Getting back to the outcry on ethanol mandates, however, it's been a case of "facts! we don' need no damn facts!" amongst the chattering class.
"Now, damn you, stop all this corn ethanol foolishness, immediately!"
The politicians are already saying it.
Well,
I've lived long enough to learn that the Conventional Wisdom is almost
always wrong. That rule is particularly applicable when the CW
cheering section is led by the New York Times, Hugo Chavez, the UN, and
environmental activists.
It's surprising, however, and particularly disturbing to me that fairly large
numbers of conservative commentators, bloggers, etc. are also jumping on the NYT/UN/Chavez/GreenPeace
bandwagon to condemn corn ethanol production as an evil enterprise.
The bandwagon travelers are not your typical conservative bedmates. But
the thing is, many of these misguided conservatives are so into bashing
anything that is led or driven by governmental action - as are the corn ethanol
mandates - that they are now acting in knee-jerk fashion without considering the
underlying fundamentals of what is happening right now ... in both the energy
markets and the food markets, and indeed in commodities markets in general.
The anti-ethanol myth-making has been going on for a very long time on the
right side of the political spectrum, of course, because governmental support
for ethanol production has been - in the estimation of many observers - fatally joined at the hip with America's flawed
farm subsidy programs which continue to get more and more bloated and
disconnected with good public policy - all done in the search for Midwestern
farm state votes in the quadrennial Presidential primaries. Certainly
there is good reason to question almost any aspect of current American farm products
price support programs, but unfortunately, the myths of corn ethanol production are legion
and almost entirely false and/or misleading.
Here's some examples of the corn ethanol myths:
- It takes more energy to make corn ethanol than it delivers, so it
actually makes America
more dependent upon imported oil
- Corn ethanol is subsidized by the Federal Government
- Corn ethanol is sucking up too much of the US corn crop, which reduces worldwide food
production, leading to the current worldwide food crisis that is
unconscionably starving little children in Africa and Asia
.... therefore corn ethanol production is immoral!
- There is so much demand for corn for ethanol that farmers are
willy-nilly converting wheat and rice fields to corn crops, thus further
reducing world food supplies of other grains
- Corn ethanol pollutes the air more than petroleum fuels do
- Corn ethanol is bad for your car and reduces your fuel mileage
- Why bother with corn ethanol, when non-corn ethanol is a better
substitute for oil
This topic could easily
become the subject of a book-length dissertation. That's not what this blog is supposed to be ... but
nevertheless, let me address each one of the myths above, providing a few key
links so that you can go forth and read some of what I describe for
yourself. Then you can decide whether
you believe the headlines and the politicians and the talking heads and
bloggers, or not.
Myth No. 1: "It
takes more energy to make corn ethanol than it delivers, so it actually makes America more dependent upon imported oil."
This myth is simply not
true, but at one time, decades ago, it may
have been true for a short period of time.
Back in the 70s, during early R&D on corn ethanol production, which
came in response to the first OPEC oil embargo, the inefficiencies entailed in
growing corn, transporting it for processing, and producing the fuel itself
rendered the "net energy gain" (NEG) of corn ethanol to less than one ...
meaning, it required more fuel (in terms energy content, as measured in British
Thermal Units, or BTU, to produce corn ethanol than it yielded as a liquid
fuel.
But lo and behold, it's
now thirty some years later, and like virtually everything else in our
technology and productivity-driven world, the efficiencies in both corn
production and fuel processing have increased greatly. Farmers finally acquired and aggressively
used computer information technology in the 90s, and researchers developed genetically
engineered corn varieties for the first time in history. By the mid-1990s, NEGs for corn ethanol
were being reported in the net positive range, about 1.24 to 1. By 2004, with increasing crop yields, better
energy efficiency in fuel production, an increasing number of corn ethanol
plants (reducing the distance corn needed to be hauled for processing), the USDA and Argonne
National Laboratory in 2002 reviewed all the recent studies on corn ethanol and
reported an NEG 1.34 to 1, based upon all energy inputs, and an even higher
6.34 to 1 based upon imported liquid petroleum fuel inputs. The increase in NEG for corn ethanol has
continued to increase since 2002, with ethanol
producers reporting in 2004 that in just the previous five years (1999-2004),
ethanol plants on average had increased their ethanol yield per bushel of corn
by 15%, and reduced their energy consumption per bushel by 20%. Such improvements continue today, four years
later. Farmers today also use more efficient
farming practices (fertilization, insect controls, irrigation, etc.) and better corn hybrids that require less of all of the above, thus reducing the total energy required to produce a bushel of corn.
Myth No. 2: "Corn
ethanol is subsidized by the Federal Government"
This myth is partially
true (at the "top line"), and yet at the "bottom line", it isn't. Well, yes, corn
farmers - make that ALL corn farmers, not just the ones who grow corn for ethanol - enjoy the financial benefits of Federal agricultural price support
programs, just as do most other US farmers who produce favored ag commodities like wheat, rice, sugar, peanuts, and dairy products. But ethanol-destined corn is not subsidized differently from feed corn or Cap'n Crunch corn. Corn ethanol producers do, however, receive a 51-cent per gallon production subsidy.
