  2. ELECTRICITY & RENEWABLE RESOURCES

  3. Part 1: Electricity and Renewable Energy Most electricity sources have three main parts The fuel source The turbine The generator

  4. Part 1: Electricity and Renewable Energy A simple generator * * • Larger generators use the same principle * Pictures from http://www.childrensuniversity.manchester.ac.uk/interactives/science/energy/electricity.asp

  5. Part 1: Electricity and Renewable Energy • COAL, OIL OR GAS • Fuel burnt to turn water to steam • Steam turns turbine • Turbine turns generator *

  6. Part 1: Electricity and Renewable Energy • HYDRO-ELECTRIC POWER • Lots of water dropped through large wheel • Wheel turns generator *

  7. Part 1: Electricity and Renewable Energy • NUCLEAR POWER • Fuel of radioactive uranium • Uranium atoms are split, creating radiation and heat • Heat used to make steam *

  8. Part 1: Electricity and Renewable Energy • BIOMASS POWER • Burn trees, shrubs, manure, rubbish; or burn gases from these • Creates steam *

  9. Part 1: Electricity and Renewable Energy * • GEOTHERMAL • Uses steam from hot water reservoirs deep below the Earth

  10. Part 1: Electricity and Renewable Energy * • SOLAR POWER • Uses special panels called “photovoltaic cells” • Cells produce electricity when sunlight falls on them

  11. Part 1: Electricity and Renewable Energy * • TIDAL AND WIND TURBINES • Wind or ocean tides rotate blades which turn generator *

  12. Part 1: Electricity and Renewable Energy • Electricity generation is a major CO2 emissions culprit • Some methods produce more than others • Some produce no CO2 at all

  13. Part 1: Electricity and Renewable Energy • NON-RENEWABLE • Fuel will run out • Most produce greenhouse gases • RENEWABLE • Fuel won’t run out • Most don’t produce greenhouse gases

  14. WELCOME TO THE UNITED NATIONS CLIMATE CHANGE ASSEMBLY

  15. BOOOOOOO!

  16. Oil won't be cheap forever!

  17. Ooooooooooohhh!

  18. APPLAUSE

  19. BOOOOOOO!

  20. Hooray for Denmark!

  21. Ooooooooooohhh!

  22. YEAH That's Right!

  23. Aaaaaah

  24. Ooooooooooohhh!

  25. Solar Power is FOREVER! Solar Power is FOREVER!

  26. SAY ANY LINE! Nuclear Power! Nuclear Power! Oil Power! Oil Power! Coal Power! Coal Power! Coal Power! Solar Power! Solar Power!Hydro Power! Hydro Power! Biomass Power! Biomass Power! Wind Power! Wind Power!

  27. WHICH ONE IS BEST?

  28. Case Study from an EWB Project – Sustainable Energy Options for the Uluru Children’s Home(that’s Uluru in India, not Australia!!)

  29. Uluru Children’s Home –Project Introduction AIMS: • Reliability of Power Supply • Undertake Energy Audit • Identify Sustainable Energy Options

  30. Information gatheringOverall Energy breakdown (MJ/yr)

  31. UCH Cooking Gas Options

  32. UCH - Sustainable Cooking Options • Community Solar Dish Cooker

  33. UCH - Sustainable Cooking Options • Biogas system Cooking gas can be produced from food scraps, cow dung and other agro-waste

  34. UCH Electricity options

  35. UCH - Electricity breakdown • 36kWh/day average electricity demand • Cost of electricity per year Rs. 58,072 or AUS $1760

  36. Energy Efficiency Options • Replace remaining incandescent bulbs with energy efficient fluorescent lights • 70% reduction in lights left on at night • Reduce water pumping by fixing leaking bore water tank • Replace the fridge seal in UCH kitchen

  37. Sustainable Electricity Options Two power sources were suggested, to power electricity use at the Uluru Childrens’ Home: • Solar • Wind
