In Oregon, bicyclists want to roll through traffic-free stop signs

In the '70s, the right-on-red wave passed through the states as drivers were increasingly frustrated by idling at red lights devoid of cross traffic. When one is stopped at a red light on a timer, a right-on-red and the even more daring left-on-red -- permitted in Oregon in some situations -- make sense.

What makes even more sense is to let bicyclists treat stop signs as yield signs so they can roll through or stop when appropriate. Adopting a similar rule from Idaho, the Bicycle Transportation Alliance is trying to get the laws changed in Oregon to make biking easier while imposing no downside for automotive traffic.

This is an idea that should spread to all 50 states; it's the right-on-red movement of the 21st century.

Why conventional popcorn sucks, and what you can do about it

Dear Lou,

What about popcorn? Is it safe, healthy, and free of pesticides? What exactly is in the artificial butter flavor?

Thanks,

Survey says rich people want luxury!

According to an email we just received, eco-resorts have got to spiff up a bit if they want to attract "high spenders." Of 283 travelers surveyed, more than 60 percent would pay a premium for an eco-resort. But among the delicious tidbits: "Air conditioning and Internet access were the two most missed items if not available."

This comes courtesy of a company that's building "chic eco-homes" at the tip of a biosphere reserve in the Philippines. Sigh.

Maintaining healthy wild-oyster beds isn't quite as easy as oyster pie

Pearl, interrupted. I have long been partial to oysters. But it wasn’t until a few years ago that I came to understand the environmental challenges they face. Many folks assume that water pollution poses the main threat to oysters. Turns out the real damage comes from water scarcity — specifically, a lack of freshwater draining […]

New York Times creates dedicated environmental reporting team

This is extremely kick-ass news: The New York Times is creating a dedicated unit of eight reporters, with their own full-time editor, to cover environmental stories.

Columbia Journalism Review has all the details:

That editor is Erica Goode, a former behavior and psychology reporter turned Health editor who has been at the Times since 1998 and spent her last year in Baghdad covering the Iraq War. Her impressive team comprises Andrew Revkin and Cornelia Dean from Science, Felicity Barringer and Leslie Kaufman from National, Elisabeth Rosenthal from Foreign, Mia Navarro from Metro, and the Washington bureau's Matthew Wald, who writes for the paper's Energy Challenge series (another multi-department project).

The energy impact of web searches is very low

Some myths are hard to kill. The Times Online "reports":

Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research ...

While millions of people tap into Google without considering the environment, a typical search generates about 7g of CO2 Boiling a kettle generates about 15g. "Google operates huge data centres around the world that consume a great deal of power," said Alex Wissner-Gross, a Harvard University physicist whose research on the environmental impact of computing is due out soon.

The overhyping of the internet's energy use goes back a decade, pushed by two right-wing deniers, Mark Mills and Peter Huber. They were actually using their easily-refuted analysis to argue against climate restrictions -- I kid you not. In this 1999 press release [PDF] from the laughably-named denier group, the "Greening Earth Society," Mills says:

While many environmentalists want to substantially reduce coal use in making electricity, there is no chance of meeting future economically-driven and Internet-accelerated electric demand without retaining and expanding the coal component.

I ended up writing a major report debunking this myth and then testifying in front of the Senate Commerce committee [PDF] (i.e. John McCain) and the House [PDF] on the subject. Jon Koomey and others at Lawrence Berkeley National Laboratory (LBNL) did even more work debunking this nonsense (click here for everything you could possibly want to know on the subject).

There are actually two mistakes in the Harvard calculation. The first, which was the focus of my research, is the big picture issue. What is the net energy consumed by the internet? I argue the internet is a net energy saver -- and a big one -- since it increases efficiency (especially in things like the supply chain) and dematerialization (it uses less energy to research online than in person). The fact that U.S. energy intensity (energy consumed per dollar of GDP) began dropping sharply in the mid-1990s is but one piece of evidence that internet- and IT-driven growth is less energy intensive.

I, for instance, am able to work at home and telecommute thanks to the Internet and a broadband connection. That saves the energy consumed in commuting and a considerable amount of net building energy: Most people's homes are an underutilized asset, which consume a great deal of energy whether or not they are there.

The other mistake just involves the more narrow question of how much energy is consumed by Googling. Wissner-Gross says it is 7g of CO2 per search. My LBNL colleagues say that is way too high, and Google itself has rebutted that analysis with their own, which I reprint here:

A photo tour of the green concepts and cars from North American Int'l Auto Show

The North American International Auto Show opened in Detroit with a bang. Literally. Apparently, the Chrysler Pentastar fell from the ceiling and startled a cluster of journalists as well as billionaire investor Wilbur Ross and his entourage. No one was hurt, but the portentous crash may be more than symbolic for the American auto industry if their bets on electric and hybrid vehicles fail to deliver, or if China's BYD motors beats them to the punch with their plug-in F3DM.

Though subdued -- Chrysler left the steer back at the ranch this year -- the more "rational" Detroit Auto Show saw more hybrid and electric vehicles debuts than first-generation Prius-owners could have possibly imagined 10 years-ago. The Chrysler Circuit, Lexus HS 250h, third-generation Toyota Prius, new Honda Insight, Fisker Karma S, Lincoln Concept C, BMW Concept-7, and the smart ed -- which will be powered by Tesla batteries -- comprise just a smattering of the electric and hybrid concepts and production models that will start to roll off respective assembly lines by the end of this year.

Join the local movement with Grist

If you call Seattle home, we've got news for you ...

First things first: Howdy, neighbor! Grist is based in Seattle, too. Sure, we've got our political reporter in D.C. and an organic farmer in N.C., but most of us live and work -- and try to be as green as we can be -- within spitting distance of the Space Needle (relatively speaking, that is).

That's why we've launched Grist Local: Seattle, a weekly email featuring event listings, sustainable business profiles, and other news about the green scene in the Emerald City. You can get it zapped straight to your inbox every Wednesday for the low, low price of free! (And worth every penny.)

In fact, if you sign up now, you'll get your very first Grist Local email bright and early tomorrow (fresh off the presses). Here's a sneak peak:
