Life without Oil
Goes over the pros and cons of alternative sources and starts with bio-diesel.

<font size="2" face="Verdana, Helvetica, sans-serif">Truly pathetic. Despite modern engines and drivetrains, average fuel efficiency is less than 15 years ago. Why? Because people think they need a 6,000 lb tank to drive to work in. Pathetic. Perhaps they think that some of that 6,000 lb might somehow get into their penis and make it bigger?After all, largely because of the popularity of gas-guzzling sport utility vehicles, the average fuel economy of the 2003 fleet of cars sank 6 percent below the peak set 15 years ago.
<font size="2" face="Verdana, Helvetica, sans-serif">What a load of cr*p. "Unquestionably the most promising alternative fuel"? Bush and the oil/coal companies certainly have done a masterful job of deluding the public into thinking that this "hydrogen economy" is going to save us. This ignorant "hydrogen is everywhere, and when used to power a... fuel cell, its only waste product is water". Sure, hydrogen is everywhere - attached to other atoms - in molecules of water, fossil fuels, etc.. The hydrogen has to be separated to be used. If you use water, you expend more energy in electrolyzing the water and storing/shipping the hydrogen than you get back out of the fuel cell. That energy used has to come from somewhere - and as long as most of our electricity is coming from fossil fuels, that's where it's going to come from, and it's going to still emit a heck of a lot of greenhouse gases and other pollutants in the process of getting that hydrogen. Use gasoline or natural gas? Still emits lots of greenhouse gases.In his so-called FreedomFUEL initiative, the president zeroed in on what is unquestionably the most promising alternative fuel. Hydrogen is everywhere, and when used to power a special battery called a fuel cell, its only waste product is water.
<font size="2" face="Verdana, Helvetica, sans-serif">Natural gas is not clean - it still emits CO2 (unless the natural gas is actually made from biomass, in which case there is no net CO2 emissions. But, the vast majority of natural gas used in the US is fossil fuel in origin). In fact, most of the methanol used to make biodiesel comes from natural gas - which is why most biodiesel only reduces CO2 emissions by 78% - the vegetable oil components has no net CO2 emission, but the methanol (from natural gas) does. Methanol, like natural gas, can be made from biomass. But, there's very little emphasis on going that route unfortunately.Until renewable energy is more widespread, many suspect that hydrogen will be manufactured out of a clean, though not ideal, alternative fuel, natural gas.
<font size="2" face="Verdana, Helvetica, sans-serif">Aargh! Why is it that the media still believes Pimentel's study, and it's the only one they ever cite. His study has been shown to be a steaming load of horse plop over and over again. Studies by the DOE, EPA, USDA, and Argonne National Labs have all shown that ethanol has a net positive energy balance, as well as many univiersity studies. Pimentel's is the only study to ever claim it has a negative energy balance - and his study revolved almost entirely around ridiculous assumptions and outdated technology (old farming techniques and ethanol plants). It's amazing that there are several more thorough studies done by both independent universities as well as governmental organizations that have found that ethanol has a net positive energy balance, yet Pimentel's lone study using outdated data (i.e. farming technology from the 70s, even though from '78-'94 farmers increased production per acre by 80% while keeping energy use constant) claimed it had a net negative energy balance - and Pimentel's is the study always cited by the media. It's almost enough to make you believe in DTY's conspiracy theories.But ethanol's green image has faded of late. Diesel tractors plant, fertilize, and harvest the corn used to make ethanol, and substantial coal-fired electricity is used to process the grain. Cornell University scientist David Pimentel, author of a study showing ethanol consumes more energy than it produces, calls it "unsustainable, subsidized food burning."
<font size="2" face="Verdana, Helvetica, sans-serif">The Sierra Club is run by perhaps the dumbest people of any environmental organization (except perhaps Greenpeace). Absolute morons. On the NOx issue - there are many catalytic converters available now that almost entirely eliminate NOx emissions (on the order of 99%) - but, they get killed by sulfur. So, they can't be installed on new diesel vehicles, since manufacturers have to assume that they'll be run on the typical high sulfur petro diesel in this country. Running on biodiesel though (or even ULSD), they can easily be used, and eliminate practically all NOx emissions. If the heads of the Sierra Club didn't have their heads so far up each other's rear end, they'd realize that natural gas is still a fossil fuel, and still has far far far more net CO2 emissions than biodiesel - even biodiesel made with natural gas derived methanol.Biodiesel also increases emissions of one smog-producing pollutant, nitrogen oxide, or NOx. Although technical solutions, such as adjusting engine timing, appear to be available, some environmentalists remain lukewarm. Daniel Becker, head of the Sierra Club (news - web sites)'s energy program, says the "french fry grease hustlers" are not competing with petroleum at all but are vying for market share against an alternative fuel his organization prefers: natural gas.

ADM stock has been pretty stagnant, the dividend is not too bad though.
For the company that supplies almost all the soy-based Biodiesel in North America and 2/3s of the RME to the European biodiesel fuel market, you'd think they be doing better than they are.
Here is the largest Biodiesel producer in North America and Europe and they don't look very good.Neither does Cargill, their main competitor for the biodiesel market.
The marketing hype that they put out do does seem to catch a few though.
<font size="2" face="Verdana, Helvetica, sans-serif">The people that supply 2/3s of the total biodiesel used in North America and Europe are in fact:Originally posted by SkyPup:
The Big Bean has been spreading nitrogen-phosphorous fertilizers all over the country polluting the land and the water.
The Big Bean has been spreading pesticides, herbicides, fungicides, all over the country polluting the land and the water.
The Big Bean has been one of the most highly criticized corporations for it abuse of power fair employment and substandard menial wages.
The Big Bean supplies greater than 2/3 of all soy derived Biodiesel in North America and greater than 2/3 of rapeseed derived Biodiesel in Europe.
The Big Bean has released genetically modified germ seed into the environment.
It's is no different than Big Oil, except the BD-100 users think that somehow they are "Green"
But in reality, they are not!
