The provided pie charts illustrate the distribution of electricity consumption across various sectors in Eastern Australia for the years 2007 and 2010.
Overall, while the residential and commercial sectors maintained their consumption levels, notable shifts occurred in the contributions of the aluminum, manufacturing, and other metals sectors between the two years.
In 2007, electricity consumption was predominantly characterized by significant usage in the residential and commercial sectors, which accounted for 28% and 23%, respectively. Both the aluminum and manufacturing sectors contributed equally to the overall consumption at 13% each. In contrast, the mining and other metals sectors represented lower consumption rates, with 9% and 12%, respectively. Furthermore, agriculture constituted the minimal consumption segment at a mere 1%.
By 2010, the electricity consumption landscape experienced notable transformations. The residential and commercial sectors maintained their shares at 28% and 23%. However, the other metals sector saw a marked increase to 18%, displacing aluminum which declined to 11%, along with manufacturing which decreased to 9%. The mining sector’s share remained stable at 9%, while agriculture continued to exhibit negligible consumption at 1%. Overall, this indicates a shift towards greater electricity consumption in the other metals sector, reflecting changing dynamics within Eastern Australia’s industrial landscape.
