The pie charts give information about the percentage of energy consumption and the resulting greenhouse gas emissions in Australian houses.
Overall, it is evident that heating and water heating stand out as the primary contributors to energy consumption, whereas water heating and other appliances emerge as the major sources of greenhouse gas emissions.
Looking at the details of energy consumption first, heating and water heating collectively accounted for the largest portion, with 42% and 30%, respectively, of the overall energy use in Australia. In contrast, other appliances contributed only a quarter of the total energy usage, while the remaining purposes, namely refrigeration, lighting, and cooling, make up a modest 13% overall.
In terms of emissions stemming from these activities, it is notable that the figures do not always correlate with energy usage. Despite water heating and other appliances being the second and third largest energy consumers, they surpass heating as the foremost contributors to emissions, representing 32% and 28%, respectively. Heating, on the other hand, constitutes a mere 15% of the overall share, followed by refrigeration at 14%, with the remaining categories contributing a combined 11%.
