Statement I: Incorrect. Between Brazil and the United States, the US actually produces more ethanol than Brazil. The US is the world's largest ethanol producer, primarily from corn, while Brazil is the second-largest producer.
Statement II: Correct. This accurately describes the different feedstocks used - the United States primarily uses corn for ethanol production, while Brazil predominantly uses sugarcane. This difference in feedstock reflects the agricultural strengths and climatic conditions of each country.
The feedstock difference is significant as sugarcane-based ethanol generally has better energy efficiency and lower carbon emissions compared to corn-based ethanol.
