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 illustrates the rate of energy consumed in six different categories by an Australian family, on average,

whereas

the following picture depicts the usage of energy in those categories to produce greenhouse gases, in percentwise.

Overall

, when it is closely scrutinized, heating was used the most in terms of energy usage.

On the other hand

, water heating was the most significant contributor to releasing greenhouse gases into the atmosphere. Cooling makes up the smallest part of both charts. In the first case, heating accounts for the largest contribution, 42% of the total consumption. Water heating and cooling together make up around one-third of the usage.

Moreover

, refrigeration, lighting, and other appliances use roughly one-quarter. In the second scenario, water heating was the largest significant source of greenhouse gas production, comprising almost a third of the total production. The second largest amount of gas generation comes from other appliances, at 28% of the total. Surprisingly, heating is only responsible for 15% of total emissions, and

this

figure is the same as for refrigeration. The remaining 11% results from cooling and lighting together.
