Ladies and gentleman, boys and girls… come right in for another edition of the Greenest Show on the Web: the Carnival of the Green! Fresh off of a stellar performance at Ms. Malaprop, the Carnival’s here at Green Options this week to amaze and delight you. But don’t wait around — the show has a limited engagement here, and then it’s moving on for a stint with our friends at Greener Magazine.

What’s the Carnival of the Green (or COTG, as we green bloggers like to call it)? It’s a roundup of some of the best posts on green blogs from the past week. Always moving, the COTG stops for a visit on a green blog every Monday. The Carnival was the brainchild of Al Tepper, publisher extraordinaire at City Hippy, and Nick Aster, the man behind (and often in front) of the curtain at Triplepundit. These days, our friends at Treehugger play tour manager for the Carnival.

Now that we’ve got the formalities out of the way, let’s get on with the show. And if you’re suffering from a case of the Mondays, here’s a little music to put you in that carnival mood…. wherever you are.

The Hall of Science

Come on in, and take a gander at the latest technological wonders. Won’t cost you a dime…

We’ve got a double-header from EcoGeek this week. Want some help adjusting your driving to save fuel? Hank and co. take a look at the Fuel Mizer, which can monitor your stops and starts for you. And if you’re a walker (which we hope you are!), two students at MIT are just won a prize to harvest the energy from your footsteps (yep, we covered that one, too).

The Naib, over at The Sietch, investigates the Watercone, a device that uses solar energy to desalinate water. This piece of simple technology could do a lot of good for people without easy access to fresh water.

For the Dedicated Followers of Fashion…

We’ve got some Fall previews, and some new looks.

The Natural Collection is predicting an ethical Autumn as they roll out their Fall fashions online. Keep an eye on their site, as they promise "some fantastic giveaways, competitions and freebies" are on the way.

Nature Mom Tiffany Washko takes a look at some furnishings (particularly beds) that are both green and stylish.

Inhabitat shows us how designer Stephan Boltz gives a second life (and new sense of style) to airplane trolleys.

And speaking of reuse, our own Victoria E. shows us how the Broken Plate Pendant Co. turns "useless" china into unique pieces of jewelry (on her own blog).

The Carnival’s Trade Show

Catch the latest trends in green business and finance.

Sox First has a podcast interview with Erik Mather, managing director of Regnan, on the growing pressure for companies "…to come clean on their contingent liabilities that include environmental, sustainability and governance risks."

Great Green Gadgets expresses some skepticism about carbon offsets, particularly those involving tree planting. Doesn’t mean they’re against planting trees, though… even guerrilla style!

And the Savvy Vegetarian shares a post from market gardener Jocelyn Engman on the importance of supporting local farmers.

Time for a Break… and a Beer

All this carnivaling can make you thirsty…

GO’s Gavin Hudson shares some tips on making your own eco-friendly brew: cheers!

And the Green Cougar points to that inevitable post-college dilemma for green grads: aluminum cans or glass bottles?

The Medicine Show

Health and safety stories with a green tint.

Allie’s Answers takes note of some of the potential dangers presented by manufactured nanoparticles in sunscreens.

The Environmental Working Group’s Enviroblog presents a video on the danger that still exist from arsenic-treated lumber used for decks and playsets.

Finally, at sustainablog (my other blog), I took a look at an editorial in the Minneapolis-St. Paul Star-Tribune claiming that greener development of transportation infrastructure could create less wear and tear on roads and bridges (so they’re less likely collapse!).

Get a Glimpse of Far-Away Lands…

A couple of our participants in the Carnival this week share some travel information and experiences.

Intelligent Travel spotlights several green hotels you might want to consider on your next getaway.

The Souvenir Stand

If you must buy, make sure it’s sustainable.

The Millionaire Mommy Next Door claims that "Memories are made of the things we do, not the things we buy." We couldn’t agree more!

La Marguerite reminices on times past when we didn’t throw away so much stuff.

And Green LA Girl takes a look at some eco-friendly claims made by some companies about their products, and shows that a little digging often chips the green gilding off of these fairly ordinary items.

