Ethanol vs. Gasoline

By: Erica Tucker

intro to the fuels
Intro to the fuels
  • Gasoline:
    • Produced from petroleum
    • Non-renewable
    • Types:
      • Pure gasoline
      • Gasohol (combination of gasoline and ethanol)
intro to the fuels cont
Intro to the fuels (cont.)
  • Ethanol:
    • Derived from plants
    • Renewable
    • Types:
      • Corn-based
      • Sugarcane
      • Cellulosic (made from the sugar substrate of plants)
  • After each side of the argument is presented, my thesis is:
    • The BEST combination of each fuel needs to be used to improve environment and maintain necessary resources.
main points
Main points
  • Benefits and downfalls to both gasoline and ethanol
  • The new forms of ethanol being researched
  • What these new forms bring to the table for the U.S.
  • The need for alternative fuels
  • New technology
benefits of gasoline
Benefits of gasoline
  • Cheaper than ethanol in the long run
  • Engine burns it more efficiently
downfalls to gasoline
Downfalls to gasoline
  • Worse for environment
    • Releases more Hydrocarbons and Carbon Dioxide
  • Non-renewable
    • This issue leads to a need of alternative fuels
benefits of ethanol
Benefits of ethanol
  • Cheaper to produce
    • Made from corn- renewable resource
  • Better for the environment
    • Emissions released are less harmful
downfalls to ethanol
Downfalls to ethanol
  • Using corn to produce ethanol would decrease amount used for feeding the people of the world
    • World doesn’t produce enough corn as it is
  • May be more expensive in the long-run than gasoline
    • Less-efficient burning in engine
new forms of ethanol
New forms of ethanol
  • Sugarcane Ethanol:
    • Made from sugarcane
      • Renewable
    • More needs to be produced, this space is available
    • Benefits:
      • Reduction of carbon emissions by 66 million tonnes
        • “tonne” here means 1000 kilograms
what this means for u s
What this means for u.s.
  • U.S. was tenth in sugarcane production as of 2005
    • Need to either produce or import more sugarcane
  • Car manufacturers need to produce engine to run efficiently on sugarcane
  • Although promising, has downfalls
    • Also uses valuable food sources that could be feeding the starving people of the world
new forms of ethanol cont
New forms of ethanol (cont.)
  • Cellulosic Ethanol
    • Produced by breaking down sugar substrate of plant material
  • Cellulose makes up between 75 and 85 percent of plant material
    • If broken down too, corn could be used more efficiently and less would be needed to produce the same amount of fuel
  • 90% gasoline and 10% corn-based ethanol
    • Same price at pump, but emissions are not as harmful
  • Downfall
    • “Expensive and energy intensive to produce” (Columbia)
need for alternative fuels
Need for alternative fuels
  • Nations need to keep up with demand of food sources for ethanol, but also maintain adequate production of crops for feeding the world
  • Need for fuel that is safe for the environment and also competitive with gasoline’s efficiency in engines
additional goal reduce overall use of energy sources
Additional goal: reduce overall use of energy sources
  • New technology has surfaced
    • Electric cars
      • Run on electricity and gasoline
      • More beneficial to environment because they release less harmful emissions than a car that runs only on gasoline
      • Chevy Cruze Eco
        • Better gas mileage
making progress
Making progress
  • Benefits of Electric Cars:
    • Require less fuel therefore reducing needed amount of depleting petroleum
  • If progress continues
    • Electric-ethanol cars?
    • 100% electric cars?
      • Resolve problem of overuse of petroleum and remove harmful emissions
in conclusion
in conclusion…
  • Despite positives of gasoline, long-term survival of society requires use of alternative fuels.
  • Due to drawbacks, society is not yet ready to completely replace gasoline because of greedy consumption of petroleum
  • Many hurdles to conquer and further research and analysis is necessary for reduction of petroleum-based products and increase in alternative fuels
