There are so many economic variables that come into play when determining fuel prices, including subsidies and multiple incentives of one kind or another, that the energy cost of producing something is not typically, or at least proportionally, reflective of what its ultimate price will be. This doesn't even take into account the price elasticity of the demand for the product.

When we were running our plant, we were constantly communicating with other ethanol producers about what different processes worked and which didn't. You are spot on in your assessment that production techniques will get more efficient. In the few years that I was there, we improved the efficiency of the ethanol drying process by 300% over traditional drying processes . . . and this was almost 20 years ago.

For example, is the CO2 produced in ethanol production used or vented to the atmosphere? Is the carbon released as CO or CO2, or is it released as soot?
