Band 6+: 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.

The given pie charts representing Australian household energy use and greenhouse gas emissions respectively.

According to energy chart, heating has the highest amount with 42% and water heating follows it with 30%. Refrigeration 7%, other appliances 15%, lighting 4%, and cooling 2%.

In the greenhouse gas emissions chart show that, despite the heating is the most using energy, greenhouse gas emission is lower with 15%. Only heating has lower greenhouse gas emission. Refrigeration and lighting is same trend in greenhouse gas emission with 14% and 8% respectively. Because first pie chart shows that they are used half the rate of greenhouse they give. Other appliances has similar trend with 28%. Cooling has the lowest rate in the second chart with 3% and water heating has the highest rate with 32%. However, we can say that cooling produces more gas than water heating proportionally.

Overall it is clear that heating is the most eco-friendly energy use and lighting and refrigeration are the worst energy use for our environment.
