High Food Prices Hurt Consumers and Biofuels Companies

Yesterday, the New York Times wrote: “A United Nations food agency called on Tuesday for a review of biofuel subsidies and policies, noting that they had contributed significantly to rising food prices and the hunger in poor countries. With policies and subsidies to encourage biofuel production in place in much of the developed world, farmers often find it more profitable to plants crops for fuel than for food, a shift that has helped lead to Read More >

This Week in Science

A group of preeminent academics put forward a policy proposal on regulating the development of cellulosic biofuels in the pages of Science magazine last week. They point out the urgent need to think about the unintended consequences of alternative fuels in order to achieve outcomes that are substantially better than “business as usual.” They conclude: Legislated environmental performance standards for cellulosic ethanol production could, for example, go far towards promoting sustainable outcomes. Such standards could Read More >

Life Cycle Analysis, International Land Use Change and Uncertainty

Bruce Dale, University Distinguished Professor of Chemical Engineering at Michigan State University, shared this presentation that he gave during a webinar hosted by the North Central Bioeconomy Consortium. In it, he highlights the number of factors in Life Cycle Analysis and Indirect Land Use Change (ILUC) models that produce uncertainty – in other words, if the assumptions or data for these factors change, how much do the results change. Dale is primarily examining the “carbon Read More >

Does Oil Cause Indirect Land Use Change?

I’ve been paying a lot of attention recently to new analyses attempting to model carbon emissions from indirect land use change, which is the conversion of land needed to maintain an international balance of supply and demand for agricultural crops, an effect that is heavily determined by crop prices. These new analyses raise a question about the existing assumption that oil has zero effect on land use change. Tim Searchinger, the lead author of one Read More >

2008 is a Good Year for Algae

And we’re not just talking about sushi here.  According to Greentech Media 2008 has been a banner year for venture capital financing of algae based biofuel companies. $179.5 million to date, according to numbers from the Cleantech Group. That compares with what appears to be about $32 million raised last year, based on a Cleantech Group chart of quarterly totals that doesn’t list the actual numbers And, elsewhere in the blogosphere algae biofuels are getting Read More >
