Ethanol vs. Gasoline: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
Ethanol is an alcohol-based fuel derived from plants, while gasoline is a petroleum-based fuel. Both are used in combustion engines but have distinct properties and sources.

Key Differences

Ethanol and gasoline are both common fuels, but they originate from vastly different sources. Ethanol is a type of alcohol derived primarily from fermented sugars in plants, especially corn in the United States. It's renewable, given its plant-based origin. Conversely, gasoline is a refined product of crude oil, which is a non-renewable fossil fuel.

When used as fuels, ethanol and gasoline have differing energy contents. Ethanol contains less energy per gallon compared to gasoline, which can affect the mileage a vehicle gets. While gasoline has been the traditional fuel for combustion engines, ethanol is often blended with gasoline to produce fuels like E10 or E85, denoting the percentage of ethanol present.

Environmental considerations also differentiate ethanol from gasoline. Burning ethanol tends to release fewer greenhouse gases compared to gasoline, making it a cleaner alternative in that respect. However, gasoline provides better efficiency due to its higher energy content, so vehicles can travel longer on a gallon of gasoline than on a gallon of ethanol.

From an economic standpoint, the production of ethanol, especially in countries with abundant agricultural resources, can help in reducing dependency on imported oil. Gasoline, given its origin from crude oil, is subject to global market fluctuations, geopolitical issues, and extraction costs. Ethanol's price, however, is influenced more by agricultural factors than global politics.

Safety and handling of ethanol and gasoline also have distinctions. While both are flammable, ethanol has a higher octane rating than gasoline. This means it can resist knocking in engines better than gasoline. On the other hand, gasoline is more volatile, making it easier to ignite under various conditions.
