The first chart illustrates energy consumption in an average Australian family, while the second chart displays the greenhouse gas emissions that result from this energy use.
Overall, heating and water heating are the two largest uses of energy in the average household; however, the highest percentages of greenhouse gas emissions result from water heating and other appliances.
As can be seen from the first graph, the majority of energy in an average Australian household is used by heating and water heating, at 42% and 30%, respectively. However, 15% of this energy is consumed by other appliances, which is twice the amount used for refrigeration, at 7%. Lightening and cooling use a very small amount of energy, at 4% and 2%.
If we turn to the percentage of greenhouse gas emissions, we can see that most of these emissions come from water heating and other appliances, at 32% ans 28%, respectively. While only 15% of these emissions result from heating, almost the same portion comes from refrigeration. The lowest proportion of these emissions comes from lightening and cooling, at only 2 and 8 percentage, respectively.
