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 provided pie charts elucidate the usage of

energy

in Australian households and the emissions of

greenhouse

gases

from them. Looking from an

overall

perspective, it is readily apparent that the highest

amount

of

energy

is consumed for heating purposes,

however

, emissions of

greenhouse

gases

are done in substantial amounts by water heating. Cooling consumes the lowest

energy

and emits the least

amount

of

greenhouse

gases

. The proportion of

energy

consumed for heating purposes is 42%. It is followed closely by water heating at 30%, half of

this

amount

is consumed by other appliances. Refrigeration, lighting and cooling consume significantly less

amount

of

energy

which is 7%, 4% and 2% respectively. Analysing the chart of

greenhouse

gas emissions, water heating and other appliances release exactly 50% of

greenhouse

gases

which are found to be the most harmful to the environment. Heating releases 15% of

greenhouse

gases

into the atmosphere. Refrigeration releases 14% of

greenhouse

gases

which is double the number of

energy

consumed by it. Lighting and cooling are both below 10% in the emission of environmentally harmful

gases

.
