  1. Energy Resources

  2. Learning objectives • To learn how fossil fuels were formed and how they are obtained • To consider how long they may last.

  3. Carbon based energy forms • These have provided the majority of the worlds energy since the early industrial revolution. • They are:

  4. How Coal was formed • http://www.youtube.com/watch?v=MBeXRRTGjNE • http://www1.teachertube.com/viewVideo.php?video_id=40991

  5. Where is the coal? Coal resources are located by geologists. It is thought that most of the world’s resources have already been located, but the continent of Antarctica remains unexploited.

  6. How is coal mined? • Originally harvested by hand this picture from NE England (Billy Elliot territory) shows the practice still taking place in 1939.

  7. Early pit mines • A medieval bell • pit from Scotland • (originally started • in the 1200s)

  8. What you would see today in the hills near Manchester

  9. Mine Shafts (adits) • As this 16th century German drawing shows mines became more complex

  10. Today Modern Mechanised USA More typical and traditional Pakistan

  11. Open Cast coal mines • Much more high tech, much more impact on surface environment, much more economical.

  12. Do this activity – on blackboard

  13. How are crude oil/natural gas formed • http://www.planet-scicast.com/view_clip.cfm?cit_id=2869 • http://www.youtube.com/watch?v=gqryaKRSQjE • http://video.google.com/videoplay?docid=-7470023822861761791#

  14. How oil and gas are formed contd

  15. How and where we find oil

  16. Natural oil seepage (Azerbaijan)

  17. How oil is obtained On land At sea http://www.youtube.com/watch?v=NNvmK9mUjvI&feature=relatedhttp://www.youtube.com/watch?v=Hy6M0II_I1A http://www.youtube.com/watch?v=-pzFVSB3Cnc

  18. First oil well • Titusville, Pennsylvania, US 1859. Drake’s well today

  19. Natural gas • Gas rigs being built in Scotland

  20. World reserves and usage • Fossil fuels will remain the primary sources of energy, meeting more than 90% of the increase in demand.  Global oil demand will rise by about 1.7% per year, from 75mb/d in 2000 to 120mb/d in 2030.  • World reserves (recent estimate) 1077498 million barrels • = about 25 ½ years supply at predicted 2030 usage

  21. Where the oil is

  22. Known resources (mid 2000s)

  23. Other factors to consider • 1. More may be found (Antarctica!) • 2. Usage may grow more or less than predicted • 3. Value will increase making currently uneconomic reserves workable • 4. Cost may increase reducing consumption. • 5. Global warming may become catastrophic and fossil fuel use may have to stop.

  24. Gas reserves

  25. Los Heroes

  26. Homework Oil formation (in teams) • Draw a poster to show the process of oil formation and its extraction. • Include • 1. the stages of its production • 2. information explaining how the oil is formed • 3. Information showing time scale • 4. Include it against a background of world oil producing areas. • 5. Include images showing its extraction explaining what is being shown. (5 marks per section)
