Yes, cars can indeed run on ethanol. Ethanol is a renewable biofuel made from plant materials, typically derived from crops like corn, sugarcane, or switchgrass. It is a type of alcohol and is commonly used as an alternative fuel to gasoline in certain regions around the world. Ethanol can be blended with gasoline to create various ethanol-gasoline mixtures, with the most common being E10 (10% ethanol and 90% gasoline) and E85 (85% ethanol and 15% gasoline). These blends can be used in conventional gasoline cars' engines with little to no modifications.
Running cars on ethanol has several benefits:
Renewable: Ethanol is derived from plant sources, making it renewable and reducing our dependence on fossil fuels.
Lower emissions: Ethanol has a lower carbon content than gasoline, leading to reduced greenhouse gas emissions when used as a fuel.
Supports agriculture: Ethanol production often utilizes crops, supporting agricultural economies.
Domestic production: Many countries have the resources to produce ethanol domestically, reducing reliance on imported oil.
However, there are some considerations when using ethanol as a fuel:
Energy content: Ethanol has a lower energy content than gasoline, meaning vehicles may have slightly lower fuel efficiency when using ethanol blends.
Corrosion: Ethanol's corrosive properties may require some adjustments in fuel system components in older vehicles not designed to handle ethanol blends.
Availability: The availability of ethanol as a fuel can vary depending on the region and the support it receives from the local government.
Land use concerns: The production of ethanol from certain crops can raise concerns about competition with food crops and potential impacts on land use.

To run on higher ethanol blends like E85, a vehicle needs to be specially designed or modified to handle the higher ethanol content. Flex-fuel vehicles (FFVs) are capable of running on various ethanol-gasoline blends, including E85.
In summary, ethanol is a viable and environmentally friendly alternative to gasoline, but its widespread adoption faces some challenges and depends on factors such as government policies, infrastructure, and vehicle technology.
