How energy is used in an average Australian household How energy is used in an average Australian household as the picture shown above, we can easily find that 72% energy is used for heating in an average Australian household (42% heating and 30% water heating) , which is the biggest part compared to others. The rest of other energy is used by refrigeration(7%), lighting(4%), cooling(2%) and other appliances(15%). Now let’s check the second chart: we can also find that heating still occupy the big part about 47% in Australian household green house gas emissions(15%heating and 32% water heating). By the way, refrigeration(14%) and other appliances(28%) also take a not small part as well as 8% lighting,3% cooling in gas emissions. In short, as the emissions of global greenhouse gas are becoming more , we should take some actions to save our environment like reduce heating by coal or natural gas which will produce more greenhouse gas. Furthermore, using more energy efficient appliance will also play a vital role for energy conservation
