We also have a 10% ethanol blend here in the greater Milwaukee area. However, I saw an article in the Wall Street Journal (a while back) that gave a mixed review of its green-ness. Specifically, it takes more energy to create the corn-based alcohol than you gain by burning it, so the processing plants (mostly located in Iowa) are pulling a lot of electricity (generated primarily by coal-fired plants in Iowa) to create the ethanol. Yes, the emissions coming out of my tailpipe are cleaner than if I was burning unadulterated gasoline; however, there are greater emissions on the whole. All we're doing is moving the pollution from Milwaukee to Iowa.
The article contends that the whole ethanol issue is just welfare for Iowa farmers disguised as an environmental issue. I don't have a problem with welfare for farmers (Wisconsin does similar things for our dairy farmers), but don't call it something else and make a lot of pollution in the process. Just give them some money and be done with it.
I have the same problem with EVs. Unless you have some major solar/thermal/wind energy sources in your area, the electricity you're recharging with is very dirty.
