The Law of Energy states that energy cannot be created or destroyed, it can only change form. When heat travels through a solid without the material itself moving, the process is called . Solar and wind energy are examples of energy sources because they are replenished naturally. In a household circuit, appliances are wired in so each device receives the same of 240 volts. Green is produced using renewable electricity to split water molecules. Australia's CO₂ per person are among the highest in the world, largely due to coal-fired power and energy-intensive industries. The of an energy conversion is calculated by dividing the useful energy output by the total energy input.
