So many choices for gasoline.

 “Corn ethanol is not a climate-friendly fuel,” said Dr. Tyler Lark, assistant scientist at University of Wisconsin-Madison Center for Sustainability and the Global Environment and lead author of the study.


The research, which was funded in part by the National Wildlife Federation and U.S. Department of Energy, found that ethanol is likely at least 24% more carbon-intensive than gasoline due to emissions resulting from land use changes to grow corn, along with processing and combustion.

I've always thought ethanol was not kind to the planet because of all the diesel fuel and chemicals needed to produce the crop and refine ethanol.
In hilly southern Iowa a lot of grassland was changed to crop ground when ethanol got big.
This added to water pollution problems from the added soil and chemical runoff. There's also less wildlife habitat.
