IELTS Graph # 19 - The pie charts show how energy is used in an average Australian household, and the resultant greenhouse gas emissions.

Graph # 19

The first chart below shows how energy is used in an average Australian household. The second chart shows the greenhouse gas emissions which result from this energy use. Summarise this information by selecting and reporting the main features, and make comparisons where relevant.

The two pie charts represent the use of energy by an average Australian household and emission of greenhouse gas as a by-product of this energy use.

At a glance, it is clear that the highest energy consumption is because of heating, whereas the highest greenhouse gas emission is due to the usage of water heating appliances.

At 42%, heating makes up the largest proportion of household energy consumption, but its effect on the greenhouse gas emission is only 15%; this is almost half of the emission rate caused by water heating which amounts to 32%. However, the use of other appliances is only 15% of the total energy, but its corresponding greenhouse gas emission is almost twice as much of that source, i.e., 28%.

Moreover, it is prominent that although refrigerators and lighting use comparatively less energy – 7% and 4% respectively, they cause exactly double the gas emission each. Furthermore, except for cooling which uses the least energy of all, all the other appliances contribute to emitting significant amounts of dangerous gases based on the ratio of energy they require.
