Farmers rely on this form of precipitation.
What is rain?
Coming in either thermal, or photoelectric varieties, Australia is well suited to making use of this kind of renewable energy.
What is solar energy?
Coming from oil reserves, this fossil fuel commonly powers trucks, mining equipment and more.
What is diesel?
This metal is important in the building industry and many more. It can be picked up with a magnet.
What is steel/iron?
This type of rock is formed from cooling magma
What is igneous rock?
This form of precipitation might occur when it's very cold.
What is snow?
This type of energy relies on the gravitational potential energy of an elevated water store.
What is hydroelectric energy?
This fossil fuel is the most common fuel source for passenger cars in Australia.
What is petrol?
This metal is important in the aeronautical industry and many more. A magnet won't pick it up, but a fast moving magnet can be used to flick it off a conveyor due to magnetic induction.
What is Aluminium?
This type of rock is built up of layers over time.
What is sedimentary rock?
This process in the water cycle is a change of state from liquid to gas.
What is evaporation?
What is geothermal energy?
Australia is traditionally reliant on this as an energy source and export.
What is coal?
Highly conductive and commonly used in electrical cabling in buildings, this metal is found in chalcopyrite.
What is copper?
This type of rock is made from rocks that are changed by heat and pressure.
What is metamorphic rock?
These water stores hold most of the water on Earth
What are the oceans?
Wind, water, or other flowing liquid can spin these for input to a generator.
What are turbines?
Proposed as an alternative energy source for electricity base loads, Australia's large reserves of this and stable landmass vie with safety and other concerns around this energy source.
What is uranium/nuclear energy?
This rare earth metal is important for the batteries found in smartphones.
What is lithium?
This common building material is made using rocks, water and a binder made from rocks.
What is concrete?
Plants take water from the soil to the air through this process.
What is transpiration?
The power input to a renewable energy system that is 30% efficient and outputs 6kW.
What is 20kW?
This most volatile hydrocarbon found in oil reserves, is also found in cow burps.
What is natural gas/methane?
This expensive metal is used to make lightweight and strong alloys used in high end engine parts, bike parts, skateboard axles and more.
What is titanium?
This pairing of mined ore and processed metal could one of many pairings.
