The pie charts illustrate the consumption of energy and greenhouse gas emissions, which resulted from the energy use in an average Australian household.
It is evident that the Australian household used the highest amount of energy for heating, which is also the major source of greenhouse gas emission and utilised a minimal amount of power for cooling, which is responsible for a fraction of the gas output.
Australian household mostly use electricity for heating, which is substantially higher than others at 42%, followed by water heating at 30%. Meanwhile, other appliances account for 15%, which is twice as much as refrigeration, 7%. In addition, they use only 2% of energy for cooling, which is half of lighting, 4% and significantly smaller than others. In comparison, water heating accounts for the lion’s share of greenhouse gas emissions at 32%, which is followed by other appliances, 28%. Furthermore, while most energy is used for heating, it only produces less than half of the greenhouse gas at 15% than water heating does. Refrigeration accounts for 14%, which is two times larger than lighting, 8%. In contrast, cooling causes 3% of the greenhouse gas emissions, which is the least among all of the sources.
