I'm in agreement with you on the jobs .. but power draw wise??
An aluminium smelter uses an immense amount of electricity, requiring about 14,000 kWh per metric ton of aluminium produced. Because it takes so much power—roughly equivalent to powering a mid-sized city like Nashville or Boston—electricity can make up to 40% of the total production cost.
That's quoted from a google AI summary query, sure - but I've had family members work the S.Australian smelters and they're beasts for power consumption.
