Aluminum smelters in the energy transition: Optimal configuration and

The percentage of renewable energy sources used in the primary aluminum smelting power consumption today is a little less than 28% and is almost entirely based on hydro power plants. About 10% of global production is located in the Middle East taking advantage of fossil fuel (primarily natural gas) availability often at subsidized prices.
