I stumbled on this when trying to calculate the amount of energy used refining Aluminium in the US.

In case you were wondering, using Google’s (via the CIA) figure of 3,660,000,000,000 kWh and a usage rate of 5% according to Nature’s Building Blocks by John Emsley, the final figure comes out to 186 billion kWh devoted to aluminium production annually.
