Tuesday Truth #36 – Ethanol Has Positive Energy Output

Categories: General Info

Ethanol has a positive energy balance – and that balance is constantly improving with new technologies. Here are some statistics:

  • Gasoline requires 1.23 BTUs to produce 1 BTU of energy, while ethanol requires only 0.74 BTU to produce 1 BTU of energy. Ethanol has a positive energy output while gasoline requires more energy than it actually produces.

  • Over the last 20 years, the amount of energy needed to produce ethanol from corn has significantly decreased because of improved farming techniques, more efficient use of fertilizers and pesticides, higher-yielding crops, and more energy-efficient conversion technology.
