  1. Energy For Human Use HOW MANY RESOURCES CAN PRODUCE ELECTRICITY?

  2. What does Energy Resources mean? • "Energy Resources" is NOT the same thing as “Forms of energy". • "Types of energy" or “Forms of energy” means "kinetic energy", "chemical energy“. Thermal, • "Energy Resources" is about ways of getting energy so we can generate electrical power.

  3. Energy Resources Renewable Resources Non-Renewable Resources • Natural resources that cannot be replaced or that can be replaced only over thousands or millions of years. • Natural resources that can be replaced over a relatively short period of time.

  4. Energy Resources: Place each one in the correct heading. Renewable Resources Non-Renewable Resources Natural Gas Oil Inexhaustible Resources

  5. Non – Renewable Resources Oil Coal Natural Gas Nuclear Oil, coal and Natural Gas are all Fossil Fuels

  6. What is the original form of energy for coal and other fossil fuels?

  7. What is the original form of energy for coal and other fossil fuels? THE SUN’s RADIANT ENERGY

  8. Nuclear What part of the atom will split to release heat?

  9. Nuclear What part of the atom will split to release heat? The NUCLEUS

  10. Nuclear energy is stored in the ___________ atoms. Nuclear fusion changes the nucleus of the atom and releases ____________ and ___________.

  11. Nuclear energy is stored in the _hydrogen_ atoms. Nuclear fusion changes the nucleus of the atom and releases _radiant energy__ and _thermal energy__.

  12. Uranium atoms store the _______________ energy. The atoms are ________ to release _________ and _________. This process also released a toxic waste product called ____________.

  13. Uranium atoms store the __nuclear_ energy. The atoms are _split__ to release _radiant__ and _thermal_. This process also released a toxic waste product called _radiation_.

  15. Non – Renewable Resources Oil Coal Natural Gas Nuclear Oil, coal and Natural Gas are all Fossil Fuels

  16. 5 - Renewable Resources Water Hydroelectric Power Biomass Organic or Living Matter Wind Geothermal Earth’s Heat Solar

  17. Inexhaustible Resources These three can be called Inexhaustible Resources or Renewable Resources. Wind Geothermal Earth’s Heat Solar

  18. GEOTHERMAL =Energy from Earth’s heat Geo means _______ Earth Thermal means _______ HEAT

  20. Pump in water…………………………………..to make STEAM…….

  21. Now use the steam to turn a ___________ to turn a ____________ to make _________________. Geothermal HOT!

  22. Now use the steam to turn a _TURNBINE__ to turn a GENERATOR_ to make _ELECTRICITY_. Geothermal HOT!

  24. Mechanical (1791-1867) Electrical Thermal

  25. Michael Faraday(1791-1867) • He figured out you can spin a magnet in a coil of wire and it makes electricty....its called a “generator”.

  26. Name the energy transformations in the picture. Kinetic Mechanical Electrical

  27. Biomass or Biofuels Bio means _______

  28. Biomass or Biofuels Bio means _LIFE_ These fuels are made from recently living matter…corn, sugar cane, garbage, algae…..

  29. Harvesting biomass fuel Biofuels or biomass will also release _______________ into the atmosphere when _____________________. But it is less pollution than ____________________.

  30. Harvesting biomass fuel Biofuels or biomass will also release CO2 Carbon dioxide into the atmosphere when _BURNED_. But it is less pollution than _FOSSIL FUELS.

  32. Hydropower= Hydro means __

  33. Hydropower= Hydro means water

  34. Hoover Dam www.unitedstreaming.com

  35. A continual flow of water makes HYDRO POWER a reliable source of energy as long as water is backed up behind the dam. What is reliable mean? Is this an advantage or disadvantage? Grand Coulee Dam

  36. What is reliable mean? You can count on it. You can rely on it. Is this an advantage or disadvantage? ADVANTAGE Grand Coulee Dam
