The two pie charts illustrate the distribution of energy consumption in an average Australian household and the resultant greenhouse gas emissions.
Overall, heating uses the most energy, while water heating creates the most greenhouse gases. Cooling uses and emits the least in both categories.
The first chart shows that the most energy is used for heating, which takes up 42% of the total. Water heating comes next at 30%. Other appliances use 15% of the energy, whereas refrigeration uses 7%.Lighting and cooling contribute the least, with 4% and 2%.
In contrast, the second chart reveals that water heating is the largest contributor to greenhouse gas emissions at 32%, despite using less energy than heating. Other appliances are responsible for 28% of emissions, which is a higher percentage than their energy use. Heating accounts for 15%. Refrigeration makes up 14%, lighting 8%, and cooling the least at 3%.
