Regarding the Algae biofuel story, the study does not appear to be very well done as it assumes algae would need to be fertilized from a non-renewable resource. However, most research with algae biofuels is in the area of using waste water and other manufacturing effluent such as carbon dioxide as the nutrient sources. In fact, the Algal Biomass Organization released a statement disputing the study. See GCC: Algal Biomass Organization Questions Findings of Recent Algae Life Cycle Study
