ethanol production does not reduce atmospheric CO2.
By comparison The US oil consumption increased by 137.6 million barrels from 6851.4 mmbbls in 2009 to 6989.0 mmbbls in 2010 so
this ethanol production did not stop the increase in US oil consumption and only served to raise the price of corn through government subsidies affecting only the poor.
Not exact matches
The explanation for the hefty price of free - range eggs has something to
do with the dynamics of increased corn
production for
ethanol and the resulting decrease in
production of other less expensive feed.
(Worse, use of
ethanol instead of gasoline
does little to reduce net carbon emissions once the energy - intensive full cycle of
ethanol production — including the energy - intensive fertilizer and transport needs — is taken into account.)
The cellulosic
ethanol process we developed was unique because it
did not require multiple processing steps and the use of expensive laboratory - modified enzymes, the
ethanol bioprocessing system uses significantly less water and energy in
ethanol production resulting in larger yields per ton of biomass.
Corn - based
ethanol doesn't meet that test and won't benefit from the new standard, CARB says, because diverting corn into
ethanol production increases deforestation and the clearing of grasslands.
Part of the $ 150 billion, 10 - year expenditure — the centerpiece of his energy plan — is to develop these resources as well as shift
ethanol production from corn to cellulose - based sources that
do not affect the food supply.
Farmers make the fuel by chemically treating corn kernels to isolate the sugars and then feeding the sugars to yeast, which digests them and secretes
ethanol.Not only
do the corn husks and stalks go to waste, but
ethanol production has driven up the price of the corn that is used for food by reducing its availability.
I don't see how our subsidies for making
ethanol from corn, for example, spill over to the
production of high fructose corn syrup.

do now with «threatened tropical rain forests» is to harvest all their timber, then clear the land, then grow organic sugarcane for
ethanol production.»
Whatever you grow that you don't use for food can then be fed into biofuel
production (as well as biochar
production, as a soil amendment, meaning NEGATIVE emissions), and then you have some amount of
ethanol, biodiesel, or bio-based hydrocarbon product.
I believe the best thing to
do now with «threatened tropical rain forests» is to harvest all their timber, then clear the land, then grow organic sugarcane for
ethanol production.
Bob Dinneen, president and CEO of the Renewable Fuels Association says don't blame American
ethanol production.»
Robert Rapier, writing about this issue in January, had called commercial cellulosic
ethanol production a «unicorn» because it was something that doesn't exist, no matter how much we want it to.
The Midwest
does not have the highest solar potential in the country (that is found in the Southwest), but its potential is nonetheless vast, with some parts of the Midwest having as good a solar resource as Florida.75 More than one - quarter of national installed wind energy capacity, one - third of biodiesel capacity, and more than two - thirds of
ethanol production are located in the Midwest (see also Ch.
And it Doesn't include the
production of algae and duckweed, which is currently at 6,000 gallons per acre per year, for oil and
ethanol respectively, plus co-product biomass that can go to feed or fuel depending on demand.
It
does not release carbon that would otherwise stay stored underground, as occurs with fossil fuel use, but when starch, such as corn, is used for
ethanol production much energy, including fossil - fuel energy, is consumed in the process of fertilizing, plowing, and harvesting.
Aurora is one of dozens of start - ups vying to bring an algae - based product to market that will be competitive with petroleum but
does not take farmland out of food
production, an issue that has plagued the corn
ethanol industry.
Bloomberg Businessweek explains more clearly than EPA
does why the agency had to back - peddle so furiously: «The Environmental Protection Agency proposed requiring less cellulosic
ethanol to be blended into gasoline next year than sought under U.S. law because
production of the alternative fuel hasn't reached commercial scale.»
They say the technological fixes also distract from more challenging social reforms like slowing the rate of population growth, shifting away from crops like corn
ethanol that don't put food on the table, or ending subsidies for livestock
production, which currently eats up an appalling 75 percent of the world's agricultural land.
When demand for corn
ethanol rose, so
did corn prices, as
did the acres diverted to corn
production.
An
ethanol mandate that causes little economic harm when unemployment rates are low, corn
production is high, and China's demand for U.S. corn imports is low could inflict severe harm when the opposite conditions obtain — as they
do today.
Finally,
ethanol production and the RFS don't even reduce greenhouse gas emissions.
There are more emissions from the total Corn
Ethanol production sequence and use as an alternative and additive to fossil fuels than if ordinary fossil originated fuels were just used to
do the job.
Researchers Tim Searchinger and Ralph Heimlich make the case that policies that lead to setting aside land for biofuels
production — like our own
ethanol policies in the United States — ultimately
do little to curb greenhouse gas emissions.
Cardayre argues that LS9's biofuels offer several benefits that make them more attractive as an alternative to fossil fuels than
do ethanol - derived fuels, including higher cost - efficiency and lower energy consumption in
production (65 % less energy).
Does it matter whether there is a net energy loss in the
production of corn - based
ethanol --- that is, it takes more fossil fuel energy to produce
ethanol than the
ethanol itself produces?
Wind energy holds great promise for the state, as
do other renewables such as bioenergy,
ethanol production, and even solar energy.
