Can you use isopropyl alcohol versus ethanol for fuel?

Isopropyl alcohol (isopropanol) and ethanol can both be used as fuels, but they have different properties and efficiencies. Ethanol is more commonly used in fuel applications, such as in gasoline blends, due to its higher energy content and better combustion characteristics. Isopropyl alcohol, while it can be used as a fuel, typically has lower energy density and is less effective for large-scale fuel applications. Additionally, regulations and availability may favor ethanol over isopropyl alcohol for fuel use.
