The US Department of Energy (DOE) has released an update of its report that forecasts the energy-savings potential of solid-state lighting (SSL) compared with conventional white-light sources. The 2012 update entitled "Energy Savings Potential of Solid-State Lighting in General Illumination Application," compares the annual lighting energy consumption in the US with and without market penetration of LED lighting beyond current levels.
The cumulative energy-savings potential from the predicted LED market penetration over the 2010-2030 study period is 2700 TWh, a savings of $250 billion at today's energy prices or the equivalent of 1800 million metric tons of carbon. This is in comparison to the 1800 TWh of savings estimated in the 2010 report of energy-savings potential. However, several significant changes were made to the study's methodology and assumptions for the latest report, which are discussed below.
The forecast predicts that by 2020, LED lamps and luminaires will have primarily penetrated the commercial and outdoor stationary applications. Proliferation into residential, industrial, commercial and outdoor stationary markets will occur in the 2020-2030 timeframe.
The forecast projects LED lamp and luminaire sales measured in lumen-hours. The analysis indicates that LED lighting in general illumination applications has the potential to represent 36% of sales measured in lumen-hours on the general illumination market by 2020 and 74% of sales by 2030.
According to the Energy Information Administration (EIA), the US consumed 694 TWh of site electricity in 2010 on lighting - approximately 18% of all electricity used. The model demonstrates the total energy consumption for lighting could be reduced by 19% by 2020 and by 46% by 2030 relative to a scenario with no additional LED lamps or luminaires beyond what is installed today.
By 2030, the annual energy savings from market penetration of LEDs will be approximately 297 TWh, enough electricity to power 24 million homes. At current energy prices, that equates to $30 billion in savings in the year 2030. Assuming the same mix of power stations, these savings, according to the report, would reduce greenhouse gas emissions by 210 million metric tons of carbon in 2030.
The DOE has published this report four times, in 2001, 2003, 2006 and 2010. Several important changes to the 2010 methodology have been implemented. First, the 2010 baseline data now uses the DOE's recently published 2010 US Lighting Market Characterization inventory report. That report showed that 67 million LED lamps and luminaires were installed in the US in 2010, accounting for 0.8% of the total.
Secondly, the energy-savings report only considers LED technology and not OLEDs, due to the speculative nature of efficacy projections and price forecasts for OLED luminaires. All energy savings are assumed to be due to LED technology and its improvements.
The model includes lighting in residential, commercial, industrial and outdoor stationary applications. The previous reports then grouped lamps by high- and low-CRI application. Now the lamps are grouped by submarket in which different technologies compete, including five categories: general service lamps (medium screw base), reflector lamps (screw base), HID, linear fluorescent and miscellaneous.

Odyne Systems Delivers Plug-In Hybrid Propulsion Systems
Odyne Systems has delivered seven trucks featuring the Odyne advanced plug-in hybrid propulsion system to utilities and municipalities throughout Wisconsin, and also has delivered the first digger derrick featuring the system to Commonwealth Edison Company, one of the largest utilities in the United States.
Communities and utilities receiving the new technology were partially funded under the Wisconsin Clean Transportation Program jointly administered through the Wisconsin State Energy Office and the U.S. Department of Energy Wisconsin Clean Cities Program. The new units are anticipated to deliver fuel efficiency over a conventional truck of up to 50% annually, depending upon the use of the truck.
"The implementation of this technology in the Wisconsin Clean Transportation Program has resulted in efforts not only to reduce our nation's dependence on petroleum, but to additionally improve air quality and develop statewide economic opportunities," said Lorrie Lisek, Executive Director of Wisconsin Clean Cities Southeast Area, Inc.
The hybrid digger derrick was funded in part by a $4 million award ComEd received in federal economic stimulus funding to expand its alternative-fuel fleet. ComEd received a $1.5 million grant from the City of Chicago that stems from $15 million in American Recovery and Reinvestment Act (ARRA) funding awarded to the city by the U.S. Department of Energy (DOE) under its Clean Cities Grant program.
"Diesel vehicles and equipment are significant contributors to air pollution and greenhouse gas emission in Chicago. By adopting innovative vehicle technologies, such as ComEd's new hybrid truck, we can improve the health of our residents and save money on fuel costs," the City of Chicago's Chief Sustainability Officer Karen Weigert said.
