Algae #Biofuel Could Replace 17% of US Imported Oil
Photo: DoE/Pacific Northwest National Laboratory Seemingly perpetually just over the commercially-viable horizon, algae biofuels consistently show good potential both in terms of yield and not competing with food production to the extent that other feedstocks can. But they are nevertheless water intensive--not an insignificant concern considering projections of decreased water availability across parts of the US and in many parts of the world. So, without sucking up absolutely all the water from agriculture and all the other important things water is connected to (everything...), how much of current imported oil demand could be replaced with algae biofuels?
