Fuel from wood chips, grass, and algae? According to President Obama, that is part of the solution to the problem of America's dependence on foreign oil. Along with greater use of domestic natural gas, the President outlined his plan for increasing the use of biofuels such as ethanol and naturally-derived oils. He wants to stimulate research and production of new and more efficient biofuels and expand the use of alternatively powered vehicles in order to wean the country from its reliance on oil.
