You're forgetting the energy cost of converting the plant material into 
usable fuel, and the problem of plant waste, which will rot, which 
represents wasted energy. Biofuels aren't the simple solution they seem 
to be.

The sad fact is that most of the energy we produce is wasted, ie 
converted into heat without doing any useful work. I'm happy that my 
gasoline=powered car produces a lot of waste heat when I drive it in the 
wintertime, since the  heating system scavenges that heat and redirects 
it into the cabin. But otherwise, that waste heat is the cost of moving 
me from place to place. Most of the cost, in fact: at least 2/3rds of 
the fuel's energy is converted in waste heat. See my other post.
