The pie charts illustrate the information about methods of using energy in an average Australian household and greenhouse gases emitted by those uses. Heating emits very little greenhouse gases among other uses of energy.
30% of energy is used for water heating and little over its percentage the harmful gases are produced by this method (32%). Refrigeration other appliances and lighting releases the doubled amount of harmful material than its source energy. Refrigeration (7%), other appliances (15%) and lighting (4%) left out the 14%, 28% and 8% of gases in the air. Cooling just took the 2% of total energy provided by houses and release almost the same amount of gases in environment.
Heating is only the energy consumer that take the most of energy(42%) from household and release only 15% greenhouse gases, which is three times of its total energy consumption.
Overall it can be seen that only heating releases the least amount of material that is harmful for the air.
