Energy Use

The manufacture and processing of steel is an energy-intensive process.

Significant quantities of coal are used in the blast furnace, natural gas and electricity to reheat and roll steel slabs into thin sheets, and electricity is tapped for coating and painting a range of downstream steel products.

BlueScope Steel's global energy consumption has remained relatively constant. In the fiscal year 2005/06, 139.1 petajoules of energy was used.

The Company uses an energy intensity index to calculate how efficiently we use energy compared to a base year. This year the energy intensity index remained relatively constant at 23.6.
