The minimum requirements for ethanol levels in the US are getting more difficult to reach because cars today getting better fuel economy.
With the 2016 US presidential election already getting rolling, the debate over the Renewable Fuel Standard could play role in farming-intense states. Iowa Governor Terry Branstad, a supporter of the mandate, thinks candidates who don't support the RFS could be at a disadvantage there for the very important caucuses.
The federal government mandates that a certain amount of ethanol be blended with gasoline. The price of corn-based ethanol hasn't been affected by the same anchor-drop in price as petroleum fuel, however, and along with that, the complicated mechanics of its pricing and trade are said to be what is keeping the price of gas from falling even further.
The Environmental Protection Agency (EPA) is not going to decide just yet how much biofuel to add to the national fuel supply in the future. Last year, the EPA said, for the first time ever, that it might reduce the biofuel component in American gas, but is now saying that the 2014 standards rule will be "significantly delayed."
Green transportation issues were not at the top of this year's midterm elections in the US, but the sweeping Republican victories – and probably new Senate Majority leader Mitch McConnell – could affect at least some aspects of how we get around without using as many resources as we used to.
November's coming up, so that must mean some election-season lobbying is on the way. One of the subjects being debated in the US right now is the how much renewable fuel must be included in the US gas supply. And advocates are already taking to the digital airwaves to make their point.
