Presentation Transcript

  1. NON-RENEWABLE ENERGY Coal Oil Natural gas nuclear

  2. definition • Non-renewable-  any natural resource that  cannotbe replenished by natural means at the  same rates that it is consumed Examples?

  3. COAL • How mined? • Surface • Underground • Longwall

  4. COAL • Processing steps • Washed • crushed

  5. COAL • uses

  6. DTE Monroe Coal plant

  7. How it works

  8. coal advantages disadvantages Produces CO2 when burned Produces ash- must be disposed of • Plentiful in US • inexpensive

  9. OIL • How mined? • Drilled • Pumped out • Into pipeline

  10. OIL Processing (refining) steps: Boiled Separates based on boiling point and density

  11. Oil uses

  12. Oil Advantages disadvantages Emits CO2 rely on foreign sources Oil spills • High heating value • Abundant • Easy to refine

  13. NATURAL GAS • How mined? • Fracking • Force chemical laden water thru fractures and breaks up shale • Releases oil and gas

  14. Processing (refining) • Removes impurities • Mainly sulfur

  15. Natural Gas advantages diadvantages Hard to recover from ground Contaminate groundwater? • Burns cleaner • Inexpensive • No ash • High heating value

  16. NUCLEAR • Uranium mining • Surface mining (mostly)

  17. Uranium processing • Crush • Purified • Dried • Yellow cake • Enriched to concentrate

  18. Uranium uses? • Nuclear power plants (electricity) • Nuclear weapons

  19. Nuclear power planthow it works

  20. Fermi 2, Monroe Michigan

  21. nuclear • Advantages • No emissions • Cost efficient • Disadvantages • Radioactivity • Nuclear waste • Plants expensive to build
