Harnessing Ag’s Energizer Bunny

Put a plug on a hybrid car and give it flex-fuel capabilities and you will have David Morris’ dream-solution to our oil woes. This weekend, the Vice President of the Institute for Local Self Reliance spoke at the Alternative Energy Resource Organization’s (AERO) annual meeting, and argued that this kind of car will best utilize the current centralized electric grid system. A larger battery would give it the capacity to go further on less fuel. And flex-fuel would increase efficiency even more because it would allow the car to travel on gas or ethanol.
Ethanol can be derived from corn or other plants such as switchgrass, wood or shrubs, but corn is most common because it is easier and currently cheaper to produce. Regardless of the plant matter, enzymes are used to digest the material and turn it into alcohol – the kind that can fuel an engine but not get you drunk.
The plug-in flex car is just one part of what Morris has termed the, “Carbohydrate Economy,” based on the use of plants for fuel, chemicals, textiles, paper and the materials we live by. According to Morris, this car would tap into the current electrical grid systems at night and during off-peak hours. While there are issues with the way power is gathered, he argues that even coal-fired plants have less pollution than the oil we use to power our cars. Corn ethanol would provide the fuel and a new source of income for struggling farmers.
But farmers would not just produce the ethanol. Most of their new income would come from a shared ownership of ethanol refineries. This local ownership can reinvigorate local economies and provide direct income for farmers, and the idea has garnered support in the west as a means for farmers to diversify, including an operation in Malta Bend, Montana.
But this ownership has been complicated by government policies. While 50 percent of ethanol refineries were owned by farmers in 2003, around 80 percent of new ethanol production comes from absentee owned plants. For Morris, policy changes should be made at the federal and state level to support locally owned refinery development and corn growers.
Morris is not alone in his thinking. Ethanol became a media darling this year when D.C. politicians saw corn as an anathema for energy woes. Recently, candidates have been stumping through Iowa with various plans for a new corn-fed economy that will support farmers and garner votes. Senator John Thane of South Dakota asked NASCAR to “Race on Ethanol,” and “Win for America.” Even the President oil-man from Texas, has committed the United States to produce 35 billion gallons of ethanol by 2017.
But proponents selling the economic possibilities of ethanol often overlook what critics have long argued are the major, untenable fall-backs of the fuel.
In the July issue of Rolling Stone, Jeff Goodell revealed that ethanol production currently provides a mere 3.5 percent of our gas needs, and producing that amount uses 20 percent of the U.S. corn crop. This statistic is even more telling than the energy gain ratios being thrown around in regard to corn based fuel.
When the energy for fertilizers and fuel used to grow corn are taken into account, and compared to the energy ethanol produces, the “energy balance” is as low as 1.3 to 1 or, as Morris argues, can be higher than 2 to 1. In comparison, Brazilian ethanol produced from sugar cane has a ratio of 8:1.
The environmental implications of corn production are even broader. The ecological devastation of industrial-corn production can be seen in the dead zone of the Gulf of Mexico where silt and fertilizers from farms upstream collect and deplete the water of oxygen, and kill most marine life. It is also possible that burning ethanol in our cars reduces emissions at the tailpipe by less than 15 percent.
And as farmers commit themselves to grow more corn to fuel our cars there could be less to fuel our bodies. Economists from the University of Minnesota have argued that the increase in corn ethanol will lead to higher food prices with devastating impacts for those who live in poverty. It is also a misuse of food. Filing the tank of one SUV with pure ethanol would take 450 pounds of corn. That much corn would provide enough calories to feed a person for a year.
For farmers around the west who have watched corn prices double in the last two years, David Morris speaks a flex-fuel language that is also fueling some current viability. But economically speaking, ethanol may not be the thing that will sustain farmers…even if they own the ethanol production plant.
The International Institute for Sustainable Development found that ethanol subsidies amount to as much as $1.38 per gallon—about half of ethanol’s market price. This is a high price for a fuel that would only replace 12 percent of current gasoline use even if all of the US corn crop were devoted to its production.
Subsequently, the economists from the University of Minnesota argue that U.S. policy should not focus on providing the economic incentives for ethanol production that Morris encourages. Rather, the government must commit to increasing energy efficiency and devote financial resources to cellulose based ethanol rather than corn.
While the Energy Department has planned to spend $385 million on six biorefineries dedicated to cellulosic ethanol, processing the fuel made from cane sugar, grasses, shrubs or agricultural wastes remains prohibitively expensive.
Even so, Bush was also hopeful about cellulosic ethanol in his State of the Union address this year. “We’re very close to a breakthrough where we’ll be able to figure out how to make ethanol from other forms, other materials, like grasses, woods…All of a sudden, we may be in the energy business by being able to grow grass on the ranch—and have it harvested and converted into energy…We’re told that if we continue to focus on research, we’ll be able to, within six years, have a competitive fuel to gasoline.”
But before the excited President retires to his ranch in Texas to become a cellulosic ethanol farmer, he will need to realize that the costs of harvesting, transporting,and converting cellulose-based ethanol means that it is also not commercially viable. He will also need to contend with a powerful corn lobby that wants to see King Corn in our fuel tanks.

