The pair of charts compere 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 dominant energy consumer, followed by water heating, remaining categories account for a small amount except from other appliances. When it comes to their gas emissions, water heating system is the largest contributor, followed closely by other appliances. Cooling and lighting is the smallest contributors, while heating and refrigeration systems shows 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 system accounts for 42%, surpassing water heating system with 8%, which two times larger than other appliances. 7% of energy allocate to the refrigeration system, compared to lighting at 4%. The smallest amount of energy is used by cooling system at 2%.
With regards to their gas emissions, dominant contributor is water heating system at 32%, followed closely by other appliances at 28%. Heating and refrigeration emerge similar amount of gas emission at 15% and 14% respectively. Only 8% of gas emission observed in lighting system whereas 3% emissions in cooling.
