How energy-intensive are algal biofuels? asks new report

In Virginia, a new study from the University of Virginia casts doubt over the environmental credentials of algae as feedstock for biofuel. Though less transportation energy is used when algae is a feedstock versus when switchgrass or other farmed biomass is a feedstock, algae requires much more energy and water for processing than other biomass. The next step of research will look at value of different economic costs and benefits based on feedstock.
