The pie charts illustrate the distribution of energy consumption for different purposes and the corresponding greenhouse gas emissions in an average Australian household.
Overall, while heating is the most significant consumer of energy, water heating contributes the largest share of greenhouse gas emissions.
Heating accounts for 42% of the energy consumed by an Australian household, making it the most substantial figure in the chart. Water heating follows at 30%. In contrast, other appliances consume only 15% of the total energy, while refrigeration, lighting, and cooling account for 7%, 4%, and 2%, respectively.
In terms of greenhouse gas emissions, water heating is responsible for 32% of the total, making it the largest contributor. Energy used by other appliances generates 28% of the emissions. By comparison, the percentages for heating, refrigeration, and lighting are 15%, 14%, and 8%, respectively. Cooling, on the other hand, contributes just 3% to the overall greenhouse gas emissions.
