Not at all. Ethanol is produced from field corn. Corn for human food is sweet corn. They are completely different, and neither has any effect on the other. Food costs are much more greatly affected by transportation costs than anything else.
As of 2011, approximately 45% of US corn production is being used for ethanol production.
Approximately 38% of corn produced in the US is used for ethanol production.
Ethanol production
Corn crops will likely continue to be used for ethanol production more than anything else. Of course, it will remain a food crop, too. Its price will vary widely in the coming years, though.
Assuming the dry-milling method of ethanol production (the most common), one 56-pound bushel of corn makes 2.7 gallons of fuel ethanol and 17.4 pounds of dried distillers' grain. This means that 69% of the corn went into the ethanol.
Usually it's called "field corn." It's a cultivar of corn grown predominantly for livestock feed, but also for ethanol production.
Currently a bushel of corn produces about 2.8 gallons of ethanol. With better varieties that figure will increase to 3 gallons. In the near future, the corn distillate will be processed again, yielding some more ethanol.
Yes, corn maize can be converted into ethanol through a process called fermentation. The starch in corn is first broken down into sugars, which are then fermented by yeast to produce ethanol and carbon dioxide. This renewable fuel is commonly used as an additive in gasoline to reduce emissions and enhance octane levels. Ethanol production from corn contributes to energy sustainability and supports the agricultural economy.
The key word in the answer is ETHANOL. Ethanol comes from corn. Therefore agriculture...grow corn, make fuel from the corn, power cars from Ethanol
Direct demand is the demand that the primary agent has for something. The primary agent desires the good or service for themselves. Indirect demand is the demand that arises for something by a secondary agent due to an interaction that occurs corresponding to the primary agent. For example: If a federal mandate occurs for ethanol to be blended at a level for the entire transportation fuel supply, the increase in corn demanded for producing ethanol is an indirect demand. The mandate may not be for corn use, but there is indirect demand for corn. However, consider that the ethanol production facilities that utilize corn for the production of ethanol have a direct demand for corn. The indirect demand for corn arises from the original demand for ethanol. The designation of direct or indirect is a matter of perspective for the question being asked.
In the US, ethanol is allowed to be blended into the gasoline supply as a part of the federal Renewable Fuels Standard (RFS) set by the US Environmental Protection Agency in an effort to help control petroleum-based pollution. Individual states' requirements for blending are intended to serve the same purpose. However, the nation's corn supply tends to be so large that these individual states laws have comparatively little effect on the market price of corn as a commodity, except when the price of crude oil and gasoline get low enough that it is not economically feasible to continue blending, or as a result of an extremely short production of corn. Commodity prices at the moment are only barely above the cost of production, and in fact the US is currently facing a considerable oversupply of corn.
Ethanol - the additive that goes into your gas tank is made--you guessed it--from corn. Demand for corn has skyrocketed, and so does the price for everything made from it, including Fritos corn chips.
