$70,000 per minute power in NSW, page-22

This is what is going to happen even more in Australia. Workers will not be happy about losing their jobs.  The greenie morons like Adam Brandt who want a solar/windmill future  will only result in closing down  all Australian Industry.
You cannot operate smelters using intermittent power, smelters need reliable 24/7 power

Stopping the demise of Europe’s aluminium industry

The fact that 700 workers at Alcoa’s Spanish aluminium plants in La Coruña and Avilés are rioting to keep their jobs should give pause to policymakers in Brussels. The two towns have been in uproar ever since the American producer announced last October that the plants would be closed due to a series of structural factors (such as high energy costs and Chinese overproduction). Making matters worse, the American company announced earlier this week that San Cipriàn, the third (and last) smelter still operating in Spain, would also be closed unless a solution is found for the country’s high electricity prices.
Alcoa’s moves add pressure on the European Commission to radically adapt its out-dated trade and industrial policies. Saddled with deep disadvantages, the EU has lost a third of its total primary aluminium output between 2002 and 2016 – in just fourteen years, more than 10 smelters have closed up shop.
