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 two pie charts give information about the percentages of

energy

consumption

in an average Australian household and the

proportion

of

greenhouse

gas

emissions

released by each

energy

consumption

.

Overall

,

it is clear that

heating and

water

heating have the biggest

share

among Australian household

energy

use,

while

the

consumption

of cooling stands

last

.

Moreover

, the largest

proportion

of

greenhouse

gas

emissions

allocates to

water

heating, followed by other appliances. The first pie chart shows that the

share

of heating is the biggest

consumption

of Australian household

energy

usage with almost half of all

share

.

Water

heating ranks second with 30%, and other appliances have a considerable

figure

among

energy

usage (15%).

Furthermore

, the

figure

for lighting and cooling together is almost the same as that for refrigeration by a narrow margin of 7%. The biggest

proportion

of

greenhouse

gas

emissions

accounts for

water

heating with about one-third of all

share

. Other appliances have a substantial

figure

in

greenhouse

gas

emissions

with 28%. There is little difference between the

figure

for heating and refrigeration, the

figure

for the former is 15%.

Although

cooling ranks

last

with 3%, the

share

of lighting in

greenhouse

gas

emission is considerable with approximately one-tenth of all

proportion

.
