Use of energy in an average Australian Household
The two pie charts represent the use of energy in various segments of an Australian household and the resultant greenhouse gases as a by-product of that energy use in an unspecified period of time.
Heating and water heating accounted for the highest energy use in an Australian household with 42% and 30% energy usage respectively. Other segments like cooling, lighting and refrigeration’s combined energy utilization was more than one-tenth, whereas other appliances consumed 15% of energy.
Contrary to its energy consumption of less than a-fifth, other appliances produce nearly double the amount (28%) of greenhouse gases. Gas emissions by refrigeration and lighting also increased two-folds to 8% and 14% compared with its energy intake of 4% and 7% respectively. Cooling, on the other hand, produces only 3% of greenhouse gas. Surprisingly, emission of greenhouse gas by heating is significantly lower to 15% in comparison with its energy intake of more than two-fifths.
Overall, it is evident that heating and water heating accounted for major energy use, whereas cooling, refrigeration, lighting and other appliances consumed less energy on average. However, the resultant greenhouses gases are given-off in large amounts by water heating, and other appliances, while cooling, lighting, refrigeration, and heating produce lower amounts of gases.
