Too Corny

Written by Stefanie on June 8, 2008 – 11:11 am - Add your Comment »


Sounds like the popular Corny Ethanol Solution is not so good good good. after all! Below find excerpts from articles I have gathered on the subject.

From: http://www.motherjones.com/news/outfront/2007/11/the-ethanol-effect.html
Everything about ethanol is good, good, good,” crows Iowa Senator Chuck Grassley, echoing the conventional wisdom that corn-based ethanol will help us kick the oil habit, line the pockets of farmers, and usher in a new era of guilt-free motoring. But despite the wishes of Iowans (and the candidates courting them) the “dot-corn bubble” is too good to be true.

Excerpts from http://www.gimme-five.com/2007/06/ethanol-is-bad-ethanol-from-corn-is-worse

I wrote an article a while ago about the downsides of producing ethanol as a transportation fuel. These downsides, in short, are:

  • Ethanol has a negative energy balance. Ethanol from corn, switchgrass, and wood biomass requires 29%, 50%, and 57% more energy, respectively, to create the ethanol than the energy contained within the fuel.
  • Because ethanol production requires a significant amount of energy, and most energy in the US is produced from coal, the small reduction in CO2 and other polluting emissions from burning ethanol versus gasoline will be more than offset by the power needed to produce the ethanol.
  • Ethanol crops have a notoriously low energy yield per hectare. Thus, it requires a large amount of land to produce a meaningful amount of ethanol. Last year, 20% of the total corn crop was used to produce ethanol, and it offset only 1% of US oil use.

I still don’t believe that switchgrass-based or any type of ethanol will be the transportation fuel of the future. Switchgrass may not be as bad as corn, but the technology needs to dramatically improve before it is a viable option.

Another interesting point is that plants capture something like 0.1% of the sun’s energy, whereas photovoltaics capture around 10%. This really makes me feel that electric vehicles, once batteries are developed further, could make a huge difference in reducing our oil dependence.

I agree that ethanol from sugarcane is more efficient than corn. However, the US can’t emulate Brazil’s ethanol success because of two factors. First, to grow sugarcane, a warm climate is needed, and much of the US is too cold to grow it. Secondly, Brazil’s total fuel demand is very small compared to the US in per capita and aggregate terms, so much less land is needed to grow fuel. US Transportation fuel demand is huge in both aggregate and per capita terms.

Logical Science

Many ethanol critics will point to a study performed by Berkeley’s Tad Patzek and Cornell’s David Pimentel which says corn ethanol requires 29 percent more fossil energy than what you can get out of it… Yet the USDA reports say ethanol is a net energy gain. Why the discrepancy? Well to make a long story short the USDA is doing some fancy accounting with by-products. The widely referenced chemical engineer Robert Rapier says: “The only way the energy balance gets into positive territory is that by-product credit.” This by-product credit is plant matter that is processed into makeshift animal feed.

The calories are counted as fuel energy and added on top of the ethanol that is produced. Without this animal feed corn based ethanol is a net loss of energy. If you add this animal feed in you get into the positive but the amount of gain is not very significant.

Food Crisis Largely Due to Biofuel Production

Posted on: Wednesday, 30 April 2008, 10:40 CDT

A group of food scientists called for a reconsideration of plans to use foods such as corn and soybeans for biofuels….

Joachim von Braun, Director General at the International Food Policy Research Institute in Washington, the policy arm of CGIAR, said that more research should be done on developing non-grain crops, such as switchgrass, into biofuel.

He added that the United States and other countries have to make a hard choice between fighting high fuel prices and fighting world hunger.

U.S. eyes shift away from corn ethanol

Chicago - America’s love affair with corn-based ethanol is cooling – at least in Washington.

Some legislators blame the rising use of corn as a biofuel as a key factor behind high food prices. Others want to freeze the federal mandate on biofuels production at current levels, reversing legislation passed just a few months ago that increases it through 2022. Still others are pushing to shift tax incentives away from corn-based to cellulose-based ethanol in the nearly completed farm bill.

These moves represent a dramatic backlash against corn ethanol, which until a few months ago was widely viewed as a boon for both farmers and consumers.

Alternatives to shopping at Whole Foods

Written by Stefanie on May 21, 2008 – 8:44 am - 6 Comments »


Fresh Organic ProduceI have often written to keep it organic whenever possible. I have always had easy access to fresh organic foods, but many of my readers might ask - Where do I get organic produce? Health food stores are but one option. Like many, I have a love/hate relationship with Whole Foods Market. They are just so expensive! I shop at Farmers Markets whenever I can. But there is one more option.

If you are lucky enough to live in certain cities, you can have organic produce delivered to you on a weekly or bi-weekly basis. An additional benefit is that this produce is usually fairly local and in season. Try getting that from any grocery store! The fresher the produce, the longer it lasts. I have focused here on local delivery.

I found a lot of good links and info at www.greenpeople.org

The Importance of Breakfast (Weight! Don’t tell me!)

Written by Stefanie on May 12, 2008 – 12:37 pm - Add your Comment »


raw recipes breakfast
Breakfast is the most important meal of the day. Breakfast is the first chance the body has to refuel its glucose levels, also known as blood sugar, after eight to 12 hours without a meal or snack. Glucose is essential for the brain and is the main energy source. People who do not take breakfast are going to have lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration. (from http://www.healthmad.com)

The first thing many people do when they want to lose a little weight is to skip breakfast and skimp on lunch. Then they go crazy at night and chow down with too little time left to metabolize those calories before sleep. Skipping breakfast causes the body to go into a “starvation mode” which slows the metabolism, contributing to weight gain.

The American Dietetic Association says breakfast is the most important meal of the day.Despite the healthful benefits, breakfast may be the meal that is most often neglected or skipped. Eating breakfast not only aids in weight management, it fuels the body to help provide energy, better concentration and problem-solving ability throughout the day, according to the food and nutrition experts at the American Dietetic Association.

Forty years of breakfast related studies show that jump starting the day with breakfast benefits everyone — children, teens and adults. “Eating breakfast is very important for the brain and the body first thing in the morning”, said Los Angeles registered dietitian Gail Frank, spokesperson for the American Dietetic Association. “Breakfast skippers often feel tired, restless or irritable in the morning.” (http://www.bellybytes.com/articles/breakfast2.shtml)

If you want to maintain a good weight, the first thing to do, is to adjust the “when” of your eating rather than the “what.” Of course you want to eat healthier foods, but many people try to eat better while continuing bad habits about WHEN they eat. Changing the “what” often needs to be addressed with patience and study, so get going with this simple when approach right off the bat and you will be in better shape for the long haul.

Of course there are some breakfasts that are healthier than others, but the important first step is to eat one!
