Comment on 'Environmental life Cycle Comparison of Algae to Other Bioenergy Feedstocks'

摘要

The recent publication of "Environmental Life Cycle Comparison of Algae to Other Bioenergy Feedstocks" in Environmental Science & Technology by Clarens et al. (1), has generated significant attention within the bioenergy field. The authors of the study report that algae has greater greenhouse gas emissions, higher nutrient requirements, and greater water use relative to com, switchgrass, and canola bioenergy feedstocks. The analysis presented by Clarens et al.
