Transcript

  • 1. Petroleum Unit Part D
  • 2. Energy throughout History
    • Biomass- burning wood
    • Coal- mined and burned
    • Petroleum- drilled for crude oil
    • Natural gases- drilled from reservoirs
    • Nuclear fission-harvested out of radioactive material
  • 3. Alternative sources of fuel
    • Biodesiel
    • Ethanol
    • Natural gas
    • Solar power
    • Wind power
    • Hydrogen
    • Hydroelectric power
    • Liquid coal or coal water
    • Fossil fuels
  • 4. Alternative sources of fuel
    • Hybrid vehicles
    • Electric power: more than one half of the U.S.’s power comes from coal.
    • Electric cars
  • 5. Better than Petroleum
    • Plants or animal fat  biodiesel
    • Produces less air pollutants
    • 78% less carbon dioxide emissions
    • Nontoxic Diesel
  • 6. Better than Petroleum
    • Start with more end with less
    • Takes lots of energy for large quantities
    • Takes longer to burn
  • 7. Alternative fuel Vehicles
    • Ethanol
      • Alcohol-based fuel
      • Also called E10 or gasohol
      • cheaper in some areas, more expensive in others
      • 2,000 stations sell E85
      • 20-30% drop in mpg  ethanol’s lower energy content
    • Biodiesel 
      • can be used pure (B100) or blended with petroleum diesel.
  • 8. Alternative fuel Vehicles
    • Natural Gas
      • Fossil fuel, mostly methane
      • Dedicated run only on natural gas
      • dual-fuel or bi-fuel
    • Propane
      • Liquefied petroleum gas (LPG)
      • Last model created in 2004
  • 9. Alternative fuel Vehicles
    • Hydrogen 
      • Used in fuel cells power electric motors or burned in internal combustion engines (ICEs).
      • Produced domestically from several sources
      • No air pollutants or greenhouse gases
    • Hybrid Gasoline-Electric Power 
      • Not on market
      • Has 40% fuel efficiency
