants do most of the damage, the computer is at least partly to blame. A PC uses 200 to 400 watts, depending on its configuration and use. By comparison, a refrigerator uses about 725 watts, but a DVD player uses only 25 watts, and your TV is right around 100 watts. A high-performance gaming rig with a powerful graphics card, multiple hard drives and optical drives, a flash memory reader, and a 30-inch LCD might consume as much as 750 watts! Leave such a beast running constantly and you might see an extra $40 to $50 on your monthly electrical bill. Ouch.

Yet PC energy consumption is only part of the problem. The manufacturing process for computer parts also has an effect. The typical computer these days contains significant amounts of lead, which is used in soldering motherboards, processors, and other parts. Since the average lifespan of a PC is just three years—according to the EPA—the toxic effects of disposal are quite high. Read more...
