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?

Ethanol is an octane booster. Gas needs this to burn properly in modern car engines. Other alternatives are lead and MTBE. Both being pretty bad for us.
Yes you can still buy gas with all those and there is an argument for their use but for daily drivers, Ethanol is by far the safest.
