  1. Non-Renewable Energy Resources

  2. Global Energy Consumption by Source • What is the total percentage for fossil fuels? • 80% • What is the total percentage for nuclear?

  3. Fossil fuels • Oil (crude oil, petroleum) • Coal • Natural Gas •  all formed millions to hundreds of millions of years ago • Carboniferous age (360-280 million years ago) • ``cooking’’ of dead organic matter

  4. How do we generate electricity from these fuel sources? • -A fancy way of boiling water • Heat is generated by burning of fossil fuels or nuclear reaction • Heat causes water to boil which generates steam • Steam causes a turbine to spin which generates electricity

  5. Coal -World coal production in 2010 -http://www.eia.gov/todayinenergy/detail.cfm?id=4210

  6. Coal

  7. Coal • How does coal form? • Forms from dead and decaying organic material (plants) in swampy areas • As it gets buried, temperature and pressure “cook” it

  8. Coal

  9. Coal • Shaft mining • Less environmental impact than open pit • More dangerous

  10. Coal • Open pit coal mine • Very large! Some can be seen from space

  11. Coal More impacts on the environment Less dangerous than shaft mining

  12. Coal • Burning coal produces air pollution • All coal burning produces sulfur which can cause acid rain • In China there are “blue sky” ratings based on the days Air Quality Index (AQI) as a result of air pollution

  13. Natural Gas • Mainly methane: CH4 • Does methane smell? • No. The gas that is piped into your home for heating or cooking has a smell added to it so you can detect a leak or malfunctioning appliance. • Burns relatively cleanly

  14. Natural Gas • Electric power is the largest use of natural gas • Residential use includes home heating and cooking

  15. State-of-the-art landfill Captures methane

  16. In seas Small organisms—plants and animals—settled out in the mud at the bottom Buried under more silt, mud Cooked under heat and pressure Oil eventually moved into permeable rock—reservoirs—where oil is found today Tiny plants and animals Natural Gas and OilFormation

  17. Natural Gas and Oil

  18. Oil Top 10 oil producing countries for 2007 in millions of barrels per day (mbpd)

  19. Oil (tar sands) Tar Sands in Alberta, Canada

  20. Oil (tar sands)

  21. Oil

  22. Oil (tar sands)

  23. Oil (tar sands)

  24. Prudhoe Bay Field Trans-Alaska Pipeline 1300 km (800 mi) long Port of Valdez http://en.wikipedia.org/wiki/Trans_alaska_pipeline

  25. Trans-Alaska Pipeline http://en.wikipedia.org/wiki/Trans_alaska_pipeline

  26. Exxon Valdez aground on a reef, Prince William Sound, Alaska -March 1989 11 million gallons of oil were spilled (roughly equal to 17 Olympic size swimming pools) http://response.restoration.noaa.gov

  27. Oil • Deep ocean oil drilling is more difficult and more expensive than drilling on land

  28. The Deepwater Horizon offshore oil platform caught fire and sank with the loss of 11 crew members, as the well was being closed pending later production. April 20, 2010

  29. Oil

  30. Peak Oil Peak Oil- the point in time when a maximum rate of oil extraction is reached

  31. Peak Oil
