The first pie chart illustrates the energy consumption in an average Australian family while the second one depicts how much greenhouse gas emissions related from this utilization.

Overall, heating and water heating made up the largest portion in energy use in Australian households. However, it is not water heating and other appliances emitted the most greenhouse gases in the air.

42% of total energy use allocated for heating followed by water heating, with 30%. The figure for energy consumption in other appliances is only half of that in water heating and doubles the amount in refrigeration. Lighting and cooling used the least energy, constituting 4% and 20% respectively.

Water heating contributes 32% greenhouse gases. The figures for emitting greenhouse gases in refrigeration and heating are nearly the same, with 16%, which is half of that in other appliances. The remaining 11% gas emissions is attributed to lighting and cooling.

The initial pie chart presents the energy usage within an average Australian family, while the second one illustrates the amount of greenhouse gas emissions resulting from this consumption.

In general, heating and water heating constitute the largest portion of energy consumption in Australian households. However, it is not water heating and other appliances that contribute the most to greenhouse gas emissions in the air.

A substantial 42% of the total energy consumption is allocated to heating, followed closely by water heating at 30%. The energy consumption for other appliances is merely half of that used for water heating, and it surpasses the energy used in refrigeration by twice the amount. Lighting and cooling, on the other hand, account for the least energy usage, constituting 4% and 20%, respectively.

Specifically, water heating is responsible for 32% of greenhouse gas emissions. The figures for greenhouse gas emissions from refrigeration and heating are nearly identical, both standing at 16%, which is half of the emissions from other appliances. The remaining 11% of gas emissions are attributed to lighting and cooling.
