What are the main benefits of cellulosic ethanol and other second-generation biofuels?
There are three primary benefits of second-generation biofuels. First, second-generation biofuels further reduce greenhouse gas (GHGs) emissions. According to the US Department of Energy’s GREET model, cellulosic ethanol has the potential to reduce GHGs by up to 87 % compared to gasoline. Second, by diversifying our energy sources, second-generation biofuels reduce our dependence on petroleum as our main source of energy. Finally, second-generation biofuels, when produced from waste, reduce and ultimately eliminate the use of landfills by converting waste materials into fuel for our cars.
