SUMMARY: ETHANOL
1.)
What is it? Ethanol
is a alcohol based fuel made by fermenting and distilling crops,
trees, and grasses (fueleconomy.gov). There are two types of ethanol
fuel. One is E10 which is a ten percent ethanol ninety percent
gasoline mixture. The second is E85 eighty five percent ethanol and
fifteen percent gasoline.
2.)
Where does it come
from? Ethanol can be produced from plants, grasses, trees, and crops
such as corn, soybeans, and sugarcane.
3.)
Current use and
availability? Ethanol is used for alcohol and for fuel. It is
available across the United States but mostly in the Midwest where
most crops used to make ethanol are grown.
4.)
Sustainability?
Ethanol is sustainable. It’s a renewable resource that will cut down
greenhouse gases and oil dependency.
5.)
Advantages /
Disadvantages. The advantages of ethanol are that it is domestically
produced, lowers the use of imported oil, creates jobs, and no
special fuel equipment is needed, and it can be used in gasoline
cars. The disadvantages of it are that it can only be used in
certain cars, lower miles per gallon, more expensive to produce,
requires too much farmland, takes more energy to make than it can
produce. (environment.about.com)
6.)
Environmental
concerns and benefits? The benefits are that ethanol will reduce the
emissions of greenhouse gases and the dependency of imported oil.
The concerns are that there will not be enough farmland to create
the ethanol needed to substitute gasoline.
7.)
How is it created?
First biomass feedstock are grown, collected, and transported to an
ethanol production facility. Second the feedstock are made into
ethanol at a production facility then transported to a blender or
fuel supplier. Finally the ethanol is mixed with gas by the supplier
and then distributed. (afdc.energy.gov/fuels/ethanol.html)
8.)
Costs of use? The
price of ethanol goes with the price of crops. If corn is two
dollars a bushel than a gallon of ethanol will cost $1.00-1.20 to
make. The costs also include the natural gas or other heat sources
needed to heat it. The cost of ethanol varies from region to region
it may be cheaper in one part while more expensive in other parts.
