  1. Reviewing Key Issues

  2. Energy

  3. Where does our energy come from? Approximately 95% of electricity generated in Victoria currently comes from burning coal

  4. Australia’s total emissionsSource: State and Territory Greenhouse Gas Inventories 2006, published by the Australian Government (emissions from electricity generation) (Emissions from extracting oil & gas)

  5. If the atmosphere warmed by 2°C Australian ecosystems and coastal communities would be seriously affected, and we’d struggle to make sure we had enough water If it warmed by 3°C our agriculture and forestry would be in trouble. If it warmed by 4°C infrastructure, sustainable development and tourism would be in trouble, climate change would be causing health problems which would be causing deaths, and we’d be struggling to make sure we had a reliable energy supply.

  6. Where does most energy get used at home?

  7. Energy used in the home Source: Victorian Energy Efficiency Action Statement, Department of Sustainability and Environment, 2006

  8. Waste

  9. 490 kg garbage per house per year199 kg per person per year 490 kg

  10. The waste hierarchy 1 Maximum conservation of resources 2 Reusing materials 3 Recycling & reprocessing materials 4 Energy recovery before disposing 5 No conservation of resources

  11. Water

  12. How much water do we use? • Average daily water use per person info for your area is available from:www.ourwater.vic.gov.au/saving/towns/household-water-consumption • E.g. Ballarat 151L/person/day; Geelong 178L; Melbourne 159L; Mildura 436L

  13. Where do we use our water? Average household water use Laundry 22% Bathroom 51% Kitchen 8% Garden 19%