Odyne's proprietary and patented hybrid technology combines reliable electric power conversion, power control and energy storage technology with Remy advanced electric propulsion motors, modular Johnson Controls lithium-ion battery systems and other robust, automotive quality components.
The Odyne plug-in hybrid drive system reduces fleet operating and maintenance costs, and depending on duty cycle, enables large trucks to obtain significant fuel economy improvements compared to traditional diesel engines. The Odyne advanced hybrid system also lowers emissions and provides a quiet, safe working environment with good work site communication, setting the new benchmark for the hybrid work truck industry.
Milwaukee County took delivery of four work trucks in December 2011 and January 2012 that will be used throughout Milwaukee County to maintain traffic signals and street lighting. Although the county automotive fleet includes hybrids, these are the first hybrid trucks they are putting to work.
Manufactured by DUECO, Inc. the vehicles feature the first Odyne hybrid systems installed on Kenworth truck chassis and are the first to power Venturo corner mount cranes, which will be used in sign maintenance and to lift lighting as the county switches to more efficient LED lighting. The trucks feature fiberglass bodies and Terex TL60 aerial buckets, recognized for their stability.

San Juan golf-range lights get go-ahead
San Juan Hills Golf Club will be able to install lights for its driving range after all, now that the San Juan Capistrano City Council has voted unanimously to overturn the Planning Commission's denial of the proposal.
The council voted Tuesday to overturn the commission, which had voted 3-2 on Nov. 22 to deny the club's request for a conditional use permit, citing concerns about adverse effects on adjacent residences because of the lights and added noise from nighttime use of the range at 32120 San Juan Creek Road.
The city received 44 letters about the issue, 38 of them in support of overturning the commission's decision and six in favor of the commission. City staff had recommended that the council overturn the denial, saying the proposal is consistent with the community design element of the city General Plan and that the lights would not be bright enough to seriously affect nearby residents.
Under the plan, the driving range is to feature outdoor lights installed on existing 50-foot poles and three new 25-foot poles.
Representatives of the golf club said the lighting would have minimal effect on the surrounding area, describing the system as the first of its kind.
Karin Pekala of Musco Sports Lighting, a consultant for the golf course, said the design of the lights will significantly reduce light pollution. She said the course agreed to drop the foot-candle measurement (of luminance) to five from the standard 10.
Pekala said the light emitted from the range would be comparable to the light from a full moon. She said the course will be one of the first to use special visors on its lights to shield the community from glare.
Some residents were skeptical, however, calling on the council to test the lights before giving the club a permit for the installation.
Others questioned the validity of the claim that trees surrounding the range would provide adequate cover from the light. San Juan resident Mark Nielsen said the golf course's estimate of 85 percent tree cover around the range is too high, saying it is closer to 60 percent.
San Juan Hills Golf Club management said it plants new trees frequently and is not opposed to planting more trees and shrubs in conjunction with the new lights.
The council also agreed to let the course keep the driving-range lights on until 10 p.m., as proposed. City staff had recommended a 9 p.m. shutoff to try to reduce noise from nighttime use.
"This will improve the recreation quality of San Juan Capistrano ... and it boosts the economic engine of the city," Councilman Sam Allevato said.
Councilman Derek Reeve said he is concerned about the surrounding community, but "the benefit outweighs the cost."
Staff said the city has the capability of testing the foot-candle measurement, and the council directed it to do so once the lights are up.
Among the biggest supporters of the lights is the San Juan Hills High School golf team, whose coach, Jim Tinker, said the lighting and increased student access to the driving range will help support and improve his team, which won a CIF division championship last year.

US promotes democracy with suddenly important Togo
After venturing to reclusive Myanmar, Secretary of State Hillary Rodham Clinton pressed democratic reforms Tuesday in another place long dominated by dictators, becoming the first American in her post to ever visit the African nation of Togo.
Greeted by performers on stilts and sword-wielding ceremonial soldiers in red capes, Clinton visited Togolese President Faure Gnassingbe in his presidential palace, a Chinese-built construction of marble floors and sparkling Christmas-like lights strung from the ceiling. Paintings sat against the walls, the unfinished work of a hasty decoration.
