  1. Sources of Energy Mr. Fleming

  2. Standards D.7 Explain how heat is used to generate electricity. D.8 Describe the availability, current uses and environmental issues related to the use of fossil and nuclear fuels to produce electricity. D.10 Describe the availability, current uses and environmental issues related to the use of hydrogen fuel cells, wind and solar energy to produce electricity.

  3. Essential Questions • What are different sources of energy? • How to do they transfer to make electricity?

  4. How Electricity is Generated? • Electricity Production

  5. Sources of Energy: Renewable vs Non-Renewable • Fuel Sources Include • Renewable • Energy that is naturally produced as fast as it is used. • Example: Biomass, Sun, Water, Wind • Non-renewable • Energy that gets used faster than its produced. • Examples: Fossil Fuels (Coal, Oil, Natural Gas), Uranium

  6. Forms and Sources of Energy The energy we use in the United States is mainly provided by the following sources of energy. Write the form of energy – how the energy is stored or delivered – for each of the sources on the line to the right of the source. Renewable Nonrenewable Biomass ______________ Petroleum ________________ Hydropower __________ Natural Gas _______________ Geothermal ___________ Coal _____________________ Wind ________________ Uranium __________________ Solar ________________­ Propane ___________________ What percentage of the nation’s energy is provided by each form of energy? By renewable? Nonrenewable? Chemical _____________ Renewable ________________ Nuclear _______________ Nonrenewable _____________ Motion _______________ Thermal ______________ Radiant ­ ______________

  7. Forms and Sources of Energy The energy we use in the United States is mainly provided by the following sources of energy. Write the form of energy – how the energy is stored or delivered – for each of the sources on the line to the right of the source. Renewable Nonrenewable Biomass Chemical Petroleum Chemical Hydropower Mechanical Natural Gas Chemical Geothermal Thermal Coal Chemical Wind Mechanical Uranium Nuclear Solar Radiant Propane Chemical

  8. What percentage of the nation’s energy is provided by each form of energy? By renewable? Nonrenewable? Chemical 88 % Renewable 7.4 % Nuclear 8.5 % Nonrenewable 92.6 % Mechanical 3.0 % Thermal 0.4 % Radiant 0.1 %
