The researchers examined three ways of using sunlight to power cars: a) the traditional method of converting corn or other plants to ethanol; b) converting energy crops into electricity for BEVs rather than producing ethanol; and C) using PVs to convert sunlight directly into electricity for BEVs.

Making ethanol from corn reduces atmospheric releases of the greenhouse gas carbon dioxide because the CO2 emitted when the ethanol burns is «canceled out» by the carbon dioxide taken in by the next crop of growing plants, which use it in photosynthesis.

For the last wave of new ethanol plants, the Energy Return On Input (EROI) for corn ethanol is 1.5 to 1.8 and higher.

To produce enough corn - based ethanol to meet current U.S. demand for automotive gasoline, we would need to nearly double the amount of land used for harvested crops, plant all of it in corn, year after year, and not eat any of it.»

Trees may not take as much CO2 out of the air as corn plants do but they only have to take out less than half as much, since three to four times as much CO2 is in the whole corn plant as there is in the ethanol produced from it.

One hundred percent of the CO2 from burning ethanol in automobiles comes from the corn plant and was taken from the air.

For example, with such genetically - engineered biocatalysts it is not only grains of corn but corn cobs and most of the rest of the corn plant that may be used to make ethanol.

Ethanol more energy - efficient than oil, finds study: Using ethanol — alcohol produced from corn or other plants — instead of gasoline is more energy - efficient that oil say researchers at the University of California, BeEthanol more energy - efficient than oil, finds study: Using ethanol — alcohol produced from corn or other plants — instead of gasoline is more energy - efficient that oil say researchers at the University of California, Beethanol — alcohol produced from corn or other plants — instead of gasoline is more energy - efficient that oil say researchers at the University of California, Berkeley.

Dr. Daniel Nepstad of the Woods Hole Research Center said the growing demand for corn ethanol means that more corn and less soy is being planted in the United States.

And finally on the renewable fuels side, it includes a $ 20 million program to build a cellulosic ethanol facility to create the first pilot - plant (we hope) that will produce ethanol from woody biomass as opposed to corn, and thereby drastically raising the energy balance of the ethanol.

In 2007 26 % of the US corn production has diverted to create biofuel with a 7 % net increase in carbon dioxide emitted if one includes the energy cost for fertilizer, to harvest the corn, to haul the corn to the biofuel plants, and to triple distil the ethanol.

Based on the cost for plants like the one BP proposed in Florida, the cost could be 10 times higher for a cellulosic plant than a corn ethanol one, at least for the first plants, says Wallace Tyner, a professor of agricultural economics at Purdue University.

Bioethenol — Bioethenol is ethanol derived from the fermentation of plant matter (such as corn, switchgrass, grains or sugarcane).

At issue is whether to suspend a five - year - old federal mandate requiring more ethanol in gasoline each year, a policy that has diverted almost half of the domestic corn supply from animal feedlots to ethanol refineries, driven up corn prices and plantings and created a desperate competition for corn as drought grips the nation's farm belt.

As corn prices have risen, refineries have scaled back production, idled dozens of plants and sold ethanol inventories.

As I've said before and will continue to say until we stop opening corn ethanol plants, corn ethanol is a dead end and of limited utility as even an intermediary step towards better biofuels.

Another critic argues that the studies fail to consider no - till cultivation of biofuel crops, which actually increase soil carbon storage, and that corn ethanol plants are converting to renewable energy, thus decreasing their emissions - meanwhile they are competing against fossil fuels like oil from tar sands that have an increased carbon footprint even compared to conventional gasoline.

Since cellulosic ethanol is created by using all of the parts of the plant being used (instead of the 10 %, mainly the edible part, of the plant), in all likelihood, if this process turns out to work as advertised, we could use the discarded parts of corn, or non-edible plants such as switchgrass, so food production would not have to be drastically increased.
