A glance at the two pie charts provided reveals a number of clear difference between the proportions of an average Australian family energy use in various form (namely water heating, heating, cooling, lighting, refrigeration and other appliances) and the percentage of CFC release that every energy source listed before is responsible for it.
It is evident from the information supplied that heating and heating water have the two largest proportion with 42 and 30 percent respectively, in stark contrast however, cooling with merely 2 percent and lighting with only 4 percent take place for the lowest percentage of using energy. Refrigeration and other appliances have moderate rate in using energy with 7 and 15 percent respectively.
With regard to producing co2, water heating and other appliances release the highest percentage of greenhouse gas at 32 and 28 percent respectively. However, it is worth nothing that the former CFC emission is almost the same as household use of energy while the latter produced some twice as it use for energy. One particularly interesting fact highlighted by the figures is that the amount of emissions are more than the proportion of energy use except for heating. While CFC release caused by refrigeration, lighting and cooling are double than those of energy use for heating is almost three times less than that of energy use.
