Sentences with phrase «ethanol from corn reduces»

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.

Not exact matches

Cellulosic biofuel could reduce our reliance on foreign petroleum without the problems associated with ethanol from corn — if we can figure out how to extract its energy economically

The key factors determining carbon emissions for corn - based ethanol are (1) whether coal or natural gas is used to power the ethanol plant, (2) whether distillers grains are dried or sold wet, and (3) whether expansion of corn acreage comes mainly from reduced acreage of lower - value crops or if idled land is brought into production.

Let's reword all this and say that we want to improve energy efficiency and reduce waste and real pollution wherever we can, we want to move away from ever scarcer and costlier fossil fuels, particularly those that have to be imported from a price - fixing cartel of nations that are generally hostile to us and we want to develop new domestic sources of energy, be that shale oil and gas, new biofuels (not silly corn - to - ethanol schemes) and other renewable energy sources, etc..

From 2007 to 2013, corn ethanol interests spent $ 158 million lobbying for more mandates and subsidies — and $ 6 million in campaign contributions — for a fuel that reduces mileage, damages engines, requires enormous amounts of land, water and fertilizer, and from stalk to tailpipe emits more carbon dioxide than gasolFrom 2007 to 2013, corn ethanol interests spent $ 158 million lobbying for more mandates and subsidies — and $ 6 million in campaign contributions — for a fuel that reduces mileage, damages engines, requires enormous amounts of land, water and fertilizer, and from stalk to tailpipe emits more carbon dioxide than gasolfrom stalk to tailpipe emits more carbon dioxide than gasoline.

It's now well - established that large - scale U.S. production of biofuels such as ethanol from corn has accomplished little or nothing (or even negative) in its stated goals of reducing oil dependence and cutting emissions of greenhouse gases, and has functioned instead as a full - employment program for agribusiness (and a political production racket for Iowa and other corn - growing states).

The initiative aims to reduce dependence on foreign oil and cut emissions from transportation, but some analysts have questioned the effectiveness of the program, since the bulk of «renewable» fuel is expected to come from corn ethanol, which environmentalists say has mixed climate benefits.

Far from having a substantial impact on reducing net emissions of GHG, Wolf says, European rapeseed oil - based diesel and U.S. corn - based ethanol have in fact only made small contributions - 13 % less than conventional diesel and 18 % less than petrol, respectively.

Many people believe that using ethanol from corn would greatly reduce the emission of gasses implicated in global warming.

(Note that the study did not look at first generation biofuels made from tropical crops like sugarcane or sweet sorghum which reduce emissions far more than corn ethanol; for sugarcane ethanol, the reduction is as large as that of cellulosic biofuels, earlier post.)

Aimed at reducing U.S. reliance on foreign oil, the Renewable Fuels Standard, or RFS, would require 13.2 billion gallons of ethanol to be made from corn this year.
