Pie chart

The two pie charts illustrate the proportion of average energy which is consumed for various purposes by an Australian household and how much the greenhouse gas emission which is from this energy use. Overall, the energy use for heating is higher than others. While most greenhouse gas emissions result from water heating and other appliances.

Looking at the first chart, it can be seen that percentage of average energy used for heating in a household in Australia occupies nearly a half of the piechart, at 42%. Besides that, 30% is the average energy used for water heating. While other appliances consume 15%, the total percentage of energy is consumed for refrigeration; lighting and cooling are very small, at 13%.

In the second pie chart, it is clear that the percentage of water heating and other appliances are also major sources of greenhouse gas emissions making up over a quarter of total emissions for each purpose at 32% and 28% of the total respectively. Heating surprisingly is only responsible for 15% of total emissions and this figure is the same as that for refrigeration. However, the remaining 11% result from lighting and cooling.
