Letter: Water and ethanol

Mr. Lefever, in your June 4 guest opinion, you conveniently forgot one very important tidbit of information in your biased push for ethanol: How much water does it take to produce one gallon of ethanol?

I’m all about the concept of ethanol as an alternative fuel. However, as a Colorado resident, I fully understand that our water is our gold. Conducting a quick, simple search, depending on which resource is referenced (bias noted in each) it takes anywhere from 75 gallons (Colorado Springs Gazette, Sept. 22, 2013) to 1,200 gallons (Wall Street Journal, Oct. 17, 2007) of water to produce a gallon of ethanol through the entire process, from planting until finished product.

Other sources reference only a 3.5 gallon-to-1 gallon ratio during production of the ethanol. The question I have not yet found the answer to is how much fuel is consumed by a combine and truck to harvest the corn and get it to the ethanol plant to produce each gallon of fuel.

I don’t know which numbers to trust, but the fact that you left this controversial data out of your article speaks volumes. Please note, I’m not trying to demonize ethanol. As a schoolteacher, I simply like to make sure all sides (bias noted) are presented so everyone can make informed decisions.
