Baslim, you forgot your carbon cycles! Plants absorb CO2 and convert it into glucose via photosynthesis using sunlight. The glucose in plants is converted into ethanol using using thermochemical means. You failed to mention how much more energy is used to create fossil fuels than make bioethanol. 2times more energy is used to drill for oil, refine it into gasoline than is used to make bioethanol.
