Task 1 / IElTS exam The chats illustrate the consuming of energy that has been used in an Australian household and the rate of emissions from the greenhouse gas. Overall, there are six appliances in the household using the energy (Water heating , heating ,refrigeration, cooling , lighting and other appliances).The biggest sector of energy use was by heating and water heating , reaching more than 70% of energy use, while the smallest sector was the cooling process. The most significant rate of the emission was by water hearing process and the smallest contribute was from the cooling sector. Although the heating process, including the water heating, counted for 72% of energy use in household, it contributed with just 47% from the total emissions of greenhouse gas .On the other hand, it was very notable that the other appliances (Cooling, lighting and refrigeration) consumed the lowest parts of energy (2%, 4% and 7% respectively).However they have produced a huge part of gas emissions, reaching 3%, 8% and 14% respectively. In addition, the refrigeration appliance used just 7 % of the energy, but it had the same trend and of Cooling, lighting and refrigeration and produced 14% of the emissions.