The decadence on display, just beyond the destitute streets of Togo's capital, Lome, in some ways evoked the worst of post-colonial Africa and its rulers' all-too-common penchant for ceremonies and ornamentation while their people languish in poverty. Yet after six decades of dictatorship, Togo is showing signs of progress — much like Myanmar, or Burma, before Clinton's trip last year — and the Obama administration wanted to take a chance.
"Togo's national elections later this year will be an important milestone," Clinton said. "The United States will be a partner to the government of Togo as it builds on its recent democratic gains, brings dissenting voices to the table for an inclusive dialogue, increases the political participation of women, and carries out a successful constitutional reform process."
The choice of Togo isn't solely about goodwill. The West African country of 6.8 million people, tucked between Benin and Ghana, is as of two weeks ago a U.N. Security Council member. That means it may vote alongside the world's biggest powers on resolutions that could cover anything from a future Palestinian state to sanctions against Syria.
Clinton and Gnassingbe agreed to cooperate on both issues, a senior administration official said, speaking on condition of anonymity because the meeting was private. Gnassingbe backed U.S. support for direct Israeli-Palestinian talks and opposition to a premature Palestinian declaration of statehood, the official said.
Clinton visited Togo on the penultimate stop of a four-country Africa swing aimed at encouraging governments to continue with democratic and economic reforms.
She led a U.S. delegation Monday to the inauguration of Liberian President Ellen Johnson Sirleaf, Africa's first female head of state. She then traveled to Ivory Coast to meet the democratically elected President Alassane Ouattara, who took office last year after his forces finally ousted predecessor Laurent Gbagbo, who had refused to cede power. She will stop in Cape Verde before returning to Washington early Wednesday.
The trip to Togo was the most unexpected. Whereas Washington has championed the ascents of Sirleaf and Ouattara, respected economists with resumes that include the World Bank and International Monetary Fund, the U.S. has largely ignored Togo since it gained independence from France 62 years ago.
Details of Clinton's meeting with Gnassingbe showed an attempt to U.S. interests with a new partner, along with encouragement for democracy work in Togo that still has a long way to go.
Washington is optimistic about Gnassingbe despite his history as the military-pronounced successor of his father, a dictator who crushed opponents for almost four decades. He won a flawed election seven years ago and was re-elected in 2010 in a vote that edged closer toward constituting a free and fair multiparty contest.

High school student intern at UAlbany Nanocollege is selected as semifinalst in Intel science competition
A high school senior conducting innovative nanotechnology research as part of an internship at the College of Nanoscale Science and Engineering of the University at Albany has been selected as a semifinalist in the 2012 Intel Science Talent Search, the nation's most prestigious pre-college science competition.
Seyoon Lee, a senior at the Berkshire School in Sheffield, Massachusetts, is among just 300 students chosen nationwide from 1,839 entrants – the most the competition has seen in over a decade. On January 25, 40 of the 300 semifinalists will be named as finalists, and will compete for more than $1.25 million in awards provided by the Intel Foundation.
Working with F. Shadi Shahedipour-Sandvik, CNSE Associate Professor of Nanoengineering, Lee is conducting research at CNSE on the development of a new type of white light emitting diode (LED) based on a hybrid semiconductor device that uses both organic and inorganic materials. By altering the inorganic layer, he was able to increase the intensity of white light being emitted, which could advance the current progress for implementation of energy-efficient and environmentally friendly solid-state lighting, as compared to today's incandescent light bulbs.
Captain of Berkshire School's math team, which ranks first in New England for schools with 500 or fewer students, Lee began working with Professor Shahedipour-Sandvik at CNSE as a 10th grader in 2010.
"I am thrilled to congratulate Seyoon Lee on his selection as a semifinalist in the Intel Science Talent Search. He is very well deserving of this recognition, especially given his dedication for the past three years to our highly technical research in the important area of clean energy," said Dr. Shahedipour-Sandvik.
"This prestigious honor truly defines him as one of our nation's best and brightest young scientific minds, while further demonstrating the ongoing commitment of the UAlbany NanoCollege to serve as a world-class educational hub and training ground for the innovators of the 21st century."
