Energy Consumption

The pie charts illustrate electricity consumption by various fields in Eastern Australia in two year 2007 and 2010.

It is clear that the consumption of electricity from those sectors remained unchanged except for Aluminium, Manufacturing and Other metal fields over the period shown. Additionally, the figures for residential and commercial sectors were by far largest.

In 2007, residential areas consumed 28% of total electricity, while 23% of electricity was consumed for conmmercial purposes. There was 13% of electricity consumed by manufacturing and aluminium sector each, whereas the figures for other metals and mining were slightly lower, at 12% and 9% respectively. By
contrast, electricity consumption from transport and agriculture made up only negligible figures.

In 2010, while the percentage of electricity consumed by other metals rose significantly by 6%, those of aluminum and manufacturing fields saw a slight fall to 11% and 9% respectively. Interesting, the proportions of electricity consumed by the other sectors were all as similar as initial figures.
