▶ Your Answer :
The pie charts compare six different
categories of energy use and greenhouse gas emissions by Australian households.
It is apparent that heating is
the primary purpose to spend household energy on, in Australia, whereas energy
spent for heating water caused the biggest proportion of greenhouse gas
emission. According to the charts, all the categories showed bigger percentages
on greenhouse gas emission in proportion to their actual uses, except for
heating.
42% of household energy in
Australia was used for heating, taking the highest percentage. However, in the
greenhouse gas emission pattern, heating was ranked the third, making up only
close to one-thirds of the energy use figure. Water heating was the second top
reason to spend energy on, accounting for 30% of the total energy use.
Consequently, it caused a similar proportion of greenhouse gas.
The other categories all
showed bigger percentages in emitting greenhouse gas than in the energy use.
Especially, other appliances, refrigeration and lighting saw double the
proportion of energy use on greenhouse gas emission, at 28%, 14% and 8%,
respectively. Cooling was a negligible element on both charts.