"It was by far the hardest thing I've ever done in my life," said Seyoon Lee. "I was very lucky to receive guidance and advice from my mentor Dr. Shadi and other graduate students, especially Puneet Suvarna. I also want to thank Dr. Geer and CNSE for giving me the chance to do scientific research. The gravity and professionalism of the process of entering INTEL and writing a scientific paper were valuable experiences that will help me throughout my future. I am grateful to Mr. Schleunes and Berkshire School for giving me such an amazing opportunity that I couldn't even dream of having if I had stayed in Korea."
Now in its 14th year, the Intel STS encourages students to tackle challenging scientific questions and develop the skills to solve the problems of tomorrow. Projects submitted for consideration cover all disciplines of science, including biochemistry, chemistry, physics, mathematics, engineering, behavioral science, and medicine and health. Past participants have received some of the world's most prestigious honors, winning seven Nobel Prizes, two Fields Medals, three National Medals of Science, and 11 MacArthur Foundation Fellowships.

Next-generation light bulb shines at CES
Switch Lighting executives Tracy Bilbrough and Brett Sharenow glowed as they showed off new-generation LED (light-emitting diode) bulbs that they believe will transform the more than $30-billion global market.
"It is exciting to be the little David taking on the Goliath's of the world," Switch chief Bilbrough told AFP.
"You pick this because it doesn't have mercury; you can dim it; it loves cold weather; there is no ultra-violet so they don't draw any bugs outdoors, and it fits in any fixture an incandescent bulb goes in."
Switch bulbs being are being tested in two US hotels and will begin shipping later this month as a smart option to incandescent or CFL models.
Incandescent bulbs are power-sucking classics being phased out in countries around the world, replaced by energy-efficient CFL versions containing toxic mercury that make them hazardous to toss in the rubbish.
"LEDs are really the next thing in lighting," said Switch chief strategy officer Sharenow.
The Silicon Valley company's bulb is touted as Earth-friendly from "cradle to cradle" and lasts about seven times longer than CFLs while providing the kind of light people like from incandescent.
Switch bulbs have an artistic look akin to a snow glove perched on a silver pedestal. They can also survive a three-foot drop to a hardwood floor.
A ring of metal prongs, each with a computer chip on it to emit light, is immersed in liquid that fills each bulb. The liquid cools the chips while acting as a lens to magnify light.
"It is food-grade; actually used in making beer, pasta and women's cosmetics," Sharenow said of the liquid, the ingredients of which were secret.
"We actually get more light out of the LEDs with liquid in the glass dome than if there was air in there."
Switch bulbs use 80 percent less electricity than incandescent bulbs and last for about 25,000 hours no matter often you switch them on or off, he added.
Switch bulbs, which are being launched in 65- and 75-watt models, are priced at $35 each but the price was expected to drop under $20 by the end of the year.
Even at a price of $35, businesses recover the cost in six months while homeowners hit that mark in two years, according to Sharenow.
LED bulb efficiency is on par with CFL, which cost about three dollars each versus 50 cents for incandescent. Bilbrough expected LED bulbs to quickly get more efficient that CFL.
Switch is first targeting businesses that see cost-savings in energy-efficient bulbs that last them more than a decade. Bilbrough estimated that Switch bulbs would last about 25 years or longer in home use.
"If you put that in your baby's room when they come home from the hospital, they will still be studying under it when they are in college," Bilbrough said with a nod toward one of the bulbs.
"These things will last longer than your phone, iPad, car or sofa."
When people are done with Switch bulbs, the company wants them back so they can recycle or reuse the parts giving them new lives in a practice referred to in the industry as "cradle to cradle."
"We want to reuse every part we can so nothing goes back to the biosphere of the Earth," Sharenow said.

Home Depot is hosting workshops to teach you about energy-efficient lighting options
With the new year comes new ways to light your home. The incandescent light bulb is being phased out in order for our country to be more energy efficient.
"This year, it's 100 watts. Next year is 75 and two years from now is 60 watt and 40 watt light bulbs," says Dennis Terebecki, a lighting expert at Home Depot.
But he isn't just an expert. "I'm a believer. It works."
So what's the difference between compact fluorescent and LED light bulbs?
