The politics of the Renewable Fuel Standard (RFS) and its mandates for ever-increasing ethanol use are on display this weekend in Iowa, a key presidential primary state. Nothing against Iowa – or ethanol, for that matter – but the RFS illustrates that when you mix energy policy and politics bad public policy can result.
Certainly, the RFS shows the difficulty of trying to apply central planning to the marketplace, of trying to mandate consumer behavior. The RFS is a relic of the era of energy scarcity in the U.S. whose best intentions have been superseded by surging domestic oil and natural gas production.
Still, the RFS remains and along with it potential risks to the economy, vehicle engines and more. It also risks unintended consequences, including a moral/ethical dilemma over whether food should be turned into fuels, as well as concern for the environmental impact of corn ethanol production.

Let’s update an informative chart that’s critical in the continuing discussion of E15 fuel and the ethanol mandates of the Renewable Fuel Standard (RFS).
It lists, by vehicle manufacturers and model years, whether a specific manufacturer recommends operation of its vehicles on E15, which contains 50 percent more ethanol than the E10 fuel that’s prevalent across the country. We’ve posted the manufacturers/model years grid a number of times (including here and here), but this chart s updated to include the 2015 model year.

The Renewable Fuel Standard (RFS) and its mandates for increasing use of ethanol continue to be debated publicly – in Congress, where lawmakers could vote to repeal the dysfunctional program and in places like Chicago, where service stations could be forced to carry higher-ethanol blend E15 fuel.
The Fill Up On Facts website is a great resource on the RFS, ethanol mandates and related issues. Information is available on the RFS itself, as well as problems that have made the program and its ethanol mandates untenable – like the refining “blend wall,” potential risks to vehicle and equipment engines and impacts on food prices.

A new peer-reviewed study of transportation fueling options generated a pretty good buzz last week, basically for the finding that electric vehicles might not be as good for the environment as previously thought. Another of the study’s conclusions also is worth underscoring: the negative environmental impacts of corn ethanol in fuels.
A team of University of Minnesota researchers assessed life-cycle air quality impacts of 10 alternatives to conventional gasoline vehicles. On corn ethanol:
We find that powering vehicles with corn ethanol or with coal-based or “grid average” electricity increases monetized environmental health impacts by 80% or more relative to using conventional gasoline.

Chicago Mayor Rahm Emanuel and his allies on the city council deserve credit for putting a stop – for now at least – to an ill-conceived proposal that would mandate the sale of higher ethanol blend E15 fuel at city service stations.
We say ill-conceived because, as argued here and here earlier this year, the E15 requirement could be full of risk for consumers and small business owners – while mainly benefiting ethanol producers. Recently, AAA urged Chicago lawmakers to vote against the ordinance.
