The first pie chart presents the distribution of energy consumption in an average Australian household, while the second chart illustrates the proportion of greenhouse gas emissions generated from this energy usage.
Overall, it is clearly evident that the highest energy consumption is due to heating, whereas the highest greenhouse gas emission is a result of water heating.
The consumption of energy in Australia is dominated by the use of heating and water heating machines, with approximately 42% and 30%, respectively. The other data are separated into four categories: refrigeration, cooling, lighting, and others, with the least usage for cooling, which accounts for only a tiny portion of 2%.
Although heating is the most frequently used energy, the greenhouse gas emissions from heating are less than half of water heating emissions, recorded at 15% compared to 32% for water heating. While cooling usage aligns with its emissions, a distinct pattern emerges for lighting and refrigeration. The emissions from these two categories are twice as high as their energy consumption, increasing from 4% to 8% for lighting and 7% to 14% for refrigeration.
