    I live in a hundred year-old house where most everything is original: the windows (drafty), the walls (uninsulated), the furnace (burns oil).

After some well-publicized studies stated that corn-based biofuels might exacerbate CO2 damage to the environment, focus has shifted to these so-called "second generation" biofuels that use non-food crops such as switchgrass, wood chips or crop residues (e.g. all the parts of the corn plant that are currently wasted after harvest--the stalk, leaves and "cob").
