All plans are for increased biofuels, but now with a little more realism attached. More emphasis is placed on cellulosic ethanol research and direct use fuels like butanol that can be used in standard gasoline engines. This is not so much a shift in direction, as re-defining it. The change is the increased thought in the economics of the biofuels, and the ideas to stabilize investments in them. When gas prices can shift 600% in 2 years, investments in new fuel technologies are risky investments, no matter how sound the technology. The idea is to cushion the market from the swings in gasoline prices while still maintaining an overall profitability in biofuels.
