The pie charts illustrate how households in Australia consume energy and the equivalent greenhouse gases emitted from their energy-consuming activities.
Overall, Australian households use the majority of energy for heating, either their homes or water, which in turn releases the largest amount of greenhouse gas emissions.
One of the most significant points in the data is that, while heating accounts for 42% of energy consumption, it is only responsible for 15% of gases releasing into the environment. This contrasts sharply with other appliances, which use a merely 15% of energy, yet comprising approximately 30% of greenhouse gases. Water heating consumes about a third of the total energy and makes up a nearly identical figure of gas emissions.
The figures for other activities including cooling, refrigeration, and lighting were rather insignificant. To be precise, a tiny 2% of energy is used to keep Australian families cool and another 7% to preserve their food in the refrigerators, causing 3% and 14% of gas emissions respectively. The remaining shares (4% of energy and 8% of gases) belong to lighting category.
