Algae Biofuel Grown in Bioreactors Has 3.7x the Carbon Footprint of Petro-Diesel: Study
According to Anna Stephenson from the University of Cambridge, when algae is grown in clear-tubed bioreactors the energy required to move the algae around so that it gets enough sunlight means that per megajoule equivalent of fuel, the algae fuel has a carbon footprint of 320 grams while petro-diesel takes 86 grams.
