    Study Notes

    Renewable Resources

    • Renewable energy comes from natural sources that replenish faster than humans use them
    • Examples include solar, wind, hydro, and geothermal
    • Natural resources exist independently of human actions

    Non-renewable Resources

    • Resources that cannot be replaced once used
    • Examples include coal, oil, gas, nuclear energy, and iron

    Resource Extraction

    • Process of removing resources from the Earth
    • Methods vary depending on the resource (mining, drilling, harvesting)

    Waste Management

    • Waste is a product or substance no longer needed
    • Ecological footprint measures resource consumption and waste generation
    • Infrastructure supports societal function and involves basic physical and organisational structures

    Ecological Footprint

    • Measures resource consumption and waste generation
    • Indicates the rate at which resources are consumed and waste created

    Infrastructure

    • Basic physical and organisational structures for any society or enterprise
    • Includes facilities, services and other necessary structures for economy
    • Vital for any society or enterprise to work properly

    Recyclable Materials

    • Materials processed to make new materials/objects
    • Improves waste management efficiently, protecting the environment

    Biodegradable Materials

    • Materials that break down naturally after interacting with biological factors
    • Encourages waste management efficiency and environmental protection.

    Sustainability

    • Studying the dynamic relationship between humans and the environment
    • Ensuring natural resources are maintained for long term usage and environmental protection

    Habitat

    • Natural environment or home to plants, animals and other organisms
    • Essential for preservation and thriving for organisms

    Pollution

    • Introducing substances or forms of energy into the environment at rates faster than it can disperse safely.
    • Negative consequence of human action, harming the environment.

    Initiatives

    • An introductory or step, and an initiative taken to start a project, or to solve a problem.

    Inquiry Question 1: How are Australia's natural resources extracted, used and managed?

    • Renewable resources in Australia: agricultural (terrestrial and aquatic)

    Agricultural Resources- Terrestrial

    • Farming in Australia is worth $60 Billion
    • Farmers export 77% of their produce, contributing $44.8 Billion to the economy
    • Agriculture-related jobs employ 1.6 million Australians

    Agricultural Resources- Aquatic

    • Aquaculture farms aquatic animals and plants for food
    • Australia produces 230,000 tonnes of seafood annually
    • Fisheries and aquaculture contribute $2.4 billion to Australia's economy.
    • Indigenous Australians farmed eels for at least 6000 years
    • Aquatic organisms are now farmed in salt/fresh water cages and ponds.

    Water as a Resource

    • Australia is the driest inhabited continent
    • Water use in Australia is high due to agriculture and other consumption
    • Water quality is good but vulnerable to droughts and low rainfall, which results in water shortages

    Water Consumption

    • Household use, livestock use, and irrigation use are the main users of water
    • Groundwater abstraction and total water withdrawal figures are shown, showing an increase over time.

    Water Sources

    • Rivers and reservoirs provide water for drinking, agriculture, industry, and recreation
    • They support ecosystems across Australia
    • Dams provide water for human consumption

    Energy Sources

    • Electricity generation in Australia in 2017:
      • Black coal 47%
      • Natural gas 21%
      • Renewables 15%
      • Small-scale solar PV 20.7%
      • Biomass 9.3%
      • Wind 32.4%
      • Large-scale solar PV 2%
      • Hydro 35.6%
      • Oil 2%
    • Renewable energy sources make up approximately 18% of Australia's total energy consumption

    Energy Sources Location

    • Map showing potential energy source locations across Australia
    • Identified resources include tidal, wave, solar, geothermal, and wind

    Types of Renewable Energy

    • Tidal power: uses turbines to harness tidal changes
    • Wave energy: uses equipment placed on water surface to capture and convert wave movements
    • Advantages/Disadvantages of each type are considered
    • Locations where required resources are available

    Other Information

    • There is a list of other energy and water resources
    • Study notes cover resource locations, types, and environmental impact.
