The first chart shows how energy is used in an average Australian household. THe second chart shows the greenhouse gas emissions which ressult from this energy use.

The first pie diagram illustrates the proportion of energy used by appliances in Australian households and the second pie chart presents the fraction of the emission of harmful gas in six household systems.

Overall

,

it is clear that

the heating system consumes a vast amount of energy

while

cooling uses the least.

Moreover

, greenhouse gas was emitted mainly by heating

water

whilst cooling remains in the final place.

To begin

with, the percentage of heating in Australian households occupied a gigantic 42% followed by using it to heat

water

at 30%. Other appliances were 15% and cooling came in

last

place with only a meagre 2%. What is interesting to note is other appliances were less than

water

heating by exactly two times.

On the other hand

, the greenhouse gas was mainly released by the process of heating

water

, with an enormous 32%,

likewise

, other devices registered a massive 28%. Heating and refrigeration had almost the same per cent which were 15% and 14% respectively,

besides

, the cooling system only accounted for a minuscule 3%. What is surprising to see is lightning, at 8%, was totally different from the

water

heating around 4 times.
