Efficiency

Ethanol yields 25% more energy than the energy invested in its production, whereas biodiesel yields 93% more.

Biodiesel releases just 1.0%, 8.3%, and 13% of the agricultural nitrogen, phosphorus, and pesticide pollutants

Biodiesel also releases fewer air pollutants compared to ethanol

These advantages of biodiesel come from lower agricultural inputs and more efficient conversion of feedstocks to fuel.
