Climate Climate & Energy

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.

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.

Just When You Thought It Was Safe-ish

Rush-hour steam-pipe explosion rattles Manhattan An 83-year-old underground steam pipe exploded near New York City’s Grand Central Terminal during rush hour yesterday, causing one death, more than 40 injuries, and a lot of rattled nerves. After the initial explosion — a plume as high as the Chrysler Building that onlookers compared to a volcano, the […]

This week’s coal-sucks update

I just realized it’s been almost a week since I’ve published a coal-bashing post! This cannot stand. I’ll have to dig back a bit … ah, here we go: a new study from the Carnegie Mellon Electricity Industry Center (CEIC) concludes that investing in plug-in hybrids would be much more sensible, in terms of both […]

BS green

Given the surge of interest in climate and energy, it’s no surprise that a lot of BS — rainforest-screwing biodiesel, everyone-screwing liquid coal, etc. — is getting passed off as "green" and bellying up to the public trough. Glenn Hurowitz calls out some of the more egregious offenders.

A new report with numbers and stuff

Our discussion of carbon offsets has been rather hand-wavey — lots of intuitions and moral judgments and gut feelings flying around. This obviously offended the gods of wonkitude, who have now seen fit to deliver unto us a report on the voluntary carbon credit market, containing some sweet, sweet numbers and graphs. The report was […]

Here’s wishing you plentiful petroleum

I give you Trilby Lundberg, publisher of the Lundberg Survey of gas prices: I’m hoping that consumers will see through the rhetoric about consuming less, demanding less, as faulty. It is not a given that consuming less will be good for our economy or for our personal freedom. It is not even established for our […]

Deader Than Ever

Biofuels could contribute to historically big Gulf of Mexico dead zone Still think corn-based biofuels will save the world? Here’s another piece of the no-they-won’t puzzle: Researchers say more intensive farming of more land in the Midwestern U.S. — in part a result of the push for more corn production — could contribute to the […]
