MODEL ANSWER:

The amount of energy consumed by various household activities in Australia and the proportion of greenhouse gas emission resulting from this are picturised in the given pie charts.

It is clear from the first chart that, an average Australian household uses the highest amount of energy (42%) for heating, which is 12% more than the energy consumed for water heating. Refrigeration, lighting and cooling consume just under one-sixth of the total energy consumption of an Australian household (7%, 4%, 2% respectively), whereas, cooling consumes the least amount of energy. The share of energy consumption by means of other appliances is also seen similar (15%).

Turning to the proportion of greenhouse gas emission, refrigeration and lighting is seen emitting 14% and 8%, which is exactly the double of the energy they consume. Nearly one-third of the gas emission is attributed to water heating, which is the highest and is over double than emission by means of refrigeration and heating. The proportion of gas emitted by cooling accounts to just 3%, whereas the emission from other appliances is 28% out of the total proportion (Second highest cause of greenhouse gas emission).

Overall, it can be seen, the rate of Australian household energy used and greenhouse gas emission has no co-relation in between.
