Energy consumption/ton of steel shipped: ↓
The iron and steel industry participates in EPA’s
Sector Strategies Program. To produce steel, Major fuel sources: Coal, natural gas, coke, electricity

processes, which utilize a variety of raw
materials and technologies and have different
energy use profiles:
? Integrated steel mills use a blast furnace to produce molten iron from iron ore, coal, coke,
and fluxing agents. A basic oxygen furnace (BOF) is then used to convert the molten iron,
along with up to 30 percent steel scrap and alloys, into refined steel. Integrated
steelmaking has declined from 52.6 percent of U.S. steelmaking production in 2001 to
44.9 percent of production in 2005 (estimated value updated March 2006).161
? Electric arc furnace (EAF) steel mills utilize steel scrap and up to 30 percent of other iron-
bearing materials to produce steel. EAF steel plants primarily produce carbon steels as
well as alloy and specialty steels. EAF steelmaking has grown from 47.4 percent of U.S.