However, the inter-workings of these two subsidies are not as simple as they may appear. If the corn ethanol production subsidy boosts the demand for corn (as it does), then corn prices naturally tend to rise (as they are doing now). When corn prices rise, then the money paid to corn growers in the form of governmet price supports (to keep prices above a target price) then goes down. The net effect of these two subsidies - i.e., those subsidies paid to corn growers plus those paid to corn ethanol processors can be - as it was in 2007/2008 - a net reduction in crop subsidies paid.
Gee - an intelligent government program! What a concept!
Total corn ethanol subsidies paid in 2007/08 totaled about $3 billion, but total corn crop subsidies paid out decreased by $6 billion from the year before, meaning the corn ethanol production subsidy paid for itself by a factor of two times.
Plus, on top of a net reduction in corn subsidy payments, the rising price of corn coupled with the 6% increase in corn exports created a net $20 billion improvement in the US trade deficit in 2007.
Even better, with a virtually long term guaranteed rise in corn demand, the reduction in corn price support subsidies is likely to continue indefinitely, more or less permanently reducing taxpayer-paid corn subsidies in the US.
What's not to like about that?
In truth, most
corn-ethanol naysayers continue to untruthfully blast corn ethanol as a government
subsidized boondoggle.
The other form of government support to corn ethanol production is the ethanol mandates in the 2005 and 2007 energy legislation as enacted. But a mandate to produce ethanol is not a
subsidy - it is only a virtually unenforceable statement of government
intentions and policy. The mandates do not
have any mechanism for forcing individual corn farmers to sell their crops to ethanol
producers. The mandates do not force
individual investors to pony up capital to build corn ethanol plants. What the mandates do is to create a market,
which is, above all else, a psychological mindset, that yes, indeed, there will
be a market for your product if you grow more corn, or if you invest in a corn
ethanol plant.
In fact, the previous corn ethanol mandate in the 2005 energy bill worked so well that the mandated 2012 production of 7.5 billion gallons will be achieved this year - in 2008. It's clear that the marketplace responded much better than the architects of the 2005 legislation envisioned. Of course, the fact that OPEC continues to oblige the corn ethanol industry with artificially-low production rates in the face of record oil prices only hastens the response of the free market.
Myth No. 3: "Corn
ethanol is sucking up too much of the US corn crop, which reduces worldwide
food production, leading to the current worldwide food crisis that is
unconscionably starving little children in Africa and Asia .... therefore corn
ethanol production is immoral!"
Well,
well, where do I begin, there's so much bunk to debunk here ... including the critics' misunderstanding of food
production and food use, as well as silly moralizing.
First of all, US corn exports - as I point out above - increased last year. How does that little fact comport with the argument that corn ethanol is depriving little kids of their corn?
Second of all, even if the US corn exports didn't increase - which they did - most of the world's poor who
are in danger of starvation have subsistence diets based upon non-corn grains,
principally rice and wheat, which have been the staple foods of European,
African, and Asian peoples for many thousands of years. Corn was only discovered in the New World by European conquistadors (well, actually, the native Americans discovered and cultivated corn, and the Euros discovered the Americans) a mere 500 years ago, which then was introduced
throughout the "old world", where corn or "maize" met varying levels of
acceptance. Today wheat and rice are the
dominant food grains for most of the world's poor. The principal
reason that US corn is used
to feed starving people is a US
law that requires that all foreign food aid be purchased from US growers,
rather than from local or regional sources.
So whenever there is a local or regional food shortage, the net effect
is that US aid wipes out the
market for local or regional grain growers, whose farmers cannot compete with
"free" US
corn. This is a misguided policy on its
own merit.
Secondly,
most US
corn is grown not for direct consumption by humans, but is raised and consumed
as dried "field corn". That
field corn is used mostly as livestock feed for domestic cattle, hogs,
chickens, and such - and in any case, the world's starving poor never could afford to buy
imported American beef, pork, or chicken.
Similarly, aside from corn ethanol production, the next largest use of
American corn is for corn syrup production - so that we can sweeten our soda
pop, confectionaries, breakfast cereals, etc.
So
if someone insists on making a moral argument against corn ethanol production,
they're aiming at the wrong target.
Is it less moral to grow corn for US vehicle fuels, depriving OPEC-funded terrorist thugs (Al Qaeda, Hamas, Hezbollah, the Taliban, and Al Quds) of
American dollars that they use to fund the wanton slaughter
of tens of thousands of innocent civilians, women, children, and the elderly ... than it is to use the same corn to
grow sweeteners for your kid's (or your?) Cap'N Crunch in the morning?
You
see how silly it gets! You cannot impose
moral objectives on a free market, without making it an unfree market very
quickly, and without at the same time getting tied up in so many moral knots as to make
the entire enterprise self-defeating.
Leave the moralizing to the pulpit and the UN General Assembly. Leave the free markets to the free markets!
