The first pie chart illustrates how energy is consumed in a typical household in Australia. The second pie chart illustrates how much greenhouse gas is released as a consequence of this energy use.
Overall, heating accounts for most of the energy use, while cooling accounts for the least. In terms of greenhouse gas emissions, water heating contributes the most, whereas cooling contributes the least.
For power consumption, both types of heating contribute to more than 70% of the total, with heating accounting for just over 40% and water heating 30%. Refrigeration, lighting, and cooling together constitute 13% of energy use, with cooling comprising 2%, which is the least among the given categories. Other appliances make up 15% of the total energy consumption.
Although heating has the greatest share in energy use, it only constitutes 15% of the greenhouse gas emissions. In contrast, water heating accounts for the most emissions, with just above 30%. A quarter of the total share of emissions is taken by refrigeration, cooling, and lighting, with cooling having the lowest share again, with 3%. The remaining 28% of the emissions is contributed by other appliances.
