Which energy source is commonly made from corn in the United States?

• A. Petroleum
• B. Ethanol
• C. Natural gas
• D. Solar energy

Answer: (B)

Ethanol is commonly made from corn in the United States due to the country’s substantial corn production and the agricultural infrastructure that supports the conversion of corn into fuel. Ethanol is a type of biofuel that is created through the fermentation of sugars found in corn, making it a renewable energy source. This process involves breaking down the starches in corn into sugars and then fermenting those sugars with yeast to produce ethanol and carbon dioxide. The production of ethanol from corn is promoted for various reasons, including reducing dependence on fossil fuels, lowering greenhouse gas emissions, and supporting agricultural economies. The U.S. government has implemented policies and subsidies to encourage the use of ethanol as an alternative to gasoline, leading to its widespread availability at gas stations across the country. This choice aligns with the national strategy of promoting renewable energy sources, and it is characteristic of efforts made to utilize existing agricultural resources for energy production, which is distinctly different from the other options provided.