"The compact fluorescent bulb is the one that looks like a corkscrew. It is fluorescent, like you see in a standard building. They last 4 to 5 years. The down side is they contain mercury. The LEDs are a solid state technology. They last much longer, up to 25 years," says Terebecki.
These bulbs may cost you more, but Dennis says you'll save on your energy bill. If you need some convincing, Dennis did the math for you. On his own electric bill, the incandescent bulbs cost him $10 a year, using them about four hours a day. The LED bulbs cost him $1.33.
"I started with one bulb. It was a bulb I used for reading and as soon as I came to see that one was really that much better, I changed the whole house," says Terebecki.
There are more than 100 bulbs to choose from on the shelves at Home Depot. So to help you out, through the month of January, Dennis and other experts at area Home Depots will host how-to workshops to educate you on the benefits of newer bulbs and which suit your needs.
"I'm hoping that I can teach them what I found. The bulbs are better, they run very cool, they run very long, and they help your house," says Terebecki.
Home Depot and other retailers will carry incandescent bulbs until they are sold out.
The workshops are every Saturday in January at 10:00 a.m. at all area Home Depot stores.

These bulbs may cost you more, but Dennis says you'll save on your energy bill. If you need some convincing, Dennis did the math for you. On his own electric bill, the incandescent bulbs cost him $10 a year, using them about four hours a day. The LED bulbs cost him $1.33.
"I started with one bulb. It was a bulb I used for reading and as soon as I came to see that one was really that much better, I changed the whole house," says Terebecki.
There are more than 100 bulbs to choose from on the shelves at Home Depot. So to help you out, through the month of January, Dennis and other experts at area Home Depots will host how-to workshops to educate you on the benefits of newer bulbs and which suit your needs.
"I'm hoping that I can teach them what I found. The bulbs are better, they run very cool, they run very long, and they help your house," says Terebecki.
Home Depot and other retailers will carry incandescent bulbs until they are sold out.
The workshops are every Saturday in January at 10:00 a.m. at all area Home Depot stores.

Book Highlights Failings of Enviro Trends
Todd Myers of the Washington Policy Center has advanced the cause of environmental protection by writing "Eco-Fads: How the Rise of Trendy Environmentalism is Harming the Environment." He lays out a logical case as to the causes and effects of the modern rush to embrace trendy eco-fads and does a good job of explaining how most of the fads do not deliver the promised environmental benefits (in many cases they actually do harm to the environment).
"Eco-Fads" is divided into two parts. The first deals with explaining what eco-fads are and why they are promoted by many politicians, some businesses and most of the media. The second exposes the rationale, or lack thereof, for embracing the fads and how their proponents convince others to adopt their favored policies.
As pointed out in the book, compact fluorescent light bulbs have become the poster child for eco-fads. The problem — CFLs save energy but can cause harm to the environment because they contain hazardous mercury gas. Myers points out that the hypocrisy of environmentalists is startling when one considers their support of CFLs coupled with their crusade to eliminate mercury emissions from coal-fired power plants, no matter what the cost to consumers.
Many environmentalists will find little to like in this book as the author uses rational thought and science to debunk many of their pet assumptions. "Eco-Fads" is a good read for the average consumer who wants to do the right thing for the environment but does not want to be taken advantage of by special interest groups or politicians with self-serving motives.
Lighting. Even though Tom Edison's incandescent light bulb won a nine-month reprieve from Congress last month, you may want to start the conversion anyway. Now-delayed efficiency rules were to require a phase-out of the old bulbs and a phase-in of more efficient bulbs such as compact fluorescent light bulbs or LED lights. Those more-efficient bulbs have a bit more expensive initial cost compared to a less-efficient light. But lower energy usage and a longer life from the new bulbs will make up for the higher purchase price.
Resolve this year to replace your incandescent light bulbs with CFLs or LEDs as they burn out, and start to save.
Heating water is the second-largest energy user in a home, so fix any dripping faucets. Otherwise, you're wasting water and the energy needed to heat it. After turning off electricity to the water heater at the service panel, set the water heater thermostats to 120 degrees. You might experiment by gradually reducing your water heater thermostat settings to find out what temperature works for you. Most have two thermostats, so be sure to set them both. Put insulation around your water pipes including the inlet and outlet piping above most water heaters.
