  • The best U.S. transit systems you never knew existed

    When it comes to public transit in the U.S., there are certain predictable all-stars: the Metro in Washington, D.C., is convenient, efficient, and clean. The anthropomorphically nicknamed El and BART in Chicago and San Francisco are legendary. And everyone knows it’s easier to navigate New York City without a car than with one. But what […]

  • Hydrogen fuel cell cars are a dead end from a technological, practical, and climate perspective

    Using fuel cell vehicles and hydrogen from zero-carbon sources such as renewable power or nuclear energy has a cost of avoided carbon dioxide of more than $600 a metric ton, which is more than a factor of ten higher than most other strategies being considered today….

  • Ask Umbra on license plates

    Q. Dear Umbra, Today I obtained a Wisconsin driver’s license and plates, after nearly a year of denying my residency in America’s Dairyland due to my pride in my home state (which has produced gems such as Rod Blagojevich, and his hair). But instead of accepting my olive branch, the DMV issued me license plates […]

  • Critique of auto standards misses how they save consumers money compared to gas taxes

    Robert Stavins thinks an increased gasoline tax or cap-and-trade would make Obama’s tougher auto efficiency standards redundant.  This offers an excellent illustration of how even economists who are not market fundamentalists can miss the way well-designed regulation improves economic efficiency. Yes, cap-and-trade or a rising gasoline tax will reduce driving and gasoline use. But because […]

  • The folks behind the Nano take their vision to suburbia

    On paper, the biggest U.S. export is capital goods–aircrafts, semiconductors, medical equipment, and such. But we’ve been exporting something else in force to developing countries: the suburban lifestyle.
