Editing Hall–Héroult process (section)

===Economic impact===
Aluminium produced via the Hall–Héroult process, in combination with cheaper [[electric power]], helped make aluminium (and incidentally [[magnesium]]) an inexpensive commodity rather than a precious metal.

This, in turn, helped make it possible for pioneers like [[Hugo Junkers]] to utilize aluminium and [[Magnesium alloy#Aluminium alloys with magnesium|aluminium-magnesium alloys]] to make items like metal airplanes by the thousands, or Howard Lund to make aluminium fishing boats.<ref>{{cite web|url= https://www.in-depthoutdoors.com/community/forums/topic/ftlgeneral_69525/|title= Lund Boat Company Founder Dies at 91|date =October 24, 2003|website = In-Depth Outdoors}}</ref> In 2012 it was estimated that 12.7 tons of CO<sub>2</sub> emissions are generated per ton of aluminium produced.<ref name= "Das2012">{{cite journal|last1=Das|first1=Subodh|title=Achieving Carbon Neutrality in the Global Aluminum Industry|journal=JOM|volume=64|issue=2|year=2012|pages=285–290|issn=1047-4838|doi= 10.1007/s11837-012-0237-0 |bibcode=2012JOM....64b.285D|s2cid=59383624}}</ref>

In the 20th and 21st century the aluminum industry due to its large-scale requirements for cheap electricity has often been sited in locations where such electricity is available. For example Iceland, a country with no notable bauxite reserves and [[demographics of Iceland|a population]] of less than half a million, is the world's [[List of countries by aluminium production|twelfth largest aluminum producer]] due to the availability of [[energy in Iceland|cheap and plentiful]] electricity, particularly [[hydropower in Iceland|hydropower]]. Similarly [[Aluminerie Alouette]] in [[Sept-Îles, Quebec]] is dependent for its electricity needs on the 5,428 MW [[Churchill Falls Generating Station]] operated by [[Churchill Falls (Labrador) Corporation Limited]]. The [[company town]] of [[Kitimat]] in [[British Columbia]] was built by [[Alcan]] to meet the growing demand for aluminum in the postwar era. It makes use of the [[Kenney Dam]] built to power the smelters. The [[Tiwai Point Aluminium Smelter]] on the South Island of [[New Zealand]] consumes some 570 MW of electricity, most of which is supplied by nearby [[Manapōuri Power Station]]. This amounts to around a third of the electricity demand of South Island and 13% of that of the entirety of New Zealand. [[Borssele Nuclear Power Station]] was built primarily to supply electricity to an aluminum smelter operated by French [[Pechiney]] at the time.
