Aluminum manufacturers are among the most energy-intensive industries in the world. In 2010, the process used by smelters to refine primary aluminum from bauxite ore consumed approximately 3% of the entire world’s electricity supply. The vast amounts of energy used in this process have driven many aluminum manufacturers to locate their plants in parts of the world where bauxite is plentiful and electricity is relatively inexpensive. Today, there is a new energy-intensive industry that is driving demand for more electricity supplies: cryptocurrencies. According to the Cambridge Center for Alternative Finance, Bitcoin alone, one of the most well-known cryptocurrencies, uses 110 Terawatt-hours of electricity annually, or 0.55% of global electricity supplies. The fact that cryptocurrencies can use more electricity than some small nations has motivated companies that mine Bitcoin to find host locations where electricity is reliable, plentiful, and inexpensive. Bitcoin, Ethereum, Dogecoin, and others have used record amounts of electricity this year, raising concerns around the amount of energy these monetary systems use and the amount of carbon used to supply their facilities.
