Modern society is geared to using electricity. Electricity has characteristics that have made it uniquely suited for powering a highly technological society. There are many energy sources that can be readily converted into electricity. In Australia, most power plants burn a fuel such as coal or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively easy to distribute. Electricity authorities use high voltage transmission lines and transformers to distribute electricity to homes and industries around each state. Voltages from power stations can be as high as 500 000 volts but by the time this reaches homes, the electricity has been transformed to 240 volts. While it is relatively economical to generate electric power at a steady rate, there are both financial and environmental issues that should be considered when assessing the long-term impact of supplying commercial and household power.
