I stumbled on this when trying to calculate the amount of energy used refining [Aluminium](http://en.wikipedia.org/wiki/Aluminium) in the US.

In case you were wondering, using Google’s (via the [CIA](http://www.cia.gov/cia/publications/factbook/rankorder/2042rank.html)) figure of 3,660,000,000,000 kWh and a usage rate of 5% according to [Nature’s Building Blocks](http://www.amazon.com/gp/product/0198503415/qid=1144809465/sr=1-2/ref=sr_1_2/104-7536840-2492720?s=books&v=glance&n=283155) by John Emsley, the final figure comes out to 186 billion kWh devoted to aluminium production annually.
