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?

They produce the same amount of CO2 per energy burned but there is just less energy in ethanol per galon. The idea is that ethanol comes from plants which absorbed that CO2 while growing the year before. So year over year the amount of CO2 in the atmosphere doesn’t increase. It doesn’t work though, we could never replace fossil fuels by using bio mass. But it is cheaper and easier to produce corn that isn’t fit for consumption and you can use GMOs for that more easily. So it is lucrative. It’s basically a green washing scam to funnel subsidies to farmers.
