Metalcasting is among the most energy-intensive industries in the
United States. The heating and melting of metals consumes large
amounts of energy; an average of 55% of total energy costs can be
attributed to melting. [Bates
1997] According to the most recent Manufacturing Energy Consumption
Survey (MECS), about 103 trillion Btu of energy was consumed by
NAICS 331511 (iron foundries) in 1998. Total industry energy consumption
was 236 trillion btu, representing about 1% of all U.S. manufacturing
energy use. [MECS 1998]

NOTE: Years prior to 1994 do not include adjustments for energy
shipped off-site. Does not include losses incurred during the distribution,
generation, and transmission of electricity.
Natural gas, coke, and electricity (excluding losses)
are the primary fuels used in the industry
More than half of all industry energy use is consumed
during metal melting
NAICS 331511 represents the majority of industry
energy use
The industry's energy expenditures were about 5%
of the value of its shipments in 1998
Energy intensity measures the energy consumed per
dollar of products shipped
