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 first pie chart depicts data about the proportions of

energy

used in 6 different categories,

whereas

the following chart demonstrates the gas

emissions

caused by

this

energy

consumption.

Overall

,

it is clear that

3 different categories , namely heating, water heating and other appliances were used the most in terms of

energy

usage and

consequently

caused the highest proportion of CO2

emissions

,

while

the lighting and cooling,

on the other hand

, were the lowest figures in both charts. Looking into more detail, the amounts of

energy

spent on heating and water heating were 42% and 30% respectively.

Furthermore

, electricity used for cooling, lighting and refrigeration was 13% altogether, which didn't even exceed the

energy

usage of other appliances.

According to

the second graph, as can be vividly seen the

emissions

from heating the water and other usages were the leaders at 32% and just under 30% respectively.

In addition

to

this

, the heating and refrigeration categories were approximately at the same level, at nearly 15% on average, which was 5 times higher than carbon

emissions

from cooling.

Also

, the figure for lighting was 8% in terms of greenhouse gas

emissions

.
