Since 2005, Congress has required oil refineries to add ethanol, mostly from corn, to their gasoline. It’s called the “Renewable Fuel Standard” (RFS). The EPA runs the program. In January, Reuters reported: “EPA will have to decide on the next phase of the program in coordination with the Department of Energy and the Department of Agriculture. The EPA plans to propose requirements… in May this year.”
Members of Congress should not leave the changing of RFS to some pointy-headed bureaucrat in the administrative state (i.e. the EPA) but should adjust the program themselves. And they should seriously consider ending the program. Or, they might consider an idea floated in “How To Fix The Ethanol Industry” by Robert Rapier at Forbes in 2019.
To understand just how wacky the RFS is, read “Stop the Ethanol Madness” by Mario Loyola, which ran at the Atlantic in November of 2019. Loyola explains how RFS is not only uneconomic but is also destroying the environment. Loyola asserts that “today’s corn-ethanol program is a glaring failure, and it is unconscionable that politicians of both parties are conspiring to keep it alive despite knowing full well what its problems are.”
Ethanol has about one-third less energy than does gasoline. So cars using ethanol get fewer miles per gallon. Flex-fuel vehicles that use E85 get up to 27 percent fewer miles per gallon.
A huge problem with corn ethanol as a fuel for ICE (internal combustion engines) is its EROI, i.e. its energy return on investment. EROI is the amount of energy produced against the amount of energy used to produce it. The formula for EROI is the energy output divided by the energy input. An EROI of 1.0 would mean that you’re expending as much
energy to produce energy as the energy being produced, so it’s would be a wash, a draw, and utter folly to produce energy with such a low EROI. Corn ethanol has an EROI of 1.5 as compared to gasoline’s 11. Because of corn ethanol’s low EROI, you’re basically swapping one type of energy for another. How smart is that?
