Mr. Fleming

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.

 What are different sources of energy?  How to do they transfer to make electricity?

 Electricity Production Electricity Production

 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
