  7. Energy Resources • What are the main sources of nonrenewable energy? • What are the advantages and disadvantages of using nonrenewable energy resources? • How can individuals help manage nonrenewable resources wisely? Lesson 1 Reading Guide - KC

  8. Energy Resources • nonrenewable resource • renewable resource • nuclear energy • reclamation Lesson 1 Reading Guide - Vocab

  9. Sources of Energy Nonrenewable resources are resources that are used faster than they can be replaced by natural processes. resource from Latin resurgere, means “to rise again” Lesson 1-1

  10. Sources of Energy (cont.) Renewable resources are resources that can be replaced by natural processes in a relatively short amount of time. Lesson 1-1

  11. Sources of Energy (cont.) What are the main nonrenewable energy resources? Lesson 1-1

  12. Nonrenewable Energy Resources • Coal, petroleum (oil), and natural gas are fossil fuels. • Fossil fuels formed from the remains of prehistoric organisms. Lesson 1-2

  13. Much of the coal used today began forming more than 300 million years ago from the remains of prehistoric plants. Lesson 1-2

  14. Reservoirs of oil and natural gas often are under layers of impermeable rock. Lesson 1-2

  15. Nonrenewable Energy Resources (cont.) • There are advantages to using fossil fuels. • Changing the chemical energy of fossil fuels into electric energy is easy. • Fossil fuels are relatively inexpensive and easy to transport. Lesson 1-2

  16. Nonrenewable Energy Resources (cont.) • There are disadvantages to using fossil fuels. • Eventually, fossil fuels will be gone. • Obtaining fossil fuels disturbs environments. • Pollution occurs when fossil fuels are used. Lesson 1-2

  17. Nonrenewable Energy Resources (cont.) What is one advantage and one disadvantage of using fossil fuels? Lesson 1-2

  18. Nonrenewable Energy Resources (cont.) • Energy released from nuclear reactions is called nuclear energy. • Nuclear power plants produce electricity using nuclear fission. Lesson 1-2

  19. In a nuclear power plant, thermal energy released from splitting uranium atoms is transformed into electrical energy. Lesson 1-2

  20. Nonrenewable Energy Resources (cont.) • A small amount of uranium releases a large amount of energy. • Waste from nuclear power plants is radioactive and dangerous to living things. Lesson 1-2

  21. Managing Nonrenewable Energy Resources • Fossil fuels and nuclear energy provide about 93 percent of U.S. energy. • Although only about 4.5 percent of the world’s population lives in the United States, it uses more than 22 percent of the world’s total energy. Lesson 1-3

  22. Lesson 1-3

  23. Managing Nonrenewable Energy Resources(cont.) Reclamation is a process in which mined land must be recovered with soil and replanted with vegetation. Photograph by H.E. Malde, USGS Photo Library, Denver, CO Photograph by H.E. Malde, USGS Photo Library, Denver, CO Lesson 1-3

  24. Managing Nonrenewable Energy Resources(cont.) You can conserve energy by unplugging appliances when they are not in use and walking or riding a bike. Lesson 1-3

  25. Managing Nonrenewable Energy Resources(cont.) How can you help manage nonrenewable resources wisely? Lesson 1-3

  26. Fossil fuels include coal, oil, and natural gas. Fossil fuels take millions of years to form. Humans use fossil fuels at a much faster rate. Lesson 1 - VS

  27. Nuclear energy comes from splitting atoms, or fission. Nuclear power plants must be monitored for safety, and nuclear waste must be stored properly. Lesson 1 - VS

  28. It is important to manage nonrenewable energy resources wisely. This includes mine reclamation, limiting air pollutants, and conserving energy. Lesson 1 - VS

  29. Which resource do nuclear power plants use for fuel? A. coal B. natural gas C. oil D. uranium Lesson 1 – LR1

  30. Which term refers to energy released from atomic reactions? A. fossil B. nonrenewable C. nuclear D. renewable Lesson 1 – LR2

  31. Which term refers to resources that can be replaced by natural processes in a relatively short amount of time? A. fossil B. nonrenewable C. nuclear D. renewable Lesson 1 – LR3

  32. 1. Nonrenewable energy resources include fossil fuels and uranium. 2. Energy use in the United States is lower than in other countries. Do you agree or disagree? Lesson 1 - Now

  33. Renewable Energy Resources • What are the main sources of renewable energy? • What are the advantages and disadvantages of using renewable energy resources? • What can individuals do to encourage the use of renewable energy resources? Lesson 2 Reading Guide - KC

  34. Renewable Energy Resources • solar energy • wind farm • hydroelectric power • geothermal energy • biomass energy Lesson 2 Reading Guide - Vocab

  35. Renewable Energy Resources • Solar energy is energy from the Sun. • Active solar energy uses technology, such as solar panels, to gather and store solar energy. VisionsofAmerica/Joe Sohm/Photodisc/Getty Images Lesson 2-1

  36. Renewable Energy Resources(cont.) • Modern wind turbines can produce electricity on a large scale. • A group of wind turbines that produce electricity is called a wind farm. The McGraw-Hill Companies, Inc./John Flournoy, photographer Lesson 2-1

  37. Electricity produced by flowing water is called hydroelectric power. Lesson 2-1

  38. Renewable Energy Resources(cont.) Thermal energy from Earth’s interior is called geothermal energy. geothermal from Greek ge-, means “Earth”; and Greek therme, means “heat” Lesson 2-1

  39. Geothermal power plants use thermal energy from Earth’s interior and produce electricity. Lesson 2-1

  40. Renewable Energy Resources(cont.) Biomass energy is energy produced by burning organic matter, such as wood, food scraps, and alcohol. What are the main sources of renewable energy? Lesson 2-1

  41. Advantages and Disadvantages of Renewable Resources • Renewable energy resources will be available for millions of years to come and produce less pollution than fossil fuels. • Disadvantages associated with using renewable resources include that some are costly or limited to certain areas. Lesson 2-2

  42. Lesson 2-2

  43. Lesson 2-2

  44. Managing Renewable Energy Resources • Renewable energy currently meets only 7 percent of U.S. energy needs. • Most renewable energy comes from biomass. Lesson 2-2

  45. Managing Renewable Energy Resources (cont.) • Management of renewable resources often focuses on encouraging their use. • You can help educate others about renewable energy resources and make a difference by buying products that are made using renewable energy resources. Lesson 2-2

  46. Managing Renewable Energy Resources (cont.) What can you do to encourage the use of renewable energy resources? Lesson 2-2

  47. Renewable energy resources can be used to heat homes, produce electricity, and power vehicles. Lesson 2 - VS

  48. Advantages of renewable energy resources include little or no pollution and availability. • Management of renewable energy resources includes encouraging their use and continuing to research more about their use. Lesson 2 - VS

  49. Which is a disadvantage of using wind energy? A. availability in United States B. expense C. impact on birds D. pollution Lesson 2 – LR1
