Aluminium
Most commercially produced aluminium is extracted by the Hall–Héroult process. In this process aluminium oxide is dissolved in molten cryolite and then electrolytically reduced to pure aluminium. Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production.
