Task 1: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 two pie charts illustrate how energy isused in an average Australian family and the greenhouse gas emissions caused byeach kind of energy use respectively.

In the first chart, 42% of the energy isused in heating, which is followed by water heating (30%) in every Australianhousehold. However, only 2% of the energy is exploited for the purpose ofcooling, which is a bit less than the consumption of energy used in lighting(4%). The remaining energy is exploited in refrigeration and other appliances, whichtakes up 7% and 15% respectively.

As shown in the second pie chart, thelargest source of the greenhouse gas emissions is the use of water heating(32%), instead of heating, which only accounts for 15%. The next largest sourceof the greenhouse gas emissions is the use of other appliances (28%). Moreover,the three least greenhouse gas emissions are caused by the energy use inrefrigeration (14%), lighting (8%) and cooling (3%).

In conclusion, despite the largestconsumption of energy is used in heating by Australian families in average, itonly produces a relative small percentage of the total greenhouse gasemissions. It may result from an effective improvement in the technology ofcontrolling the harmful gas emissions in the process of heating.
