The pie charts illustrate the proportions of household energy consumption and greenhouse gas emissions for seven different purposes in Australia.
Overall, while heating accounts for the largest share of household energy use, heating and cooling generate the highest proportion of greenhouse gases. Notably, the distribution of energy consumption and gas emissions differs significantly across the categories.
In terms of energy consumption, heating constitutes the largest portion, at 40%, followed by water heating, which makes up 23%. Other appliances account for 15%, while refrigeration and lighting contribute 7% and 4%, respectively. Cooking and standby devices have the smallest shares, at 5% and 3%.
Conversely, greenhouse gas emissions are dominated by heating and cooling, which together make up 38%. Water heating is the second-largest contributor, at 25%, while other appliances account for 16%. Refrigeration and lighting both produce 7% of emissions. Cooking and standby devices generate the least, contributing just 4% and 3%, respectively.
