Presentation Transcript

  1. Fossil Fuels ch. 19 • Oil, Coal, Natural gas • How long are each expected to last • Location of major reservoirs • Major pros and cons of each type • What are the major environmental advantages and/or hazards? • What are the major human health issues?

  2. Carbon dioxide emissions per unit of energy produced

  3. Fossil Fuels: Hydrocarbons • Coal: black solid, carbon rings • Oil: liquid, long hydrocarbon chains • Natural Gas: 1C to 3C so light, it’s a gas!

  4. Coal

  5. Sample structure of coal

  7. Coal as energy source

  8. Oil

  9. Finding Oil: Seismic Surveying

  10. Extraction of Oil

  11. Proportions after refining

  12. Inflation adjusted price of oil

  13. Conventional Oil as energy source

  14. Non-conventional Oil • (not in a liquid form that can be drilled and pumped) • Oil Shale: US has largest supply • Tar Sands: Canada has largest supply

  15. Oil Shale

  16. http://www.youtube.com/watch?v=Qz148W0Gxe4 National Oil Shale Association video on methods of extraction and amounts in US (start at 4 min) 75% of world’s oil shale in US ½ of that in Green River Formation (2 ½ trillion barrels, over double the oil in Saudi Arabia). Majority of US oil shale is on federal lands, requires federal agreement to develop. In situ and ex situ extraction.

  17. Before and after tar sands mining in Alberta, Canada

  18. Keystone XL Pipeline from Alberta’s Tar Sands to Houston Texas

  19. http://www.youtube.com/watch?v=YkwoRivP17A Canadian tar sands as the largest industrial project on the face of the earth, affecting land area the size of Florida and England.
