The provided pie charts demonstrate the percentages of consumed energy for various domestic purposes in a typical household in Australia and the resultant greenhouse gases.
It can be explicitly observed that while heating stands as the pinnacle in terms of energy consumption, cooling languishes at the opposite end. Additionally, there is no considerable discrimination between the proportion of used energy and emitted gases for cooling in comparison with the others.
Compared to 42% of required energy usage, heating registers a significantly lower discharging greenhouse gases at 15%. Water heating, in contrast, secures the second position with 30% of energy used but is just responsible for 32% greenhouse gases emitted. The respective percentages of the energy consumption and greenhouse gas emission of cooling are 2% and 3%.
Lighting, other appliances and refrigeration combined occupy a quarter of total energy consumed in an average Australian household. There is a marked disparity between the proportion of used energy and resulting greeenhouse gases in the case of refrigeration and lighting, with the latter being double that of the former. A similar trend is exhibited in other appliances which use only 15% of energy but contribute up to 28% of the greenhouse gas discharges.
