New Biofuels Manifesto

University of Minnesota Professor David Tilman, Princeton University Visiting Scholar Tim Searchinger, Dartmouth Professor Lee Lynd and others involved in the debate over the environmental and social impacts of biofuels have published in Science magazine what amounts to a new manifesto on how biofuels can be done right. The authors list five biofuel feedstocks that are the best in terms of sustainability — “lower life-cycle greenhouse-gas emissions than traditional fossil fuels and with little or Read More >

Don't Rush to Judgment

In 1953 Linus Pauling and Robert Corey published their structure of DNA, 3 strands twisted around each other. Shortly after that James Watson and Francis Crick published the correct structure of DNA, the one on which the biotechnology industry is built.That is the way science goes. Scientists make discoveries, publish their work, and others come along to either support or dispute those discoveries. Imagine if we had just rushed to judgment back then and gone Read More >

Clouding Assumptions

Science magazine this week published an exchange between Vinod Khosla, the venture capitalist who has invested a great deal in alternative energy, and Timothy Searchinger and coauthor Richard Houghton critiquing and defending the February 2008 study, “Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change” The exchange reveals some of the nuances of indirect land use change arguments that have not been addressed. Khosla’s comments raise two important issues, allocation Read More >
