Petroleum Unit

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