ETHANOL FUEL
Source: (C6H12O6)
Corn
Sugarcane
Switchgrass
What is ethanol?
what are the global energy problems
that we are facing ?
Depletion of fossil fuel

Environmental pollution caused by the fuel combustion
Alternative?
SUPPORT ETHANOL FUEL!!
However... Is it perfect ?
LITERATURE REVIEW
Oppose:
More input

energy than

output.
Cause air contamination.
Cause food crisis.
Support:
Boost industrial development: benefit from the ethanol production.
Environmental friendly: less carbon
monoxide emssion.
Intrinsic predominance: low ignition point, common sources, useful secondary products.
It will become a popular and
widely used new energy
Most pople think:
Bias
People the
negative impacts of
ethanol fuel
ignore
most people have a bias believe without evidence that ethanol is a renewable and environmental-friendly source of energy
most people have a bias believe without evidence that ethanol is a renewable and environmental-friendly source of energy
Most people have a believe
without evidence that ethanol is a
renewable and environmentally-friendly
source of energy
Deep Understanding
1.Demand for significant investments in mant aspects
2.Fermentation is both the most important link and a cost-intensive process in the production system
3.Money spent on controlling pollution
Cost More Than It Worth!
Result
Methodology


It was anticipated that ethanol is a viable alternative to gasoline.
However
aggravate global food crisis
emit air pollutants
affect global economy
It may.....
possibilities to solve the problems
alga
Our Stand:
To improve rather than to abandon
Some limitations:
Conclusion
Thank you!
Q&A
Mechanism:

C6H12O6 → 2 C2H5OH+ 2 CO2 
Hypothesis:

Although Ethanol fuel is one good alternative energy, it has some negative impacts.