Energy Star labeling. Buy appliances and electronics with the Energy Star label, which certifies that refrigerators use 15 percent less energy than their non-Energy Star peers, that dishwashers use 25 percent less, and clothes washers use 50 percent less. The orange Energy Forward sticker on TVs also indicates energy efficiency.

No rush for resolutions
Friends back home tell me the Christmas displays hit the shops as soon as the schools go back in September, and get into full swing by mid November when the z-list celebs are rolled out to turn on the Christmas lights in market towns everywhere. We were dumbfounded when flying via Lisbon airport in October to see two fully decorated Christmas trees in the international terminal. Having got over the shock of there also being three Harrods establishments in the small shopping and cafe area, we decided to blame the British influence for the premature decorations.
For me, the season really starts to get festive when Spain celebrates Constitution Day and the Immaculate Conception on 6th and 8th December. That's when I start planning my present list, mix the Christmas pudding and bake the Christmas cake so that it can be drowned in fed with brandy regularly up until it's iced nearer to the big day. Christmas 2012 is going to be very disorganised if Mr Rajoy suspends my beloved early December Christmas preparation days off work! He can have the rest of the bank holidays if only he'll just give me these two!
Before you know it, 25th December is rapidly approaching, at least one internet supplier has failed to deliver, you've run out of wrapping paper / sticky tape / gift tags (delete as appropriate) and the guilt is mounting as the Christmas cards continue to flood in despite the fact everyone knows WE NEVER SEND CARDS!
Christmas Day arrives and, in our household at least, presents are unwrapped, paper strewn everywhere, and a true festive feast is duly inhaled by humans and dogs alike and then…
… it's over. Isn't it?
I hanker back to those days working in England (not something I do very often) and long for the shut down week between Christmas and New Year when most office staff don't work because, after all, nothing gets done anyway. Christmas Day bleeds into Boxing Day and the sales drag us all hopping and skipping back to the shops, where we sneakily return those ghastly presents from great Auntie Maud.
We relax, bicker, argue and generally enjoy a break from work before partying on down with the rest of the New Year's Eve revellers and recovering the next day with another feast. No presents to foist upon each other but, instead, the important deliberations, decisions and declarations of our New Year's Resolutions to be made. Festive week over? It's back to work, full of our good intentions and enthusiasm after a good rest and ready to take on the world and a brand new year.
On the Costa del Sol it's back to work on Boxing Day so that clients can come in to pass on their Christmas greetings, use our internet and print off their boarding passes. Bizarrely not so many are interested in buying houses between Christmas and New Year. The phone stays silent, junk emails keep us entertained as there are no others to read and we wade our way through the gifted boxes of chocolates while gazing longingly out of the window at the British tourists enjoying their shut down week. Bah humbug!
New Year revelry is somewhat more sophisticated among the expats and holidaymakers here and New Year's Day passes similarly to a traditional Sunday with everywhere closed except for some hardworking restauranteurs and bar owners.

Five New Year's Resolutions For The Desert
It's that time of year when we're choked to the gills with lists of resolutions for the New Year, pinning our hopes to attain generally impractical goals to the more or less arbitrary beginning of the year.
And who am I to buck a trend? Here are some resolutions you can adopt that will help protect California's deserts. What distinguishes this list of resolutions from most others is that these are all either easy, or fun, or both.
California's deserts are ground zero in the U.S. for industrial solar energy development. Few dispute the need to stop burning coal to light our unsued closets and billboards: it's just sensible. But most new large desert solar plants are being built on the assumption that per capita energy use will continue to climb. In the rush to develop new sources of renewable energy, a major factor is almost always left out of the discussion: Americans waste an astonishing amount of energy. People in some European countries use half or a third the energy we do while enjoying similar, or better, standards of living.
Some 30 percent of annual U.S. energy consumption goes for lighting, and yet an astonishing number of us still use inefficient, century-old technology to illuminate our living spaces. The old-style incandescent bulb is going the way of the dinosaur, but there are a whole heck of a lot of the things still in circulation, often left burning in places that need light only sporadically.
