The City of Gatlinburg’s commitment to convert the Gatlinburg Winter Magic Celebration lights program to 100 percent LED bulbs during 2008 has paid off in immediate and significant savings of electricity (not to mention reducing the City’s carbon dioxide emissions). LED lights use as much as 75 percent less energy, last ten times longer, produce (i.e., waste) almost no heat, and are more durable than glass bulbs. The City — like millions of Americans — have discovered that going green with LED lighting saves green and helps preserve the environment.  As I write about in ECOpreneuring, the “greentech” or clean tech sector, of which LED lighting is but one such technology, is booming.

A new Kansas-based company called EcoFit Lighting believes it can make the transition to LED street lighting not only much easier, but also much cheaper.

EcoFit’s design is a retrofit module that slides right into place in existing streetlights, eliminating the need to have a full replacement. The company claims using their product would bring down costs from $700 to $900 (for a complete replacement) to just $400. Savings also come in the form of energy efficiency and extended lifespan as EcoFit’s LED lights are 60 percent more efficient and last six times longer than sodium streetlights. Additionally, as it’s estimated that replacing street lights with EcoFit LED lights would take just five minutes (as opposed to taking up to 30 minutes to fully replace the head), labor costs are also expected to be reduced.

Ettenson told me that the funding comes from the part of the budget that California’s regulated utilities may use to invest in conventional electricity. This may include “negawatts”or energy efficiency measures. This is not just cheaper than building new plants and transmission, but also easier to implement, as it is not subject to the NIMBYism and transmission issues that has impeded development of utility scale solar and wind projects that California utilities must add to meet RPS requirements of getting 20% of its energy from carbon-free sources by 2010. Currently it is at 14%.

This giant leap in funding could jump-start the new low-carbon economy in California; helping grow all the businesses that create cutting edge efficiency in cooling and heating, lighting, building materials, windows, insulation, appliances and smart grid technologies that reduce energy use.

Ettenson gave me some examples of uses for the funding in practical terms:

Senator Sherrod Brown (D-OH) is proposing a bill that would lend $30 billion dollars to American small and medium sized manufacturing companies who specialize in clean technology.  The bill would make American manufacturers a player in the clean technology market which faces stiff overseas competition.  It is estimated that 70% of the components for clean technology (much of which was invented in America) are made abroad.  So far, 150 businesses have come out and endorsed the Senator’s legislation.

Nothing is ever black and white, or all bad without traces of good.  The world is full of grey areas, and electronics also create positive change. 

When driving to an new destination the other day, I noticed that I used much less gas because of my GPS than I normally would.  In the old days before Google maps and GPS technology, I used to get lost at least once, call on my cell phone or stop at the gas station to get directions, and generally take more time and fuel than necessary. 

Some will say this is just spatial ineptness - but I am willing to bet that others have had this problem too!

After a year-long demonstration project, the U.S. Navy is poised add its own contribution to reducing the military’s carbon bootprint - or carbon wake, as the case may be.  The Navy stands to gain up to 87% in savings for shipboard lighting, by switching from conventional light bulbs to high efficiency LED and HID systems developed through DARPA under the HEDLight (High Efficiency Distributed Lighting) program.  One recent retrofit has been accomplished by Ohio-based Energy Focus, Inc. Saving energy is just part of the picture: the quantum leap to HEDLight is also expected to yield significant gains in the Navy’s strategic efficiency.

Yes… most of the products marketed on television border on useless crap.  They’re symbols of conspicuous consumption.  The sales pitch feels cheesy. And, yet, as I mentioned in Five Greenish Products You’ve Seen on TV, a small handful of them appeal to values we promote here at sustainablog: conservation, re-use, and efficiency.

I’ve come across a few more that strike me not only as appealing to these values (and perhaps a few others that are positive), but also as a great way to spread sustainable practices… even if they’re not necessarily labeled that way.  Again, I don’t know the lifecycles of these products.  I assume most of them are made in China. I wouldn’t call any of them “green,” or endorse them outright (or try to sell them through affiliate links here).  But they’re definitely “greenish”… and if direct marketers are selling products by appealing to some of the values mentioned above, that’s an ever-so-small step forward. Here we go…

The city of Los Angeles intends to retrofit 140,000 streetlights with LED light bulbs. If successful, this will be the nation’s largest lighting retrofit, and it comes with a price tag of about $57 million.

With nearly 35 million streetlights in the United States, it’s estimated that they use 1% of all the electricity is consumed nationwide.

The initiative was announced in Los Angeles by former President Bill Clinton and Mayor Antonio Villaraigosa. That’s because LA is getting help with the retrofit from the Clinton Climate Initiative’s Outdoor Lighting Program. Part of the funding also comes from a $14 million rebate from the Department of Water and Power. The Clinton Climate Initiative has become an increasingly active arm of the Clinton Global Initiative.

“If you have ever been to Death Valley National Park and looked up on a clear night, you would see that the stars seem to be dimmer than they were when I was a child. But they are not getting dimmer, really–the rest of the sky is getting brighter because of all the lights from Los Angeles and Las Vegas and other surrounding cities and communities,” President Clinton said.

“This is the best place in the world — in the U.S. at least — to lead this,” Clinton went on to say, citing the city’s ongoing environmental efforts. “This is like taking 6,000 cars off the road. “If every major city followed your lead, we could eliminate 2 1/2 coal-fired power plants.”

Once the overhaul is complete, the city will get an energy savings of about 40-percent and reduce carbon emissions by 40 tons/year. It is expected this will save the city $48 million, and reduce carbon emissions by 197,000 tons, over a seven year period.

The program is scheduled to start in June. Initially 20,000 bulbs will be replaced, and 30,000 with each following year.

While the program will start before New York City’s own efforts to provide LED streetlights, but NYC hopes to replace up to 300,000 streetlights with LEDs. Oh snap!

While it seems odd to introduce this development on a sports car that boasts an energy-inefficient ten cylinder engine capable of propelling the car to 196 miles an hour, the reason is probably cost.

Autobloggreen.com notes that LED headlamps were available as a $5,600 option on the original R8. The R8 V10, to be sold in Germany beginning in the spring of 2009, will cost nearly $200,000.

Still, the technology that Audi has developed to show off on its most high-end vehicle, will eventually trickle down to other vehicles and other manufacturers, and every conceivable increase in efficiency should be welcomed as we move toward electric vehicles.

Audi estimates that a vehicle running with soon-to-be-mandated (in Europe) daytime running lights consumes a constant 200 watts (this includes low beams, tail lights, and a license plate light. In contrast, Audi claims that only 15 watts is required to power their daytime headlamps.
