The first chart below shows how energy is used in an average Australian household. The second chart shows the percentage of greenhouse gas emissions which result from this energy use.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
» You should write at least 150 words.
The percentage of household energy use in Australia:
The percentage of greenhouse gas produced in Australia:
Sample Answer 1:
The first pie chart illustrates average energy usages in a typical Australian family while the second pie chart shows the percentage of greenhouse gas emission from this energy consumption. As is presented, water heating and heating & cooling consume the highest energy and they produce the highest percentage of greenhouse gas in Australia.
According to the given data, water heating system consumed 23% of total energy consumption in an Australian household while heating and cooling system require 20% energy. Refrigeration consumed 12% energy which is larger than that of energy requirement for cooking and lighting. Finally, 5% energy is consumed in standby mode and the remaining 24% energy is required for all other household appliances.
On the other hand, heating and cooling systems contribute to the highest percentage of greenhouse gas emission which is 38%. Water heaters, though require more energy than heating and cooling, emit comparatively lesser greenhouse gas (25%). These two systems produce the highest percentage of greenhouse gas in Australia. Cooking, lighting and refrigeration generate 18% greenhouse gas in total and all other appliances and standby mode generate 19% such gas.
Sample Answer 2:
The first pie chart compares the power consumptions in a typical Australian house whereas the second one presents data on the percentages of greenhouse effects of these power-consuming equipment. As a general trend, the more energy a household appliance use, the more greenhouse gas it emits.
As can be seen, water heating, keeping the house warm or cool consume almost half of the energy required in an average Australian family. Cooking, standby and lighting all together utilise around 20% power while refrigerators alone need 12% electricity. All other appliances consume the rest one-quarter energy share.
Interesingly, there is a correlation between the percentage of energy a particular device requires to run and the percentage of greenhouse gas this device produces with the exception of heating and cooling device. Heating water, warming and cooling the rooms attribute to more than half of the total greenhouse gas emission. Cooking, stand by and lighting combinedly contribute to 14% gas production which is almost same as the amount produced by other appliances in a house.
In summary, heating and cooling devices emit the highest percentages of greenhouse gas though they consume less power than water heaters. Other devices contribute to emit dangerous gases based on the percentages of energy they require to function.