First, the alcohol produced to fuel your car is indeed the same alcohol you can enjoy (in moderation, of course) in an adult beverage. The only difference is that , by law, it must be de-natured with a small amount of gasoline or other denaturant to make it unfit to drink.
Second, economists have been breathlessly predicting higher food prices as a results of corn-to-ethanol produciton and it just hasn't happened, nor will it, in my estimation. The corn used to make ethanol is used only indirectly as food for humans - as feed for livestock. Most people don't know this, but only the starch portion of corn is used to make ethanol and every bit of the protein in the corn (the stuff cows like to eat) remains behind and is dried into a product called distillers grains, which makes a great food source for cows and pigs and turkeys. As ethanol prduction increases, the supply of distillers grains increases, too.
And, if the reporter is going to talk about subsidies, I'd also ask her to investigate just how heavily the oil industry is subsidized by the American taxpayer. Not sure why almost no one talks about it - we've subsidized them to the tune of billions of dollars a year since the beginning of the last century through special tax breaks, oil depletion allowances, cheap drilling rights on public (your) land - not to mention the billions and billions of dollars and the incalculable cost in human lives spent trying to ensure the security of the precious oil that from countries that don't like us very much.
Finally, most corn growers I know aren't as committed to growing corn as they are to making a living. If soybean prices are good, they plant soybeans. If corn prices are good, they plant corn. If there is a way to make money growing switch grass or parsnips for that matter, to make ethanol, they will. Problem is, making it a viable option to do so takes a lot of research and a lot of money.

Ethanol Demand Threatens Food Prices
Rising corn prices are already affecting everything from the cost of tortillas in Mexico City to the cost of producing eggs in the United States.
The focus needs to be less consumerism. We should not just be replacing needs of gasoline; we should also be focusing on using less.
I've just registered at the forum. This is my first message.
Please don't become angry about me.
Thank you.
As for blaming ethanol demand for the rising price of groceries, beer, torillas, tequila, you name it - has anyone noticed the cost of a barrel of crude is up something like 60 percent? Hello? Is the stranglehold of oil on our culture so complete we don;t see it anymore?
On average, actual food input costs of final grocery products are in the neighborhood of 18 percent. The other 82 percent is labor, transportaiton, packaging, marketing - NOT the actual food product.
The environmental and economic harms caused by subsidized corn production to feed the ethanol scam are so well established that only those on the payroll of the renewable fuels cabal can suggest otherwise.
One of the consequences of government mandating the production of 7.5 billion gallons of ethanol by 2012 (the senate energy bill seeks to increase this mandate to 35 million gallons) is the reticence of oil companies expanding their refining capacity.
...as opposed to the environmental and economic harm caused by subsidized oil production? I'd remind you of oil spills around the world (at least one of which from 20 plus years ago they're still trying to weasel out of paying for in Alaska), suspected cancer causing gas additives like MTBE seeping into groundwater, special tax breaks, oil depletion allowances, cheap drilling rights on taxpayers' land - not to mention the enormous cost in dollars and lives of keeping all that precious oil secure in areas of the world filled with people who don't like us much.
And, if oil companies will be so reticent to expand their refining capacity if there is a higher renewable fuel standard, tell me, why is it that the last refinery built in this country was in Louisiana in 1976? Not a lot of ethanol being produced back then.
Give me a break.
I'm not in favor of oil subsidies.
I've not checked the data but my bet is in 1976 demand forecast for gasoline did not justify the capital investment to expand refining capacity.
http://www.boston.com/business/globe/articles/2007/06/18/biofuel_push_may_keep_gas_prices_high/
WASHINGTON -- A push from Congress and the White House for huge increases in biofuels, such as ethanol, is prompting the oil industry to scale back its plans for refinery expansions. That could keep gasoline prices high, possibly for years to come.
With President Bush calling for a 20 percent drop in gasoline use and the Senate now debating legislation for huge increases in ethanol production, oil companies see growing uncertainty about future gasoline demand and little need to expand refineries or build new ones.

When it comes to navigating a way out of the nation's energy crisis, you have to wonder whether the fix is already in.
The government has picked the winner--even as senior policy makers issue bland pronouncements about finding new technologies to help break our energy dependence on foreign oil. Between now and 2012, biofuel subsidies will total more than $92 billion, according to a recent report conducted under the auspices of the Global Subsidiaries Initiative.
The timing is coincidental, but the report came out just as Senate and House leaders were weighing a plan which would leave renewable energy out of the next congressional energy bill.
I'm sure there's some larger logic to explain that omission. But it might have a little something to do with the political muscle of the farm interests, a powerful lobby that knows its way around the corridors of power.
The 2007 farm bill features strong support for biofuel subsidies--even with crude oil prices hovering over $90 a barrel.
