Sample Report 1
The provided diagrams illustrate the distribution of energy usage and greenhouse gas emissions within Australian households. Each chart offers insights into various components contributing to energy consumption and the resultant environmental impact.
Overall, the diagrams reveals significant trends: heating and water heating dominate household energy use, while water heating is the principal source of greenhouse gas emissions. Other household appliances also contribute notably to both energy consumption and emissions.
Diving deeper, the left diagram shows that heating accounts for a substantial 42% of total energy usage, while water heating consumes another 30%. These two categories are the most energy-intensive, underscoring their major role in domestic energy expenditure. Other appliances represent 15% of the energy use, followed by refrigeration at 7%. The smallest shares are attributed to lighting and cooling, which make up 4% and 2% respectively.
Turning to the greenhouse gas emissions in the second diagram, water heating is again at the forefront, responsible for 32% of emissions. Interestingly, while other appliances consume less energy than heating, they are almost as significant in terms of emissions, accounting for 28%. Heating contributes to 15% of emissions, matching the output from refrigeration. Lighting and cooling collectively are responsible for the remaining 11% of greenhouse gases emitted, highlighting their lower relative impact on the environment.

Sample Report 2
The two pie charts depict how energy is consumed in Australian households across six categories and the corresponding greenhouse gas emissions. Overall, heating consumes the most energy, while water heating is responsible for the largest share of greenhouse gas emissions.
In terms of energy consumption, heating accounts for the largest share at 42%, followed by water heating at 30%. Other appliances account for 15%, while refrigeration, lighting, and cooling use significantly smaller proportions, at 7%, 4%, and just 2%, respectively. Cooling, in particular, stands out as the category with the lowest energy usage, substantially lower than all others.
However, the second chart illustrates that energy consumption does not directly correlate with greenhouse gas emissions. Despite heating being the largest consumer of energy, its greenhouse gas emissions are relatively low at 15%, ranking third overall. In contrast, water heating, which consumes 30% of energy, contributes the highest percentage of emissions at 32%. Other appliances are responsible for 28% of greenhouse gases, making them the second-largest contributor, despite using less energy than heating and water heating.
Refrigeration uses 7% of energy but generates a comparatively high 14% of emissions, doubling its energy share. Lighting and cooling, while minor consumers of energy at 4% and 2%, produce 8% and 3% of greenhouse gases, respectively. Although these categories have a minimal impact, the emissions from refrigeration and other appliances are disproportionately higher compared to their energy usage.

Sample Report 3
The initial visual representation outlines the typical energy consumption of an average household in Australia, while the latter visualization showcases the greenhouse gas emissions stemming from this energy usage.
In general, while heating and water heating are responsible for a notable portion of energy utilization, the majority of greenhouse gas emissions arise from water heating and other household appliances.
Water heating and heating systems account for the largest portion of energy usage, comprising 42% and 30% respectively. Other appliances, on the other hand, consume approximately 15% of the total, which is nearly twice as much as the amount of energy used for refrigeration. Cooling and lighting, respectively, account for very small percentages of energy consumption, at 2% and 4%.
Interestingly, water heating is also a leading cause of greenhouse gas emissions, accounting for almost one-third of total emissions. The second-largest contributor to emissions comes from other household appliances, which account for 28% of the total. Heating, surprisingly, is responsible for only 15% of total emissions, which is approximately the same as that for refrigeration. The remaining 11% of the total Australian households' greenhouse gas emission is the result of cooling and lighting.
Sample Report 4
The pie charts show how much energy Australian residents use and what proportion of greenhouse gas emissions they produce. The units are expressed as percentages and the categories are arranged into five groups.
Overall, the majority of residential energy consumption in Australia was for heating, followed by water heating and other appliances. The biggest source of greenhouse gas emissions, meanwhile, is not just heating, rather water heating and other equipment.
According to the data, families in Australia consume 42% of their total energy for heating. Additionally, the use of other appliances and water heating is 15% and 30%, respectively. Therefore, only the remaining 13 percent energy is jointly used by the other three areas, refrigerator, lighting, and cooling.
However, even though homes use the most energy for heating, the largest levels of greenhouse gas emissions—32 and 28 percent, respectively—come from water heating and other equipment. The quantity of gas released by heating and refrigeration is almost equal at 15% and 14%, respectively. However, cooling always remains the lowest both in terms of energy use (2%) and greenhouse gas emission (3%).
