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 the information by selecting and reporting the main features, and make comparisons where relevant.

The pie charts compare the percentages of energy consumed for various purposes and how much greenhouse

gas

is emitted by an average Australian family.
