Article Summary

• China forced aluminum smelters to shut down for over-use of energy. The coal-fired power, popular with Chinese producers, is under restriction by the government.
• China used coal for power for near 90% of its aluminum smelting in 2019, compared to North America, which is about 82% from hydroelectric
• China's Inner Mongolia curbed aluminum output because of energy-use (read: "coal") limits
• Future aluminum expansions are under threat
• Less aluminum production in China has coincided with high imports — early-2021 imports of unwrought metal were higher than any period going back to 2009-2010
