The pair of charts compares 6 different categories (heating, cooling, lighting, water heating, refrigeration, and other appliances) in terms of their energy use and gas emissions in Australian households. Units are measured in percentages. As far as household energy consumption is concerned, heating is the dominant energy consumer, followed by water heating; remaining categories account for a small amount, except for other appliances. When it comes to their gas emissions, the water heating system is the largest contributor, followed closely by other appliances. Cooling and lighting is the smallest contributors, while heating and refrigeration systems show almost similar amounts. Of particular note is that cooling and lighting is regarded as the most economic and efficient appliances.
Starting with Australian household energy consumption, energy allocated to heating systems accounts for 42%, surpassing water heating systems with 8%, which two times larger that of other appliances. 7% of energy is allocated to the refrigeration system, compared to lighting at 4%. The smallest amount of energy is used by the cooling system at 2%.
With regards to their gas emissions, the dominant contributor is the water heating system at 32%, followed closely by other appliances at 28%. Heating and refrigeration emit similar amounts of gas emissions at 15% and 14% respectively. Only 8% of gas emissions are observed in the lighting system, whereas 3% emissions are in cooling.
