  • Lovins and Sheikh defend definition and record of micropower

    This is a guest essay from Amory B. Lovins and Imran Sheikh of the Rocky Mountain Institute. It is part two of a series; see part one here.

    -----

    Part two of David Bradish's critical look at "The Nuclear Illusion" (PDF) raises two additional issues to which we respond here. As in his first critique, it appears that, unable to rebut and hence unwilling to address our paper's data and logic, Mr. Bradish must content himself with trying to manufacture an illusion of confusion.

    Does RMI's data fit their definition [of micropower]?

    Yes, precisely; it just doesn't fit various other definitions that Mr. Bradish has invented on his own. We clearly defines micropower (an Economist magazine term) thus at pp. 11-12:

    1. onsite generation of electricity (at the customer, not at a remote utility plant) -- usually cogeneration of electricity plus recovered waste heat (outside the U.S. this is usually called CHP -- combined-heat-and-power): this is about half gas-fired, and saves at least half the carbon and much of the cost of the separate power plants and boilers it displaces; [and] 2. distributed renewables -- all renewable power sources except big hydro plants, which are defined here as dams larger than 10 megawatts (MW).

    Mr. Bradish arbitrarily and wrongly assumes "that the size of 'micropower' plants is 10 MW or less," then claims this is our definition and contradicts our data. It's not and it doesn't. Our 10 MW limit applies only to small hydro, distinguishing it from big hydro using the most conservative criterion. Any power source except small hydro can be larger than 10 MW but still meet our micropower definition: WADE's onsite-fueled-generator definition, which we've adopted, includes onsite units up to somewhat over 180 MWe for gas turbines (though few actual units are over 120 MWe) and up to 60 MWe for engines, as well as onsite (nearly always cogenerating) steam turbines of any size if they're in China and India; however, WADE's database excludes steam turbines elsewhere, and all units below 1 MWe.

  • Gallons per mile: A better way to express fuel efficiency

    Let's say a pollster walks up to you and asks you the following question:

    "A town maintains a fleet of vehicles for town employee use. It has two types of vehicles. Type A gets 15 miles per gallon. Type B gets 34 miles per gallon. The town has 100 Type A vehicles and 100 Type B vehicles. Each car in the fleet is driven 10,000 miles per year." The town wants to replace these vehicles with corresponding hybrid models in order to to reduce gas consumption of the fleet and thereby reduce harmful environmental consequences.

    Should they (1) replace the 100 vehicles that get 15 mpg with vehicles that get 19 mpg , or (2) replace the 100 vehicles that get 34 mpg with vehicles that get 44 mpg?

    If you are like the people who were actually surveyed by Richard Larrick and Jack Soll of Duke University, you chose option two. After all, an increase of 10 mpg clearly sounds better than a measly 4 mpg. And yet, some simple number crunching reveals that the town fuel efficiency is improved more in option one (by 14,035 gallons) than in option two (by 6,684 gallons).

  • Billy Crystal and David Letterman spoof ‘we’ campaign

    David Letterman and Billy Crystal spoof the "we" campaign:

  • Conservation good. Drilling stupid

    Op-ed in the Austin American-Statesman. Reads like a Grist post. Go figure.

  • Convicted eco-vandal sentenced to six years in prison

    Convicted eco-vandal Briana Waters has been sentenced to six years in federal prison and was ordered to pay $6 million in restitution for her role in the 2001 blaze that destroyed a University of Washington horticulture center. Waters was a student at The Evergreen State College in Olympia, Wash., at the time and allegedly acted […]

  • The toll of the shrimping industry on Southeast Asia

    Southeast Asia would have fared better during the tsunami and the recent cyclone if the majority of the region's coastal mangrove forests were intact. Everyone accepts that. But many of the mangroves have been cut for firewood, largely to make way for shrimp farming. The cost of the mangrove-loss to coastal fisheries is great, since much of the food chain spends its early years amongst the trees' roots.

    But the human cost, besides those lost in the flood waters, is also great: Labor abuses in the farmed shrimp industry are rampant. Read "The True Cost of Shrimp" (PDF) for details on the child labor, human trafficking, beatings, torture, and murder associated with these farms. There are also toxins that farm workers get to enjoy spraying into the shrimp pens to keep the critters from succumbing to infections. So, what to do?

  • Radioactive deja vu in the American West

    This is a guest essay from Chip Ward, author and board member of the Southern Utah Wilderness Alliance. It was originally published on TomDispatch and is republished here with Tom’s kind permission. —– In the American West, we take global warming personally. Like those polar bears desperately hunting for dwindling ice flows, we feel we’re […]

  • Select Committee examines the benefits of smarter urban planning

    The House Select Committee for Energy Independence and Global Warming held a hearing on Thursday about the opportunities for better urban planning to reduce energy use and greenhouse-gas emissions. “Planning Communities for a Changing Climate” brought together a panel of experts on “smart growth,” clean air policy, and transit. Witnesses included Dr. Sultan Al Jaber, […]

  • New York state passes bill to create detailed map of cancer cases

    In an effort to educate the public about correlations between cancer rates and environmental factors, the New York state legislature just passed a bill that would create a detailed map of cancer cases in the state. The online map would plot the neighborhoods of cancer patients as well as the location of industrial facilities like […]

  • Worse heat waves, floods, droughts, hurricanes, and storms to come

    Originally posted at the Wonk Room.

    The traditional media rarely discusses extreme weather events in the context of global warming. However, as the Wonk Room Global Boiling series has documented, scientists have been warning us for years that climate change will increase catastrophic weather events like the California wildfires, the East Coast heatwave, and the Midwest floods that have been taking lives and causing billions in damage in recent days.

    Yesterday, the federal government released a report that assembles this knowledge in stark and unequivocal terms. "Weather and Climate Extremes in a Changing Climate," by the multi-agency U.S. Climate Change Science Program with the National Oceanic and Atmospheric Administration in the lead, warns that changes in extreme weather are "among the most serious challenges to society" (PDF) in dealing with global warming. After reporting that heat waves, severe rainfall, and intense hurricanes have been on the rise -- all linked to man-made global warming -- the authors deliver this warning about the future:
