Current State of Cellulosic Ethanol Production

Only a small part of most plants is sugar or starch, the part that can be digested by humans and fermented by yeast into ethanol. Most of the rest is cellulose. Naturally, using the bulk of the plant is more efficient. Better yet, we need not use our food plants. Some grasses store more energy in cellulose than does corn, and require far less nitrogen fertilizer, far fewer pesticides, and less process heat (energy).
The main drawback now is expense. Of course cellulose ethanol could be overdone like anything else, but much more could be produced with much less ecological damage. And with some plausible advances, it could be cheaper than gasoline. Read the current production cost
