1 Energy Quiz Prep

2 What is a renewable fuel?

3 One that replaces itself quickly, such as firewood and water power

4 What is a non-renewabble fuel?

5 One that cannot be renewed or that takes millions of years to renew

6 What is an inexhaustible fuel?

7 A fuel that will replace itself as quickly as we can possibly use it

8 Crude Oil Is it renewable or non-renewable?

9 Non-renewable

10 Conventional nuclear fission
Is it renewable or non-renewable?

11 Non renewable unless we make plutonium in breeder reactors

12 Geothermal Energy Is it renewable or non-renewable?

13 Renewable

14 Solar Energy Is it renewable or non-renewable?

15 Inexhaustible, so it is renewable, at least for a few billion years

16 Wind Energy Is it renewable or non-renewable?

17 Renewable

18 Conventional Natural Gas
Is it renewable or non-renewable?

19 Non-renewable

20 Wind Energy Is it renewable or non-renewable?

21 Renewable

22 Coal Is it renewable or non-renewable?

23 Non Renewable

24 Biomass Is it renewable or non-renewable?

25 Renewable

26 Hydropower Is it renewable or non-renewable?

27 Renewable

28 What is the definition of a fossil fuel?

29 A fuel that was once living millions of years ago

30 What are the 3 fossil fuels?

31 Coal Oil Natural gas

32 How is coal extracted from the ground?

33 Either strip mining or underground mining

34 What is the environmental effect of mining coal?

35 It leaves mines or pits that fill up with acidic waste water that may have to be treated forever
It leaves huge piles of loose waste rock

36 Who uses the most coal?

37 Power plants

38 What are the environmental problems with burning coal?

39 Coal gives off more carbon dioxide than any other fossil fuel
Coal contains sulfur that when burned produces acid rain Some coal contains mercury and heavy metals.

40 How much coal supply do we have?

41 Hundreds of years

42 How are oil and gas extracted?

43 Deep wells are drilled

44 What is the environmental problem with drilling for oil and gas?

45 Oil Spills Uses a LOT of water Weak wells require HOT water Can cause land to subside

46 What is good about oil and natural gas?

47 They are convenient to store and ship
Oil is readily converted into gasoline Gasoline is portable for cars

48 What is the down side to using oil and N gas?

49 Carbon dioxide Acid Rain Smog We need it for other purposes. We have to import a lot of it

50 How much oil and N gas is available?

51 Only a few decades of proven reserves exist

52 Hydrogen Fuel Is it renewable or non-renewable?

53 Renewable from sea water

54 What is good about hydrogen?

55 It is portable, and it’s only emission is water

56 What is bad about Hydrogen?

57 It takes more energy in the form of electricity to make it than it gives off when you use it as a fuel

58 What is good about biomass?

59 The net amount of carbon dioxide produced is zero
The net amount of carbon dioxide produced is zero. Co2 is used by the plant, and when it is burned, the next crop uses it all up It can be made into portable car fuel

60 What is bad about biomass fuel?

61 It uses land that we need for food crops

62 What is good about hydropower?

63 It produces a lot of electricity without polluting the air or water

64 What is bad about hydropower?

65 Dams harm fish reproduction
Dam lakes fill up with silt Power has to be used near the dam

66 What is good about wind energy?

67 Totally non polluting

68 What is bad about wind power?

69 You never know when the wind will blow
The best winds are often not where there are people to use the power

70 How can we capture solar energy?

71 Photo cells Reflectors and boilers Passive heating

72 What is the problem with photocells?

73 They’re still pretty expensive
They don’t work when the sun isn’t shining

74 What is the problem with reflector boilers?

75 They take a LOT of room They don’t work when the sun isn’t shining

76 What is the problem with passive solar?

77 It is fairly limited to heating
They don’t work when the sun isn’t shining

78 What is good about home Geothermal Heat pump energy?

79 Low temp set with a heat pump are very efficient to run
Uses stored sun’s energy Save a LOT on heating and cooling Inexpensive to install

80 What is bad about geothermal?

81 Low temperature sets are only good for heating.
Hot sets can only be used in a few areas because the hot rock is too deep

82 What is good about Nuclear Fission

83 No air or water pollution
Relatively inexpensive to run once the plant is online Can build them close to cities (or can we?X)

84 What is bad about Nuclear Fission

85 Waste must be stored for thousands of years
Mining for fuel pollutes Boom!
