  1. Ethanol vs. Gasoline By: Erica Tucker

  2. Intro to the fuels • Gasoline: • Produced from petroleum • Non-renewable • Types: • Pure gasoline • Gasohol (combination of gasoline and ethanol)

  3. Intro to the fuels (cont.) • Ethanol: • Derived from plants • Renewable • Types: • Corn-based • Sugarcane • Cellulosic (made from the sugar substrate of plants)

  4. thesis • 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.

  5. 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

  6. Benefits of gasoline • Cheaper than ethanol in the long run • Engine burns it more efficiently

  7. Downfalls to gasoline • Worse for environment • Releases more Hydrocarbons and Carbon Dioxide • Non-renewable • This issue leads to a need of alternative fuels

  8. Benefits of ethanol • Cheaper to produce • Made from corn- renewable resource • Better for the environment • Emissions released are less harmful

  9. 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

  10. 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

  11. 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

  12. 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

  13. gasohol • 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)

  14. 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

  15. 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

  16. 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

  17. 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
