Ethanol has done nothing to reduce dependence on foreign oil, is bad for engines, polllutes the air and damages pipelines. Moreover, in arid western states it demands water that they don’t have if they attempt to produce it locally, which, because of what it does to pipelines, is required. Moreover, the excessive growing of field corn for ethanol pointlessly increases the harmful run off of good topsoil. Other than that it’s just great. And by the way it reduces engine power output.
