Ignore those flashing lights! Full speed ahead!!

Yawn. Another story about the way production of biofuels (inferior substitutes for a commodity that is wasted in gargantuan quantities daily) consumes many times their weight in water, a truly vital liquid.

The money quote, the perfect encapsulation of all that is stupid, is here:

State Sen. David Johnson, the top-ranking Republican on the Senate Agriculture Committee, said he will not support regulations on how ethanol facilities use water until he sees proof that Iowa's aquifers are in trouble.

You go, Senator! Never address a problem until it's a crisis, that's the spirit! You are a true credit to your species, sir.

Why bicycling is 25 percent better than you thought

Your car's greenhouse-gas emissions are about 25 percent worse than you think.

How so? Well, for each gallon of gas you burn in your engine, there's the climate equivalent of another quarter-gallon or so embedded in your consumption. What that means is this: the gasoline you use didn't just magically appear in your tank -- it was extracted, refined, and transported to your local station. And all that activity released emissions.

It's a curiosity of our energy system (and other systems too, such as our food system), but it's a curiosity that bears closely on our thinking about how to reduce greenhouse-gas emissions. Stay with me for a moment.

It's usually assumed that each gallon of gas releases about 19.5 pounds of CO2 into the sky. (Some quibble, and argue that it's 19.4 or 19.6. But whatever.) Basic physics dictates that a gallon of gasoline combusted will release a more-or-less fixed amount of CO2. But from a public policy perspective, physics isn't the whole story.

A car company takes a step in the right direction — and it’s GM!

It's a pretty short step from here to letting OnStar drivers pay for auto insurance by the mile; that's a plus everywhere, but especially in states like Michigan, where it would help turn what had been very high fixed costs into proconservation variable ones.

Now if only the state would stop charging all drivers the same flat fee (about $125/yr) for the catastrophic claims fund -- put it into the price of gas or something.

GM's inspiration was to realize that OnStar's global positioning satellite technology gave GMAC a reliable, low-cost way to measure the actual mileage of GMAC policyholders, allowing those who drive less to share in GMAC's reduced underwriting costs. If this cooperative undertaking leads more people to subscribe to OnStar and purchase GMAC auto policies, well, that's just a chance GM will have to take.

Are we raping the planet in some cracked attempt to look hot?

Got it? You'll flirt and flaunt it. But the human drive to mate could be killing our planet and ultimately our species, according to Matt Prescott via the BBC. We're collectively thinking from the seat of our pants and using the wrong brain, so all of our little earth-saving intentions add up to vain fluffing, he adds. Why? Cheap energy and oil have given us new, ecologically toxic ways to compete for partners:

Highlights from a report on the state of the U.S. carbon market

Yesterday morning I attended a "special presentation" of the carbon market survey David summarized earlier. The panel discussion was a chance for the report's authors to present the findings to industry participants. A couple of further comments, for those interested in this topic:

DIY solar

DIY Solar. Love it. Just don't let your homeowner's association see it.

In other news, at the American Solar Energy Society conference in Cleveland last week, First Solar -- the same First Solar that recently announced the sale of $1.28 billion worth of modules -- gave a presentation in which they announced that based on current cost curves, they will be selling around $1.25/W in the 2010-2012 time frame.

That, friends, is cheap solar. If the industry can continue to bring down installation costs commensurately -- and that is done by developing local solar programs, creating local solar markets, and investing in local solar installers -- then solar will be at grid parity in a lot of locales.

China’s emissions aren’t really China’s

If you want a Chinese perspective on global warming, a good place to start is this China Daily opinion piece, "Climate change is reshaping global politics." Pang Zhongying, a research fellow with the Joint Program on Globalization under the CRF-Carnegie Endowment for International Peace, makes some points worth remembering, especially:

Western countries and industrialized Asian nations like Japan and the Republic of Korea have moved many of their factories to developing countries such as China and India, where cheap labor allows them to manufacture at lower costs than at home. This globalization of production has resulted in the discharge of much more waste in poor nations that otherwise would have been released in developed countries. As a matter of fact, not all of the greenhouse gases released "in China" or "from China" are really "China's".

Think of our large and growing trade deficit with China as the U.S. exporting industrial greenhouse-gas emissions. Worse still, China has a more coal-intensive industrial base, so producing things there generates far more pollution than if we had produced the same goods here.

Clothing companies start to come clean on chemicals

A few weeks ago, a good friend of mine invited me to an apparel industry environmental seminar chock full of good industry types. Seminars of this nature are always dreadfully boring, but it's worth it because you get the inside scoop on what the industry is (and unfortunately isn't) talking about. The principle topic was regulated substances and chemicals, how to move toward green chemistry alternatives, and how to manage all the issues associated with regulations. The meeting was the first important step in getting companies like Ann Taylor, Liz Claiborne, L.L. Bean, and others to begin taking the steps needed to beef up their consumer-protection standards.

The buzzword of the day was RSL, or "Restricted Substance List." Most RSL's are either proprietary information or outdated. That is all changing thanks to the American Apparel & Footwear Association's Environmental Task Force, which spearheaded the seminar.

On June 27, AAFA released an RSL to help textile, apparel, and footwear companies take the first step in regulating -- and, in some cases, eliminating -- certain contaminants from their products. I emphasize "first step" because many of the companies sitting in the auditorium were only marginally aware that so many chemicals and substances made up the DNA of their outfits.

Environmental peacekeeping runs into authoritarianism

My friend and colleague is in jail. Unjustly.

Her name is Haleh Esfandiari, and she is a grandmother. In early May, she was thrust into solitary confinement in Iran's Evin Prison with a single blanket. She hasn't been allowed to meet with her friends, family, or lawyers since then. This picture shows Evin Prison nestled within the leafy northern suburbs of Tehran at the foot of snowcapped mountains, but the prison has none of the bucolic qualities that the image suggests. "Notorious" is the ubiquitous descriptor.

Haleh's "crime" is doing what we do every day here at the Woodrow Wilson International Center for Scholars in Washington, D.C.: provide a safe space where scholars, policy-makers, and ordinary men and women can learn from one another through open, nonpartisan dialogue on today's most pressing issues. Or at least we thought it was safe.

Solar confusion

This is a neat concept — a solar water filter — brought to us by reader Zack Scott: But I’m confused. Does this work, say, if I’m lost in the woods and waterless? Does it filter out enough of the undesired elements to render water safe for drinking? Thoughts from Gristmillers?
