1. Chapter
Nonrenewable Energy

2. Fossil Fuels Fossil fuels – remains of ancient organisms Changed into:
Oil
Coal
Natural gas

3. Fossil Fuels
Problems:
Supply is limited
Causes environmental problems

4. Uses Cooking Transportation Manufacturing Heating and cooling
Natural Gas
Transportation
Petroleum
Manufacturing
Coal
Heating and cooling
Generating electricity

5. Electricity Fossil fuels  electricity More convenient
Travel long distances quickly

6. Disadvantages
Difficult to store
Other energy sources generate it

7. Electricity
Electric generator – machine that converts mechanical energy into electrical energy
Mechanical energy – energy of motion

8. Turbine
Turbine – wheel that changes moving liquid energy into electrical energy

13. Power Plant 1. Boil water 2. Stream 3. Turns turbine
Coal or gas heated
2. Stream
3. Turns turbine

15. Energy Use

16. Energy in the U.S.
Uses more energy per person than any other country except Canada and United Arab Emirates

17. Energy in the U.S. 25% of energy used in transportation
Other countries – rails systems
Smaller size

18. Energy
U.S. and Canada – some of the lowest gas taxes in world

19. Fuel Deposits
Why is there oil in Alaska and Texas but not in Florida?

20. Coal Remains of plants in swamps Hundreds of millions of years ago
300 – 320 million years

22. Coal Inexpensive Little refining
½ of electricity in U.S. comes from coal

23. Coal Mining
Environmentally damaging
Dangerous for humans

25. Coal Bituminous – high heat, less pollution Lignite – low quality
Sulfur released after burning
Acid rain

27. Petroleum Oil that is pumped from the ground
Crude oil
Petroleum product – anything made from crude oil
Plastics
Chemicals

28. Oil and Natural Gas Decay of tiny marine organisms Ocean bottom
Compressed into carbon-based molecules
Trapped in porous rocks

30. Oil Deposits Most are found in the Middle East Also: U.S. Venezuela
North Sea
Siberia
Nigeria

31. Oil Spills
Double hulled tankers
Quick response time

33. Oil Spill – Deep Horizon
April 20, 2010
Worse since Exxon Valdez in Alaska during 1980’s
200,000 gallons
11 workers dead

35. Recent oil spill

36. Natural Gas In the past it was burned off Technology Clean burning
Though of as a nuisance
Technology
Transport gas
Clean burning

37. Oil Reserves
Oil reserves – oil deposits that can be extracted at a profit
Running out
Oceans
