  • Tom Konrad on cellulosic electricity

    The following is a guest essay by Tom Konrad, a financial analyst specializing in renewable energy and energy efficiency companies, a freelance writer, and a contributor to AltEnergyStocks.com.

    Romm v. Khosla

    In a persuasive series of articles entitled "Pragmatists vs. Environmentalists" (Parts I, II, and III), Vinod Khosla has provided the reasoning behind his "dissing" of plug-in hybrids, which drew the ire of Joseph Romm. Neither seems to think the argument is settled, and Romm returned fire here.

    To summarize, Khosla argues that cellulosic ethanol shows more promise for reducing carbon emissions than plug-in hybrids, because the barriers to plug-ins (the need to improve batteries and clean up the grid) are harder to surmount than the barriers to cellulosic ethanol (the improvement of conversion technology). In his words,

    I consider replacing coal-based electricity plants (50-year typical life) a much longer, tougher slog than replacing oil with biofuels (15-year car life).

    Romm blasts back, reiterating the multiple problems of corn ethanol in response to the first of Khosla's series, but has not yet responded to his point about cellulosic. I thought I'd tackle the point myself.

    There isn't enough biomass

    According to the National Renewable Energy Laboratory's From Biomass to Biofuels (PDF) study, given all the available biomass in the United States, we will only be able to displace a little less than 2 billion barrels of oil equivalent a year. But we currently use about 7 billion barrels of oil a year, so to displace all our oil usage, we would need nearly a 4x increase in fuel efficiency (not the 1.5x increase in internal combustion engines Khosla talks about).

  • Wal-Mart CEO outlines lofty green goals

    Wal-Mart CEO Lee Scott made a big ol’ speech yesterday spelling out ambitious social, health, and environmental goals for the retail behemoth. Wal-Mart will work with other retailers to boost industry-wide green standards, said Scott, and, within five years, Wal-Mart suppliers will be required to meet stringent environmental standards — and may even be paid […]

  • Wal-Mart CEO lays out ambitious social and environmental goals for his company

    Yesterday, Wal-Mart CEO gave a fairly amazing speech, assessing the company’s progress on its social and environmental goals and laying out some extremely ambitious plans for the future. A taste: He then laid out sweeping plans for the company on several health and environmental issues, and he hinted that even more ambitious goals might be […]

  • Al Gore tells World Economic Forum the climate situation is dire

    In a speech spiced with signature phrases like “moral imagination” and “planetary emergency,” as well as plenty of references to future generations, Al Gore warned attendees at the World Economic Forum in Davos, Switzerland, that the climate situation is dire. “The climate crisis is significantly worse and unfolding more rapidly than those on the pessimistic […]

  • The latest eco-buzzword

    greenlanternrebirth6.jpgThe Washington Post has a good article yesterday on the explosion in the use of the term "green-collar" jobs. You will no doubt be hearing much more of this term since it is a favorite of Clinton and Edwards; Me and the Center for American Progress are on the bandwagon; and even the super trendspotting Tom Friedman has glommed onto it.

    No, it's not a perfect term. G-C jobs -- my effort to coin the ultimate eco-buzzword -- won't get you a green uniform and green power-ring like the Green Lantern Corps, although you will, coincidentally enough, be promoting green power. As the Post notes:

    ... while white-collar and blue-collar bring distinctive images to mind -- the mutual fund manager screaming into his BlackBerry, the coal miner coming home, coughing from a long day -- such iconic imagery is hard to find with the green-collar worker.

    Still, the term, popularized by social activists like Van Jones of the Ella Baker Center, does have a powerful ring to it [sorry about that], so I expect it will be around for a while. I will try to limit use to, say, once a month.

  • Kudos to Seventh Generation on a Hollywood moment

    I’m not saying I paid good money to see 27 Dresses this weekend. Nor am I saying that its ending, however formulaic, made me cry. What I am saying is how nice it was to see a generous, nearly full-screen shot of a Seventh Generation cleaning product clutched in Katherine Heigl’s frenzied hand. Not to […]

  • Seed-savers and greens unite to challenge Monsanto’s latest cash cow

    For years, candy makers and other industrial food manufacturers refused to use genetically modified sugar, fearing a consumer backlash. Photo: iStockphoto As a result, Monsanto’s Roundup Ready sugar beet — designed to withstand heavy application of Roundup, Monsanto’s herbicide — has been dead in the water. (Sugar beets, grown in the Midwest and Northwest, account […]

  • E.U. considers pollution charges on imports from U.S. and other climate scofflaws

    U.S. failure to enact limits on global warming emissions could cost American companies that export to the European Union.

    E.U. President Jose Manuel Barroso on Sunday said the European Commission is considering a charge on importers from nations without carbon limits. Companies from those countries may be required to buy carbon emissions allowances on exports into the E.U. This is intended to level the playing field with European companies who are already part of the European Emissions Trading System instituted to meet E.U. obligations under the Kyoto climate treaty.

    Barroso said the Commission could "require importers to obtain allowances (emissions permits) alongside European competitors ... There would be no point in pushing EU companies to cut emissions if the only result is that production and indeed pollution shifts to countries with no carbon disciplines at all."

  • Big names will discuss climate at World Economic Forum

    Business and political leaders are descending on Davos, Switzerland, for the annual World Economic Forum, which kicks off tomorrow. The forum will offer various climate-related sessions, including one led by Intergovernmental Panel on Climate Change Chair Rajendra Pachauri; one which will be a discussion between Al Gore and Bono; and one with the ominous title […]

  • Whole Foods to stop giving out plastic grocery bags by Earth Day

    Natural foods retailer Whole Foods has announced it will stop giving out plastic grocery bags by Earth Day due to the bags’ ubiquity and associated environmental problems. The company is opting instead for bagging customers’ groceries in 100 percent recycled paper bags and/or encouraging customers to bring their own reusable sacks. “More and more cities […]
