Energy Consumption Energy Consumption by Fuel | Fuel Consumption by End Use | Energy Consumption by Sector | Energy Expenditures | Energy Intensity The production of primary aluminum relies on an electrolytic process and is electricity-intensive. According to the most recent Manufacturing Energy Consumption Survey (MECS), the U.S. aluminum industry consumed about 1 quadrillion Btu of energy in 1998 including losses associated with the generation and transmition of electricity at utilities. This amount represents slightly more than 1% of domestic energy use and 3.3% of all U.S. manufacturing energy use. According to a study sponsored by DOE, the total energy consumption associated with the production of molten primary aluminum in 1995 was 522 trillion Btu. [DOE 1997] (Trillion Btu)
Source: MECS 1985, 1988, 1991, 1994 and 1998 Nearly 76% of the aluminum industry's energy comes from electricity (including losses) Fuel Consumption by End Use The vast majority of the energy is consumed during the electrolytic reduction of alumina (AI2O3 to aluminum) Energy Consumption by Sector Nearly two-thirds of all energy consumed by the industry is for primary aluminum production Energy Expenditures One-third of the average cost of aluminum is for the energy required to make it Energy Intensity Energy intensity measures the energy consumed per dollar of products shipped Page last modified on
