energy usage and greenhouse gas emissions
The two pie charts depict the percentage of energy usage and the generation of greenhouse emissions by six distinct energy sectors in a typical Australian family.
Overall, what stands out is that Heating accounts for the greatest energy consumption, while Water Heating contributes the largest segment to the greenhouse gas emissions. Notably, Cooling is the smallest part of all.
Regarding the amount of energy consumed, Heating holds the lion's share, with 42%, which is 12% larger than the rate of Water Heating. Besides, the percentage of Refrigeration makes up just 7%, which is about twice as low as that of Other Appliances (15%). By contrast, the figure for Lighting doubles that for Cooling, registering 4% and 2%, respectively.
Concerning the greenhouse gas emissions, Water Heating's production comprises the largest proportion, at 32%, followed closely by Other Appliances counterpart, gaining 28%. There is a slight gap between the data on Heating (15%) and Refrigeration (14%). Meanwhile, Lighting and Cooling occupy the least fraction of the total emissions output, with 11% collectively.
