Where does our electricity come from?Most of us have access to electricity in our homes and at school. In Australia most electricity is produced in power plants fuelled by coal, natural gas or running water (hydroelectricity). These sources of energy1 are plentiful, at least for now, and don’t cost as much as some other forms of electricity generation. In many parts of the world, electricity is produced in nuclear power plants2. Some families make choices about the source of the electricity they use. Discussion point
