Question map
Consider the following statements : Statement I : Of the two major ethanol producers in the world, i.e., Brazil and the United States of America, the former produces more ethanol than the latter. Statement II : Unlike in the United States of America where corn is the principal feedstock for ethanol production, sugarcane is the principal feedstock for ethanol production in Brazil. Which one of the following is correct in respect of the above statements?
Explanation
**Statement I is incorrect.** The United States is the world's largest producer of ethanol, having produced over 15 billion gallons in 2021[1] and 2022. In comparison, Brazil's corn ethanol is expected to reach 10 billion liters (2.64 billion gallons) by 2025/26, and sugarcane ethanol has remained relatively stable at around 28 billion liters (7.4 billion gallons) annually[2], giving Brazil a total of roughly 10 billion gallons. Therefore, the United States produces more ethanol than Brazil, not the other way around.
**Statement II is correct.** Sugarcane ethanol has remained relatively stable at around 28 billion liters annually in Brazil, while corn ethanol is expected to account for nearly one-third of Brazil's total ethanol production[2], confirming sugarcane remains the principal feedstock in Brazil. Additionally, sugarcane juice can be used to prepare molasses which is fermented to give alcohol (ethanol), and some countries now use alcohol as an additive in petrol[3]. The United States primarily uses corn for ethanol production, as it is the dominant corn-based ethanol producer globally.

PROVENANCE & STUDY PATTERN
Guest previewThis is a classic 'Comparative Economic Geography' question. It fuses static agricultural knowledge (Crop distribution: Corn vs Sugarcane) with industrial output rankings (Energy production). While books confirm the feedstock, the production ranking requires current economic awareness or logical derivation from the scale of US agriculture.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: As of 2025, which of the two major ethanol-producing countries—Brazil or the United States—had the higher annual ethanol production by volume?
- Statement 2: As of 2025, is corn the principal feedstock for ethanol production in the United States?
- Statement 3: As of 2025, is sugarcane the principal feedstock for ethanol production in Brazil?
- Provides Brazil's recent/2025-era ethanol volumes broken down by feedstock and gives gallon equivalents.
- Shows Brazil's sugarcane ethanol ~28 billion liters (7.4 billion gallons) plus corn ethanol ~10 billion liters (2.64 billion gallons), implying Brazil's total ≈ 10.04 billion gallons by 2025/26.
- States the United States is the world's largest ethanol producer and gives a recent annual production figure.
- Reports the U.S. produced over 15 billion gallons in 2021 and 2022, a level higher than Brazil's ~10.04 billion gallons indicated for 2025/26.
States the United States has the highest maize harvest in the world (major feedstock for ethanol).
A student could combine this with the outside fact that much U.S. ethanol is corn-based to infer the U.S. has large ethanol-making capacity from maize production.
Defines crops used to produce liquid biofuels (ethanol), listing sugarcane and maize among primary feedstocks.
Use this rule to link crop-dominance (maize for U.S., sugarcane for Brazil) to each country's likely ethanol production potential.
Notes raw sugar comes mainly from sugarcane and lists Brazil as a leading producer of sugarcane-derived sugar.
A student could combine Brazil's strong sugarcane production with the fact that Brazil commonly uses sugarcane for ethanol to infer high ethanol output potential.
Mentions sugarbeet and the U.S.A. as a producer, indicating the U.S. also has temperate-region sugar feedstocks usable for ethanol.
This suggests the U.S. has multiple ethanol feedstock sources (maize and beet), reinforcing its overall ethanol production capacity when combined with maize data.
