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
why consider ethanol
Why Consider Ethanol?
  • Domestically produced and renewable
  • Nontoxic, biodegradable, sulfur-free
  • May produce cleaner tailpipe emissions

Advantages of Ethanol

  • Energy self-sufficiency
  • Creation of jobs within the U.S.
  • Promotes U.S. agricultural sector
  • Reduced emissions
ethanol benefits
Ethanol Benefits
  • 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
health benefits
Health Benefits
  • 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
environmental benefits
Environmental Benefits
  • 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

economic benefits
Economic Benefits
  • 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
energy security benefits
Energy Security Benefits
  • 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
renewable benefits
Renewable Benefits
  • Ethanol’s energy balance
  • Ethanol can be produced from renewable biomass resources
  • Biomass resources can be grown within the U.S.
ethanol today and tomorrow
Ethanol – Today and Tomorrow
  • 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
slide13

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
slide14

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

slide15

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.
