The first chart illustrates the proportionality of energy usage in a normal Australian household and it is followed by another chart showing the greenhouse gas emission associated with each of the usages.
As for the energy usage, heating is the most energy-intensive usage, being responsible for 42 percent of the total usage. Water heating is at the second place with 30 percent. Refrigeration, lighting and cooling are next in line with only 7, 4 and 2 percent respectively. Other appliances occupy 15 percent of the usages summed up together.
However, the ranking doesn’t stand looking at the greenhouse gas emissions as reflected in the second chart, and major changes are recognizable. Water heating is in the first place associated with 32 percent of pollutions, roughly the same percent as it’s share in the first chart. Unexpectedly, other appliances take the second place with also twice the portion in emissions. (28 percent) On the other hand, heating is shockingly at third place with almost one third of it’s share in usage, releasing only 15 percent of the emissions. Refrigeration and lightning have also double the amount in emissions with 14 and 8 percent respectively, with cooling staying the same with only 3 percent emission.