Myth No. 4: "There is so much demand for corn for ethanol that
farmers are willy-nilly converting wheat and rice fields to corn crops, thus
further reducing world food supplies of other grains."
Contrary to what this
argument says, there is no lack of productive farm ground in America. In fact, as many of us realize, the US government
pays American farmers to not grow food crops, in order to keep food commodity
prices high under our ag price support laws.
Also, this argument ignores the fact that while US corn production is
increasing to meet the new demand for corn ethanol, according to
the USDA, US production of wheat, rice, barley, and other crops is also rising,
with US wheat production increasing in 2007 by 14%, and US rice production
increasing by about 2%. The USDA also
projects that, even with increasing corn ethanol production, US corn exports are
projected to remain flat and then gradually increase over the next 7 years.
And why is production of
these other crops increasing? Because
worldwide demand and prices are high.
Which means that US
agricultural production is an example of an elastic supply and demand marketplace -
when demand goes up, prices go up, and production soon follows upward as
well. There is no lack of US
farm production capability that is constraining our ability to meet market
demands.
Myth No. 5: "Corn
ethanol pollutes the air more than petroleum fuels do."
I know some headline-grabbing
researchers are out there peddling this myth, but even
the Natural Resources Defense council is disputing one such study. But the fact is, when
ethanol used as an additive in gasoline at the typical E-10 rate (10% by
volume), the net effect is a reduction in numerous categories of regulated air
pollutants, including particulates, carbon monoxide, toxic hydrocarbons such as
benzene, and ozone (through reductions in ozone precursors in gasoline - i.e., volatile
organic compounds and carbon monoxide).
Myth No. 6: "Corn
ethanol is bad for your car and reduces your fuel mileage."
Now it's true that ethanol
has a lower energy content, as measured in BTU, as compared to gasoline (about
76,000 BTU/gal for ethanol vs. a seasonally-variable 108,000 to 117,000 BTU/gal
for gasoline). So naturally running on
pure ethanol will reduce the miles per gallon yield from what gasoline
typically produces in your car. But most
cars will not run safely on pure ethanol, or even on the commercially-available E-85 blend (85%
ethanol/15% gasoline). Only certified
"flex fuel" vehicles - of which only a very few exist, and only a very few (but growing number) are
being produced today - can safely burn E-85.
However, virtually all gasoline-engine vehicles run safely and
efficiently on E-10 (10% ethanol/90% gasoline), and this fuel is now readily
available, and will become more available as the ethanol supply increases. The
EPA has found that the typical E-10 "reformulated gas" fuel, or
"RFG" (10% ethanol and/or other oxygenates such as MTBE or ETBE/90%
gasoline) yields a total reduction in fuel mileage of only 1% to 3% in typical
vehicles. In fact, the EPA says the
difference in fuel BTU content between typical winter blend and summer blend
gasoline is larger than the difference in BTU content between E-10 and pure
gasoline. And the EPA says this
reduction is virtually unnoticeable to most drivers, for whom other factors
(i.e., the way they drive their cars, tire pressure, vehicle maintenance, etc.)
tend to have much larger effects on the vehicle fuel mileage that actual
drivers obtain. In any case, EPA requires
oxygenates for gasoline anyway - whether it is MTBE (now outlawed due to
concerns over water pollution), ETBE, or ethanol. So the bottom line is if you use E-10 you
will not notice any significant change in your fuel mileage from "pure
gasoline" (which isn't pure gasoline in any case).
Myth No. 7: "Why
bother with corn ethanol, when non-corn ethanol is a better substitute for
oil?"
This isn't really a myth
as much as it is an excuse for doing nothing about American energy
independence. Sure, it is fairly well
known now that cellulosic based ethanol has a much higher NEG than does corn
ethanol (about 5 to 1 vs. 1.34 to 1), and for that reason, the 2007 energy bill
mandated, for the first time, a non-corn ethanol production mandate that, by
2022, will exceed the corn ethanol mandate in that same year (21 billion gal.
vs. 15 billion gal.). But the problem
is, the cellulosic ethanol production cycle has not yet been commercialized at
full scale, whereas corn ethanol has been commercially produced for decades,
and has become very dominant and well understood in the last ten years in
particular. So the cellulosic ethanol
industry, while I have every confidence it will prove feasible, effective, and
efficient, is still a few years off. In
the meantime, we still need to replace foreign oil with home-grown fuel, and
for that, corn ethanol is the "bird in hand" that always beats the
"bird in the bush". By all
means, lets develop a cellulosic ethanol industry in America. Let's do biodiesel too, along with wind
energy, photovoltaic, and the holy grail of alternative energy production:
nuclear fusion. But we have corn
ethanol, so let's use it, while we work on fixing the bugs (in some cases,
literally!) in those other sources so that altogether, we can completely wean
ourselves from those OPEC guys who are taking large amounts of our money and
sometimes using it for very nefarious purposes.
Whew!
This may not have been a
dissertation, but it's been plenty long enough.
Yet there's a great deal
more to examine, discuss, and consider in the world of energy ... some of this
other stuff is frankly much more exciting to ponder than corn ethanol.
