The two pie charts illustrate the consumption of energy and the emissions that it produces in a typical Australian family.
Overall, heating constitutes the biggest proportion of energy use, while in terms of emissions the water heating leads. In contrast, the cooling utilizes less energy as well as releases the least of greenhouse gases.
Moving on to the details, heating takes the largest amount of energy in Australian households, which constitutes 42%, although it produces around 30 percent less of emissions. While water heating contributes to around one third of consumption, it makes 32% of harmful emissions. In terms of other appliances, they account for 28% of greenhouse gas emissions, but use up nearly twice as less energy.
Notably, the usage of the refrigerator and lighting is two times less than what they emit, the former being 7 and 14 percent, the latter being 4% and 8%. Meanwhile, cooling uses up and forms approximately the same proportion of gases at 2% and 3% respectively.
