How is electricity made?
Firstly, to generate electricity, you’ll require a fuel source, such as coal, gas, hydropower or wind.
In Australia, most of our electricity supply is generated from traditional fuels, such as coal and natural gas, with around 14 percent coming from renewable energy sources.1
Regardless of the chosen fuel, most generators operate on the same proven principle: turn a turbine so that it spins magnets surrounded by copper wire, to get the flow of electrons across atoms, which in turn generates electricity.
Coal and gas work in similar ways; they are both burned to heat water, which creates steam and turns the turbine.
Renewable energy sources such as hydropower and wind operate slightly differently, with either the water or the wind being used to turn the turbine, and generate the electricity.
Solar photovoltaic panels take a different approach again: they generate electrical power by converting solar radiation into electricity using semi-conductors.