A compact fluorescent bulb can provide the same amount of light for somewhere around a quarter the electricity. If you're concerned about the small amounts of mercury in compact fluorescents -- as well you might be -- the even more efficient LED bulb has dropped dramatically in price of late. At some point in 2012 you can expect to see an LED bulb as bright as a 60-watt incandescent bulb drop down below the $10 level -- about where compact fluorescents were a decade or so ago.
Even if you stick with incandescents for now, changing your outdoor lighting can make a huge difference. A significant amount of energy is wasted when we use outdoor fixtures that allow light to shine toward the sky. Slap a reflective hood on that thing, cut the wattage by about half, and you're doing your part to save energy while helping the stars shine a little brighter.
You've probably guessed the reason for this resolution: the desert is the preferred location for Southern California landfills. Activists defeated one giant proposed landfill next to Joshua Tree National Park this year, but L.A.'s trash now goes instead to the Mesquite Regional Landfill in Imperial County, a project bitterly opposed by environmental activists. As we reported last year, another large landfill is being proposed for the margins of Anza-Borrego Desert State Park.
Sensibly, the less trash we throw away the less will eventually end up in the desert. Angelenos are already pretty good at this compared to the average American: 65% of LA residents participate in curbside recycling programs. But there's a lot more to trash reduction than recycling. As the old adage has it: Reduce, Reuse, Recycle.
Reduce the amount of trash you generate by products with less packaging or that are more durable than their alternatives. You might even consider not buying that particular thing at all, thus eliminating its associated waste completely and saving you some cash.
Reuse by repairing minor breaks and flaws, with superglue or darning needles or -- for some real reuser cachet, duct tape. Or let someone else reuse your stuff by donating still-intact objects to thrift stores or giving it to someone you know who needs it.

DoJ's Internet Gaming Green Light to States is 'No Big Deal for Tribes
Cash-strapped states grappling with big budget deficits may welcome a Justice Department opinion that they can offer online lotteries and gaming, but tribes greeted the news with a virtual shrug of the shoulders, according to Indian gaming experts.
The Justice Department released a legal opinion stating that the 1961 Wire Act prohibits online betting only for sporting events and contests, not lotteries. The opinion has caused a flurry of interest in states looking to bolster revenues in the face of a projected collective budget gap of $31.1 billion in 2012, according to the National Conference of State Legislatures.
In Connecticut, for example, Malloy welcomed the Justice Department news. Malloy has talked about the need to increase state gaming revenue especially with shrinking revenues from the state's two signature Indian casinos – the Mashantucket Pequots' Foxwoods Resort Casino and the Mohegan Tribe's Mohegan Sun – and the prospect of competition from increased gaming in nearby Massachusetts and Rhode Island.
"Obviously, gaming is an important part of our economy. It appears that [online] interstate and intrastate gaming is going to be allowed," Malloy told the Hartford Courant. "It appears that the only thing the Justice Department has ruled is off the table is sports betting, with the exception of horse betting. So with that one exclusion, everything is up for consideration by the states."
Last year, Internet gaming reportedly generated more than $25 billion worldwide with $7 billion in wagers from U.S. bets on Internet sports, poker, and casino games with 10 million U.S. citizens playing poker online.
Melissa Riahei, general counsel of the online gaming firm U.S. Digital Gaming, told The Hill that the Justice Department "has finally confirmed what we believed in Illinois to be true all along—that intrastate gambling is an issue that is within the sole discretion of a state to regulate, as it deems appropriate." She said states can now "comfortably" begin to implement Internet gaming programs to generate revenue to fund "essential government services."
That won't be as easy or quick as Riahei implies, according to Indian gaming expert Joe Valandra. Before moving ahead, states have to pass legislation to allow Internet gaming and that may present some barriers, Valandra said.
"I don't think (the Justice Department opinion) is a big deal for the tribes because there's only one state that has enabling legislation and that's Nevada. Other states have talked about it, but haven't passed anything. It has to go through a whole legislative cycle before any state besides Nevada will be able to offer intra-state online poker."Valandra said.
A citizen of the Sicangu Lakota, Valandra is principal owner and president of VAdvisors, LLC, chairman and CEO of Tehan Woglake, Inc., and former chief of staff of the National Indian Gaming Commission. "It's something I'm sure the tribes in general are looking at but I don't think it has any particularly negative implication in and of itself."
