Earth Ed Renewable Energy

  1. 1. Renewable Energy
  2. 2. Renewable Energy Purpose of session: • To improve our understanding of renewable energy‟s contribution to Australia‟s energy mix. • To improve our understanding of the types of renewable technologies that exist. • To provide two simple practical ideas for investigating renewable energy in the classroom.
  3. 3. Renewable Energy “Renewable” • Capable of being renewed „Renew-a-Bean‟ (National Renewable Energy Laboratory)
  4. 4. Renewable Energy Renew-a-Bean Consumption Level Year 1 Year 2 Year 3 Year 4 Year 5 Year 6 Year 7 Year 8 Year …. Beans Removed 10 10 10 10 10 10 10 10 10 Beans Remaining % Renewable % Non- Renewable AusVels Level 6: Make connections between equivalent fractions, decimals and percentages
  5. 5. Renewable Energy AusVELS AusVELS Science Level 6: Energy from a variety of sources can be used to generate electricity Scientific understandings, discoveries and inventions are used to solve problems that directly affect peoples’ lives Decide which variable should be changed and measured in fair tests and accurately observe, measure and record data, using digital technologies as appropriate Suggest improvements to the methods used to investigate a question or solve a problem
  6. 6. Renewable Energy Are all renewable sources also sustainable? • Environmentally? • Economically? • Socially?
  7. 7. Renewable Energy So where‟s Renewable Energy at? Q: What percentage of Australia‟s electricity is delivered from renewable sources? A: 13 % Australia currently has a commitment under the RET (Renewable Energy Target) to achieve 20% by 2020.
  8. 8. Renewable Energy Our Demand for Power
  9. 9. Renewable Energy But electricity prices have….. …risen. Why?
  10. 10. Renewable Energy Rising electricity costs: • Carbon Tax? • RET?
  11. 11. Renewable Energy Peak Demand
  12. 12. Renewable Energy Wind Energy
  13. 13. Renewable Energy Wind Energy
  14. 14. Renewable Energy Wind Energy What about the environmental impacts of a wind farm? !! • Manufacture of components • Roads development • Servicing • Concrete footings How do we compare the impacts?
  15. 15. Renewable Energy Wind Energy Full LCA (Life Cycle Analysis) conducted of Waterloo Wind Farm • Waterloo, South Australia • 37 3.0MW Turbines • 111 MW capacity • 25 year life

  20. 20. Renewable Energy Geothermal
  21. 21. Renewable Energy Household Solar
  22. 22. Renewable Energy Household Solar
  23. 23. Renewable Energy Household Solar
  24. 24. Renewable Energy Solar Water Heating The electricity used to heat water is the largest single source of greenhouse gas emissions from the average Australian home, producing almost a quarter of household emissions.1 1.
