1. Lecture 5: Review Questions and Fossil Fuels Issues

2. What are the three major forms of fossil fuels?

3. nonrenewable natural resources!

4. What is a hydrocarbon?

5. Small, light molecule-> gas
Larger, heavier molecule -> still a gas

6. Propane tanks

7. butane

9. Coal- huge, complex hydrocarbons!

10. The energy found in fossil fuels is a form of:
a. Nuclear energy
b. Potential energy
c. Chemical energy
d. Kinetic energy
e. Sunlight energy

11. -energy of position-

12. If the value of crude oil increases from ~$100 a barrel to ~$200 a barrel (42 gallons in a barrel):
A. The proven reserves of Saudi Arabia will increase B. Primary extraction will decrease C. Secondary extraction of oil will increase D. technically recoverable reserves will increase E. economically recoverable reserves will increase

13. How much oil is there in the world?

16. How much oil is used on a daily basis?

18. How many more years will oil the supply last?

19. What assumptions did we make in performing this calculation?

20. How much oil is there in the world?

21. "Since oil became a major energy source about 100 years ago, about 539 billion barrels of oil have been produced outside of the U.S. We now estimate the total amount of future technically recoverable oil, outside the U.S., to be about 2120 billion barrels."

22. “The USGS estimates that the mean undiscovered, conventional reserve additions in the world total 665 billion barrels of oil (bbo).”

24. What is peak oil?

25. Peak Oil and the US http://www.eia.gov/countries/data.cfm#undefined

26. Recent US oil production data

27. Global Peak Oil

28. A glimpse of the future?

31. How do we access crude oil, natural gas, and coal?

32. Crude oil and natural gas:

35. North Williston, Dakota
North Williston, Dakota

41. Subsidence is potentially dangerous, and can cause environmental problems like altered terrain and hydrology

42. Surface strip mining for coal became more developed and used in the 1930s and on.

43. Mountaintop removal- extreme strip mining

44. Mine Reclamation

47. Waste water?

48. What do we have to do to FFs before we use them?

49. VICKSBURG, MISS.Cleanup crews with booms skimmed oily water from the Mississippi River a day after a barge with more than 80,000 gallons of oil struck a railroad bridge near Vicksburg, spreading a sheen of light crude that kept part of the waterway shut to ship traffic Monday, authorities said.

53. Natural Gas
Christmas Tree

56. How we use fossil fuels?