Finally, Take a Stroll Down the Midway…

You never know what you may find.

INNside Innkeeping in Montana highlights efforts by Xanterra Parks and Resorts, the owner of hotels and restaurants inside a number of state and national parks, to green up their own operations. That’s right… Yellowstone is going green…

In this week’s content swap with Naturalpath, we’ve added another article to the Green Life Guide: "Low Energy Light Bulbs: What’s the Deal?" The Naturalpath team has put together an informative Q&A on the issues surrounding compact fluorescent light bulbs that includes answers on the fixtures in which they can be used, the amount of energy you can save with these bulbs, the mercury question, and their strange shape. If you’re not using CFLs in your home lighting fixtures, you’re missing out on an easy, inexpensive and, yes, harmless way to cut your electric bill.

As always, we’re grateful to Naturalpath for sharing their content with us. Don’t forget to look and see which of our blogs posts the NP team has chosen to feature on their site.

And, if you were looking for the second part of NP interview with the authors of Skinny Bitch, you can find it here.

Editor’s note: I started working on this post yesterday, and after writing and writing and writing, I realized it was turning into a David post While I heard a lot of interesting discussion yesterday, I’ll try to stick to an overview of main ideas and questions, and then respond to your comments and questions. Perhaps we can extend the symposium into our own space here…

This morning, I got to attend my first major session at the Papandreou Foundation’s Symi Symposium. Entitled "Energy in Flux: Safe Passage to a Future of Alternatives," the session consisted of three presentations on transitioning to a new energy future, and a lively debate over the challenges and opportunities created by the need to shift energy priorities in the face of global climate change.

Overall, I was delighted by the optimistic tone that ran throughout these presentations (which, in some cases, became points of contention in later open discussion): all three speakers acknowledged the enormity of the environmental challenges we face, and noted that combined efforts of the public and private sectors will be necessary to mobilize the larger public to action. In each presentation, the speaker focused on public involvement (in the roles of consumers and citizens), and made the case that an educated populace will provide the momentum for adoption of clean, renewable energy options. Let me just give a very brief overview of the main points offered by each speaker.

The first presentation focused on consumers’ roles in transitioning to a low-carbon energy infrastructure. Dr. Joseph Stanislaw noted that, traditionally, when we talk about energy, we talk about supply: where does it come from? He argued that a shift in mindset and language towards the services energy provides creates greater opportunity for transitioning towards more sustainable energy options. Consumers don’t want energy created from coal, or from solar power, for that matter: they want the services that reliable energy provides. By focusing on meeting this demand, we can address our contributions to climate change by implementing currently available technologies (particularly conservation technologies) while also working on the next generation of cleantech solutions. Consumers can be empowered to contribute to lower consumption by educating them on the "low hanging fruit" available: CFLs, for example. Finally, Stanislaw noted that the private sector is well ahead of the (US) government in recognizing these opportunities: he specifically discussed Wal-Mart’s sustainability efforts.

The second and third presentations both focused on engaging populations as citizens in transitioning towards cleaner energy technologies. The first, presented by James Fishkin of Stanford University of the two described experiments conducted by Texas utilities in "deliberative democracy": representative groups of customers were brought together in person, and through television, to discuss opportunities to purchase "green" power through their utilities. The sessions served to both educate the people gathered, and to listen to their concerns. These sessions produced amazing results: before these sessions, 52% of these consumers will willing to pay more for green energy; afterwards, 84% expressed willingness. The speaker noted the the increased prices don’t have to be much larger: even a $.25 addition to customers’ monthly bills would generate millions of dollars for increased renewable infrastructures. The success of the Texas experiment has led to other requests to hold such events: they’ve been repeated in Nebraska and Nova Scotia (with similar positive outcomes), and more will be held in Vermont, and as part of the next National Governor’s Association meeting. The third speaker, John Panarenos, provided the results of a similar effort in Europe: when asked, the representative samplingof citizens choose "energy and environment" as the most pressing issues facing the EU. The combination of terms was important — when the word "environment" was presented by itself, it didn’t receive nearly as high numbers.

