For the past few months, I have been hearing a lot about how great ethanol is and how it can save the world. However, the more I research it, the more I worry that we aren’t creating more problems than we are fixing. A recent post over at The Browser provides a link to a recent article (requires PDF) that studied the affects of ethanol in greater detail. Initial indications are that the ozone health risk for E85 is worse than gasoline, potentially making populated areas more polluted. However, with emission regulation, E85 could better than gasoline. We can only hope that E85 emission regulations are introduced soon.
