Energy Consumption Energy Consumption by Fuel | Fuel Consumption by End Use | Energy Consumption by Sector | Energy Expenditures | Energy Intensity About two-thirds of the total energy input to the aluminum industry is consumed during the electrolytic reduction of aluminum oxide, also known as alumina, to aluminum. This process has an electricity requirement of about 6.8 kWh/lb of aluminum produced. Alumina refining, in which alumina is extracted from bauxite ore via the Bayer process using natural gas, accounts for another 10% of industry energy use. Scrap melting (using natural gas) and anode production (split between electricity and natural gas) each represent approximately 5% of total energy use. Electricity is used to power casting and rolling mills, as well as to heat, light, and cool facilities.
