For those of us who actually invested in the corn ethanol industry in the 90s, and waited a dozen years to see any profit- we heard the same thing for the last 15 years, that cellulosic ethanol from switchgrass or corn stover, other biomass, is just 5 years down the road, once the appropriate enzymes are developed that can break down the starch. Yes, it is possible, but not yet ECONOMICAL. Corn ethanol is currently economic, and the "residue" is still good feed for bovines, bit limited for single-stomach animals like chickens, turkeys, hogs.- but usable at about 10% of their ration. Pimental "study" is often quoted to "prove" that it takes more energy to produce corn ethanol than what is gotten out of it. That study has been proven to be rubbish countless times- Pimental and his partner were employees of Shell Oil, and went out of their way to slant it. Even so far as to determine how much energy it took to mine the ore that was used to make the tractors and equipment to grow the corn. Just like when asked, paper or plastic at the store- I tell the clerk, Paper- we can grow trees, we cannot grow oil!.
