The pie charts show the distribution of electricity consumption across 8 various sectors in Eastern Australia in 2007 and 2010.
Overall, there were minimal variations over the period, as most categories remained unchanged, with commercial and especially residential sectors remaining the major water consumers. ‘Other metals’ exhibited a notable rise, whereas manufacturing and aluminum demonstrated a considerable decline. Notably, transportation and agriculture demanded the lowest proportion of energy, while the distribution was more even across the rest four categories.
Most industries in question experienced no change in their electricity consumption. Residential use emerged as the largest sector, with a stable share of 28%, slightly higher than the figure for the commercial industry, which ranked second at 23%. Similarly, mining, transportation, and agriculture remained stable in their energy consumption throughout the timeframe. Mining accounted for 9%, while agriculture and transportation significantly lagged behind, each constituting 1%.
Other, unspecified metals, on the other hand, were the only sector to see a marked increase in their electricity usage. In 2007, the percentage consumption stood at 12%, which rose to 18% by 2010, becoming the third major industry.
Conversely, manufacturing and aluminum followed a downward trajectory. The steepest drop was observed in the former, with the figure falling from 13% to 9% in 2010. A similar, though less drastic, dip occurred in the aluminum industry, where the electricity use decreased to 11% from an initial 13%.
