"Expanding algae as a cooking-oil ingredient seems promising despite the energy required to heat up fermentation tanks, says Stanford University sustainability professor Steven Davis, who studies agricultural emissions. Fermenting algae is likely to use less water than traditional agriculture while limiting CO2 emissions and the need for fertilizers, he says. Algae can also flourish in many different types of environments, Davis adds. 'If we can reduce the demand for conventional land-based oils, that could be a big win.'"
