The two pie charts illustrate how an average Australian household uses energy and the resulting greenhouse gas emissions from that energy consumption.
Overall, the energy consumption pie chart presents a predictable trend. It indicates that 42% of energy is used for heating, while only 2% is allocated for cooling. In contrast, the greenhouse gas emissions pie chart reveals an intriguing trend: 32% of emissions come from water heating, with only 3% emitted from cooling.
In the energy usage pie chart, it is evident that most energy is dedicated to heating (42%), followed by water heating, which accounts for nearly 30% of the total energy usage. Other appliances collectively use about 15%. Cooling, lighting, and refrigeration make up a minimal portion of energy usage at 2%, 4%, and 7%, respectively.
The greenhouse gas emissions pie chart similarly highlights that the majority of emissions stem from water heating (32%), followed closely by other appliances, which contribute 28%. Heating and refrigeration have nearly identical contributions, at 15% and 14%, respectively, which is substantial when considered in total. Lastly, cooling and lighting represent a small fraction of the emissions at 3% and 8%, respectively.