As you might imagine, other symposium delegates had plenty of questions and even challenges for these speakers. A few points offered:

• The "small steps" position of the first presentation was challenged with the Chinese proverb "You can’t cross a ravine with small steps": ultimately, the enormity of these problems require much bigger responses.
• The market focus (which was not exclusive — he wasn’t arguing for "letting the market fix the problems") of the first speaker’s presentation was also questioned, with at least one respondent noting that we must focus on what scientists say is necessary, rather than what is possible in a consumer market.
• Several respondents also argued for more top-down regulation — in fact, that seemed to be a major point of debate: a focus on grassroots action (which is what I heard coming from these presentations) vs. government regulation.

Needless to say, this session was fascinating and provocative: as the first speaker noted, we can’t separate energy issues from climate change, so these kinds of discussions are necessary. I’ve just given the briefest of overviews here — feel free to offer comments or ask questions…

The evening sessions at the symposium are shorter and a bit less formal. Tuesday’s evening’s focused on a presentation by Kim Alter (Oxford University) on the concept of social entrepreneurship and social enterprise: the hybridizing of business and non-profit models into a unique endeavor that harnesses market forces in innovative ways to address social (and environmental) challenges. As with the morning session, the discussion was lively following the presentation. The concept of social enterprise as a distinct category, rather than another form of non-profit, was a major question for participants in the discussion.

Tomorrow: Excursion day…. with lots of photos from Paros and Antiparos….

OBI President Bill Horan demonstrates a solar ovenMost of us in the developed world don't think a lot about the source of fuel we use for cooking: unless there's a power outage, we can turn a knob or press a button, and we've got the heat we need. If we've got a gas stovetop, we don't even need the electricity! We know, of course, that people in the developing world generally aren't this fortunate, and wood-gathering is a necessary part of the food preparation ritual. But what do people in poverty do if wood supplies start to run low because of deforestation, desertification, or just a simple lack of usable wood?

In Gansu, China, a region that receives little rainfall and has no trees, a very old technology has provided a solution: the solar oven. The concept of using a curved mirror to focus sunlight, and the heat it provides, has been around since the ancient Greeks; relief and development agency Operation Blessing International has purchased and installed over 200 of these ovens (made from concrete and mirrors) in Gansu. The program has been so popular that the organization has just released funding for 200 more in the region. According to Operation Blessing president Bill Horan,

"In Gansu, like in many other poverty-stricken regions around the world, firewood is as precious as water. There are virtually no trees here, and so little rain, that the only bath most people take in their whole life is on their wedding day. These solar ovens are based on ancient technology and they are eco-friendly - a totally renewable energy source."

OBI is considering taking the program to another devastated region of the world: the Darfur region of the Sudan, where the organization operates several refugee and relief camps in partnership with a German charity.

We Westerners tend to associate "technology" with the latest devices: computers, cell phones, renewable energy installations, etc. This simple, time-tested technology, though, looks like just the thing for impoverished people around the world. And, even with the high carbon emissions associated with concrete production, this looks like a pretty climate-friendly alternative, too…

As regular readers of GO know, the world of green technology is moving forward at a blinding pace. Every week (shoot, sometimes every day) brings many exciting stories about breakthroughs and developments, ranging from more efficient ways to light your home to next-generation renewable energy solutions that can power whole communities. It's both challenging and exhilarating to try to keep up with the latest news.

Of course, those of us who aren't designers, engineers or scientists likely come up with questions (perhaps many of them) about these developments. Why does a CFL use less electricity to produce light? Which is the best long-term solution for personal transportation: hydrogen or batteries? And, just how do solar panels turn sunlight into electricity? You're certainly not alone if you're asking these questions…

In order to give you a place to ask about green tech, we've partnered with EcoGeek.org to create "Ask the EcoGeek," a weekly column that will answer some of these questions. Each week, Head EcoGeek Hank Green will choose a question submitted by a reader from Green Options, EcoGeek.org, or another participating site to answer in the column.

Got a question that you think might be appropriate for Hank? Just use the submission form we've created to ask it. Hank's working on his first column (already got some questions from EcoGeek readers)… look for it regularly on Thursdays.
