The point of fuel made from biomass from algae rather than extracted from the ground is that the former is carbon neutral, while the latter is not. The algae consume atmospheric CO2 to grow, so that when burnt, an equal amount of CO2 is released back into the atmosphere, so no net increase in CO2 emissions. Burning fossil fuel releases sequestered CO2 into the atmosphere for a net increase in atmospheric CO2, which is a bad thing.
