  • Keeping the air conditioners running in muggy Pennsylvania

    Just back from visiting the family in Pennsylvania, where temperatures were hitting the high 90s. It was the kind of sticky, muggy, oppressively hot weather that reminds me why I live in the cool corner that is the Pacific Northwest.

    As air conditioners were blasting away everywhere and lights were flickering, I was thinking that grid operators must be calling on every demand-response resource they could.

    Back into post-vacation action, I came across an Aug. 10 release [PDF] from PJM Interconnect that confirmed it. The power grid was on emergency status and PJM, in fact, drew a record demand response -- 1,945 megawatts -- equal to a fair-sized city.

    PJM also reduced voltage in the overall system by 1,000 MW, explaining those flickers. So I actually lived through the scenario with which I opened "Adventures in the smart grid no. 2." Damned glad they kept those air conditioners on.

  • Hmmm …

    James Connaughton says George W. Bush wants to be an "honest broker" on global warming. Sound familiar?

  • NYC debates grass v. artificial turf on playing fields

    This NYT piece is interesting in that oh-I-never-thought-of-that sort of way. Grass playing fields are — in New York City, at least — an endangered species: To avoid the ignominy of being trampled underfoot, the grass fields need to be idle all winter, and once a week the rest of the year. As a result, […]

  • And at what temperature Greenland’s ice sheet will melt

    Climate tipping points have been the subject of much debate and confusion. Now Professor Tim Lenton of the University of East Anglia has published a very good piece, "Tipping points in the Earth System," giving some intellectual substance to the notion.

    Not surprisingly, the tipping point Prof. Lenton worries about most is the disintegration of Greenland's ice sheet. He told The Guardian:

    We know that ice sheets in the last ice age collapsed faster than any current models can capture, so our models are known to be too sluggish.

  • Friday music blogging: Jens Lekman

    Today we bring you a Swedish singer-songwriter named Jens Lekman. On the surface, Lekman’s music is a bit of a throwback: mannered, melodic, occasionally orchestral pop, delivered with a precise baritone. It wouldn’t be out of place alongside Frank Sinatra. But listen a little closer and you hear a deadpan wit, a post-ironic self-effacement that […]

  • Is it really a savior for smallholder farmers in the global south?

    In the latest Victual Reality, I addressed the "eat-local backlash" — the steady trickle of media reports seeking to debunk the supposed social and environmental benefits of eating from one’s foodshed. Some of the charges are easy to refute. Hey, in Maine, it takes more energy to produce hothouse tomatoes in January than it does […]

  • Substitution isn’t the solution to peak oil

    The growing recognition that the world is at or nearly at the all-time peak of conventional oil production (meaning from that point on, oil flows will inexorably decline at some unknown rate) has prompted a furious search for replacements, all intended to keep the high-carbon, high-flying, automobile lifestyle going.

    Like crack addicts warned of a future shortage, we are literally searching the corners of the Earth to figure out how we're going to get our fix when times is tight.

    But given our climate crisis, peak oil could be appreciated as a push in the direction we already have to go (a decarbonized society). If we adopt the oil depletion protocol suggested by Colin Campbell, and made more widely known by Richard Heinberg, we can improve our resiliency, our health, and our social well-being -- and avoid the chaos that comes when a junkie loses his supplier while still stuck in full-blown addiction.

    New Scientist offers yet another argument for this approach:

  • A virtual world

    I scream, you scream, we all scream for an orangutan selling ice cream. On WWF’s virtual island in online world Second Life. From the press release: On Conservation Island, if residents "buy" an ice-cream from Mr Tangee, the orangutan who runs the ice-cream van, they will have the chance to learn that plantations to provide […]

  • A new technology to reduce GHG emissions from coal plants

    coalfiredpowerplant.jpg The carbon capture and storage (CCS) discussion has focused on pre-combustion capture of CO2, since it has long been assumed that it is easier and cheaper than trying to capture the CO2 post-combustion from the flue gas (exhaust stream). The problem is: (1) that approach limits CCS to new coal plants, and (2) that requires utilities to build integrated gasification combined cycle (IGCC) plants, which are more expensive to build and more expensive to maintain.

    Post-combustion capture would allow CCS to be retrofitted on existing coal plants. If it proves practical and affordable, that would be a major breakthrough in efforts to control greenhouse-gas emissions. Last week brought us this announcement:

    BP Alternative Energy and Powerspan Corp. today announced their collaborative agreement to develop and commercialize a post-combustion CO2 capture process for conventional power plants.

    More details on this potentially important technology below:

  • Eco-events all over the world

    There's a rash of "greener" fashion weeks popping up everywhere for the spring 2008 fashion season. And there must be an alignment of the stars or the higher workings of an omnipotent green god, because there is barely any overlap in dates. If you were so inclined, it would be possible for you to attend every single one of the shows listed below -- though the jet lag and carbon emissions from such an excursion might leave you feeling a bit ... restless.

    I'll be in Seattle, Paris, and New York, and maybe San Francisco, so please drop in and say hello if you are nearby.

    As enthusiasm for the green design movement continues to grow and the market becomes more robust and sophisticated, it is my (secret) hope to dethrone the Karl Lagerfelds of the world, who went on record to say, "If you want social justice, be a social worker."

    Down, down with the status quo. Hear, hear for revolution.
