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.
Australian Home and Energy Usage
The two pie charts present the proportion of energy use in an average Australian household and the greenhouse gas emissions from each activities. The total amount of energy use are divided into six categories as follows: water heating, refrigeration, lighting, cooling, heating and other appliances.
According to the first chart, heating and water heating are the major energy use among all activities, which contribute 42% and 30% respectively; while refrigeration, lighting and cooling have smaller percentage, at 7%, 4%, 2% respectively.
When it comes to greenhouse gas emissions. water heating and other appliances are the top two activities, which account for 32% and 28%; while lighting and cooling are the two that generate less greenhouse gas emissions, at 8% and 3%. It is worth noting that the energy use of heating is around 40% but its greenhouse gas emissions is less than 20%.
It can be concluded from the two chart that heating and water heating are the two large sources of consuming energy; while water heating and other appliances generates more greenhouse gas emissions than other activities do.
