Aluminum and manufacturing ranked third, each making up 13%, which is one percentage point more than other metals. 9% of electricity was used in mining sector. Meanwhile, agriculture and transport used 1% of electricity each, which is the smallest share in the chart.
Turning to the changes occurred in 2010, the figure for residential and commercial activities leveled off. Similarly, mining sector had the same share as in 2007. In comparison, the proportion of electricity in other metals rose noticeably to 18%, surpassing manufacturing and aluminum. By contrast, their electricity use decreased slightly, with manufacturing dipping to 9% and aluminum falling to 11%. Finally, transport and agriculture did not witness any changes in electricity consumption and still had the least proportion.
