▶ Your Answer :
According to
these graphs, the information about how energy is
used in an average Australian household and how this energy
use result in the greenhouse gas emissions is given.
Firstly, the largest portion of energy used by Australian household is for heating,
which consists of forty two percent of total. Energy for water heating is
ranked in the second place with thirty percent of total. The other usages of
energy are for other appliances, refrigeration, lighting and cooling, which
constitute fifteen percent, seven percent, four percent and two percent,
respectively.
In the second graph, the heating, which is the first place of energy use of
Australian household, takes only fifteen percent of total greenhouse gas
emissions in Australia. On the other hand, the water heating is shown to
produce the greatest amount of greenhouse gas emissions, consisting thirty two
percent of total. Greenhouse gas emissions by other appliances, refrigeration,
lighting and cooling is constituting of twenty eight percent, fourteen percent,
eight percent and three percent each, and they are in the same order as in the
first chart.
In conclusion,
almost half of Australian household use energy for the heating, whereas it only
results in greenhouse gas emission by fifteen percent. The water heating takes
a similar proportion, about thirty percent, both of energy use and of
greenhouse gas emission.
