Biofuels Feedstocks – Yield Matters
The following post was submitted by Richard Hamilton, president and CEO of Ceres, Inc. Technology is playing a critical role in maximizing the inherent advantages of dedicated energy crops. Through advanced plant breeding, public and private researchers are increasing yields both in terms of tons per acre (field yields) and in terms of gallons per ton (through traits that improve conversion). Higher yields not only have a significant impact on reducing production costs of cellulosic Read More >
No land cleared for biofuels
One of the many flaws of the Science Magazine studies on biofuels and land use changes is their assumption that an acre of crops dedicated to biofuels in America will lead to an acre of deforestation elsewhere in the world. In fact, in a recent interview with the Nature Conservancy (his employer) Joe Fargione, the author of one of the studies, goes well beyond the data supported by his study and claims that “Increased demand Read More >
The Truth is Out There: But you have to look
Biofuels are great! There. I’ve been wanting to say that. And I say that not just because I work here at BIO, but because the science in the Science papers needs a little examining. There is misinformation all over the blogosphere. For example, Siko, in the German Carzone posting the following comments today, “Two studies shows that replacing fossil fuels with corn-based ethanol would double greenhouse gas emissions over the next three decades. The studies Read More >
An Interesting Coincidence?
The papers published in Science two weeks ago continue to make headlines, as a quick search of Google News will show. Also this week, oil reached the $100 per barrel mark. Meanwhile, debate over the Science papers continues, and some truths are out there, as we said when we began this public forum. Nathanael Greene of the Natural Resources Defense Council notes the media have made rather simplistic assessments of the Science papers.Greene writes that the Read More >
Scientists Respond to Carbon Debt Issue
Reaction to the ScienceXpress articles by Searchinger et al. and Tilman et al. has focused on the assumptions the teams of authors used in measuring greenhouse gas emissions from changes in land use. As Michigan State University Professor of Chemical Engineering Bruce Dale points out, Both of these papers are modeling studies and are therefore completely dependent on the validity of the models themselves and also of the basic assumptions and data input to the Read More >
