Ethanol is a biofuel that can be produced from the fermentation of certain plant materials, such as sugarcane, corn, and switchgrass. Maize and sunflower are examples of crops that can be used to produce ethanol. However, Jatropha and Pongamia are not commonly used as energy crops for ethanol production but are instead used to produce biodiesel. Jatropha is a hardy plant that can grow in marginal lands and produce oil-rich seeds that can be used to make biodiesel. Pongamia is another oilseed tree that is cultivated for biodiesel production.
