Objectives Describe how ethanol may help improve
public health Describe the benefits of ethanol to the
environment Explain how ethanol may help stimulate
the economy Describe what energy security is and
how using ethanol can help attain it Explain the future of ethanol Explain the suggested actions to support
ethanol
3
Domestically produced and renewable
Nontoxic, biodegradable, sulfur-free
May produce cleaner tailpipe emissions
Why Consider Ethanol?

4
Advantages of Ethanol Energy self-sufficiency Creation of jobs within the U.S. Promotes U.S. agricultural sector Reduced emissions

6
There are many benefits of using ethanol to fuel vehicles: Betterment of health and
environment Benefits to the U.S. economy National energy security Reduce dependence on foreign oil
Ethanol Benefits
7
Carbon monoxide emissions are responsible for up to 20% of smog formation
Smog can negatively affect the respiratory systems of those with preexisting conditions, the young, and elderly
Ethanol/ethanol blends burn more completely, produce fewer carbon monoxide emissions
Health Benefits
8
Ethanol is highly biodegradable Ethanol used as vehicle fuel reduces
harmful emissions Plants used to create
ethanol absorb carbon dioxide during growth
Ethanol does not contain sulfur
Environmental Benefits

9
Creation of domestic jobs Growth within U.S. agricultural
sector In 2011, ethanol industry added
more than $42 billion to U.S. GDP, supported more than 400,000 jobs
Economic Benefits
10
U.S. = one of the greatest exporters of agricultural products
About half of U.S. oil used in 2010 was imported
Ethanol can be produced from domestic resources
Domestic production lessens dependence on foreign oil
Energy Security Benefits
11
Ethanol’s energy balance Ethanol can be produced from
renewable biomass resources Biomass resources can be grown
within the U.S.
Renewable Benefits
12
Energy Policy Act (EPAct) of 2005 Renewable Fuels Standard (RFS) 9 billion gallons in 2008 – 36
billion gallons by 2022 Nearly all gasoline sold in the U.S.
contains ethanol
Ethanol – Today and Tomorrow
13
The Future of Ethanol Nearly all gasoline in the U.S.
contains some ethanol RFSs set requirements for minimum
amount of ethanol use Several manufacturers produce
vehicles that are considered flexible fuel (capable of running on E85)
As production increases, the price of ethanol may decrease
14
Suggested Actions Increased ethanol
production = lessened dependence on foreign oil
Manufacturers continue to introduce more FFVs
Plans to produce different FFVs seem a viable option

Educate consumers about the benefits of ethanol
Price point usually below conventional gasoline prices
Increasing number of E85 stations across the U.S.

Special Note:The Energy Independence and Security Act of 2007 (EISA) requires use of 36 billion gallons of renewable transportation fuels in the U.S. by 2022. Of that quantity, 16 billion gallons must be cellulosic biofuels. Ethanol from corn is capped at 15 billion gallons.

Upon completing this section, can you: Describe how ethanol may help improve
public health? Explain how ethanol may help stimulate
the economy? Describe the benefits to the environment? Explain the future of ethanol? Describe what energy security is and how
using ethanol can help attain it? Explain the suggested actions to support
ethanol?

1. List four characteristics of ethanol as a fuel.
2. True or False: Ethanol made from corn today results in a GHG emission reduction of 10% compared to conventional gasoline.
3. True or False: Ethanol production has a positive energy balance.
4. True or False: Nearly all gasoline used in the U.S. contains some ethanol.
