Eli5 Ethanol added to gasoline

1.38K views

Almost every station I go to has ethanol (up to 10%) added to gas. For a long time I had the option in my area to buy non ethanol gas but now it’s harder to find.

If a gallon of ethanol gets less mileage per volume than gasoline, then how is it better for the environment if I have to fill that much sooner on gas because the ethanol component lowers my tank range?

There is a long standing US policy that basically requires the government to do everything it can to ensure that we grow enough food for our population without imports.

However, nobody wants to eat only seasonal foods, and/or foreign produced foods might be cheaper, so imports are gonna happen anyway.

In order to create artificial demand that keeps food production high, other uses were derived for corn, the main growable staple in the US. Corn syrup and ethanol are two big ones, and a ton of it goes to feed meat.

If the US goes to war with the whole planet and we can’t get food imported, we just stop feeding the corn into industry and start putting it on plates.

I’m not saying it’s a good plan or a realistic worldview, but…. It is what it is.
